What Affects the Cost of Double Glazed Windows?

Wed, 21 Oct 2026 18:09:59 GMT

Double glazed windows cost different amounts from one home to the next because every price is built from the same handful of factors: window size and number, opening style, frame material, glass package, installation complexity and compliance needs. At RJV Industries , we supply and install uPVC double glazed windows across Nowra, the Shoalhaven, Wollongong and the Illawarra, and in this guide we explain what drives the cost of double glazed windows so you can make sense of a quote before you get one.

Key Takeaways

There is no single per-window or per-square-metre price for double glazing. The cost depends on size, style, frame material, glass, installation and compliance.
Online averages rarely match real quotes because they ignore site access, removal of old windows, bushfire (BAL) requirements and finishing work.
Our uPVC double glazed windows are WERS rated, designed and manufactured in the USA, and available supply-only or supply and install.
Matching the glass package to each room, instead of upgrading everything to the top specification, is one of the simplest ways to control cost.
The only reliable figure comes from a free, no-obligation measure and quote. Call RJV Industries on 0457 431 660.

How Double Glazing Is Priced (and Why There's No One-Size-Fits-All Cost)

Double glazing is priced per opening, with each window or glazed door quoted on its own size, frame, glass, hardware and labour. That's why two homes with the same number of windows can get very different totals, and why a figure you read online for Melbourne or Perth tells you little about a home in Bomaderry or Figtree.

National "average" price tables are a common source of confusion for South Coast homeowners. They usually leave out the parts of a job that move the price the most: removing existing windows, making good around new frames, meeting bushfire or safety glazing rules and getting materials onto a tricky site. We'd rather you understand what goes into the number than anchor to a figure that was never about your house.

At RJV Industries we prepare an itemised quote after a site measure, so every opening reflects what it actually needs. If you're budgeting early, think in terms of total glazed area and how complex each opening is, then let a measure and quote turn that into a real figure.

Window Size, Quantity and Configuration

The total area of glass and the number of openings are the first things that shape the cost of installing double glazed windows. Bigger windows need more glass, more frame and heavier hardware, and very large panes may need thicker glass or reinforced frames to meet structural and safety standards.

Small windows aren't always cheaper per square metre, though. Every opening carries its own seals, hardware, frame sections and installation time, so a row of small windows can cost more per square metre than one larger panel.

The opening style matters as much as the size:

Fixed windows are the simplest: no moving parts, fewer seals and minimal hardware.
Awning and casement windows add hinges, stays, locks and weather seals.
Sliding and double hung windows need tracks, rollers and balanced sashes.
Sliding and bi-fold doors carry the most glass and hardware, and usually the most installation work.

A small fixed bathroom window and a large sliding door onto a deck in Berry sit at opposite ends of the scale, even with the same frame and glass. Style is one of the main reasons two quotes can look so different.

Frame Material: Why uPVC Often Delivers the Best Value

Frame material affects both what you pay upfront and what you spend looking after your windows over time. Across NSW, the three common choices are uPVC, aluminium and timber.

uPVC frames are rigid and naturally insulating, they never need repainting, and they won't rust or rot in salt air. Our uPVC frames are WERS rated and designed and manufactured in the USA.
Aluminium frames conduct heat and cold readily, which works against the insulated glass they hold. Thermally broken aluminium closes some of that gap, but the extra manufacturing lifts the price.
Timber frames have a traditional look but need regular painting or staining and can swell or rot in coastal moisture, which adds ongoing cost in Shoalhaven and Illawarra conditions.

If you're weighing up frames in more detail, our guide to why uPVC windows and doors are a durable, low-maintenance choice covers the long-term side. For most South Coast homes, uPVC gives the best balance of upfront cost, thermal performance and low upkeep.

Glass Type and Performance Options

The glass inside each double glazed unit is one of the biggest variables in both performance and price. Clear double glazing, Low-E coatings, gas fills, laminated and toughened glass all cost different amounts and do different jobs.

Clear double glazing: two panes with a sealed gap. A solid step up from single glazing.
Low-E glass: a microscopically thin coating that reflects heat, helping keep warmth in during winter and limit heat gain on west-facing windows.
Argon gas fill: a denser gas than air between the panes, which slows heat transfer.
Laminated glass: holds together if broken and helps with security and sound.
Toughened glass: required in certain positions, such as doors, low windows and wet areas.

Our standard Premium glass package pairs one Low-E pane with one clear pane and an argon fill. We also offer triple pane Advanced and Advanced Max packages; you can compare all three on our glass options page. Not every room needs the top specification. Matching glass to each room's use, orientation and noise exposure is a smart way to manage the overall cost. For more on why the glass matters, see how double glazed windows are more energy efficient .

Installation Complexity and Site Access

Installation is where a window's thermal and acoustic performance is either locked in or lost, and it's also where costs vary most from job to job. Proper sealing, alignment and weatherproof flashing are non-negotiable, and the effort to get there depends on your home.

Single-storey homes with clear access are the most straightforward.
Second-storey windows may need scaffolding or lifting equipment.
Steep, narrow or hard-to-reach blocks, common in older parts of Wollongong and around Kiama, add time and logistics.
Replacing windows in a lived-in home means protecting interiors, managing dust and carefully removing old frames.

RJV Industries offers supply-only for builders and experienced renovators, and full supply and installation for homeowners. We don't recommend DIY installation, because poor sealing can lead to leaks and undo the performance you've paid for.

Working With Existing Windows: Retrofit vs Replacement vs Secondary Glazing

Many South Coast homes already have aluminium or timber windows, and how you deal with them has a big influence on cost. There are three broad approaches.

Retrofitting puts new double glazed units into existing frames. It only works when the frames are sound, square and deep enough for a thicker sealed unit, and adapting old frames can add labour.
Secondary glazing adds a separate inner pane behind existing single glazing. It keeps the outside appearance unchanged, which can matter for heritage or strata homes, but it doesn't perform like a factory-sealed unit in a new frame.
Full replacement with new uPVC double glazed windows gives the cleanest result: a complete, rated window system with new seals and hardware.

During our free measure and quote, we check the condition of your existing windows and tell you which approach makes the most sense for each opening.

Compliance, BAL Ratings and Local Climate Considerations

Building rules and local conditions can add requirements that change the cost of double glazed windows. Australian Standards set requirements for window performance and safety glazing positions, and compliant products and installation matter for safety, insurance and resale.

In bushfire-prone parts of the Shoalhaven and Illawarra, including semi-rural areas like Nowra Hill and Worrigee, windows may need to meet a specific Bushfire Attack Level (BAL). A BAL rating can dictate frame, glass and screening requirements, which changes the specification and the price. We supply BAL-rated windows manufactured to meet relevant Bushfire Attack Level requirements, so let us know your property's BAL rating when you enquire.

Coastal exposure matters too. Salt air, strong sun and wind call for corrosion-resistant hardware and UV-stable materials, which is one reason uPVC frames are popular along the South Coast. Our windows are WERS rated, and we supply products to suit BASIX and NCC requirements.

Project Scope: Whole-Home Upgrades vs Targeted Replacements

How much of the house you upgrade at once has a direct effect on the total. Doing several openings in one visit shares the site setup, travel and access planning, which is usually more efficient than lots of small jobs.

If a whole-home upgrade isn't in the budget yet, start with the rooms that will make the biggest difference:

Street-facing bedrooms where traffic noise is a problem
West-facing living areas that cop the afternoon sun
Rooms with old windows that leak, rattle, stick or fog up with condensation

We're happy to help you plan a staged upgrade that fits your budget and renovation timeline. If you're still deciding whether the upgrade is worth it at all, our article on double glazed windows as an investment walks through the long-term benefits.

How RJV Industries Puts Your Double Glazing Quote Together

Itemised quote: each opening is listed with its style, glass package and installation allowances, so you can see where the cost comes from.

You can choose supply-only or full supply and install. To see the windows themselves, visit our double glazed windows Nowra page.

How to Prepare for Your Double Glazing Project

A little preparation keeps your quote accurate and helps avoid changes once work starts. Before you book a measure, it helps to know:

How many windows and doors you'd like to upgrade, and their rough sizes
Which rooms are the priority for noise, heat, cold or security
Any problems with existing windows, such as leaks, rot, condensation or sticking sashes
Whether your property has an assigned BAL rating
Any heritage, strata or estate rules about how the outside of the home can look
Whether future renovations might change any window openings

Write down your questions about glass, frames, ventilation and how the quote splits between supply and installation, and we'll work through them during the site visit. Our guide on how to choose the right windows for your home is a good starting point.

Frequently Asked Questions About Double Glazed Windows Cost

Can I get a rough cost per square metre for double glazing?

A per-square-metre figure is only a rough budgeting tool, because frame, glass, opening style and installation can make two windows of the same size cost very different amounts. For a figure you can rely on, book a free, no-obligation measure and quote with RJV Industries.

Is it cheaper to retrofit double glazed units into my existing windows?

Retrofitting can save on materials when your existing frames are in good condition and deep enough to take a sealed unit. The extra labour to adapt old frames can eat into those savings, so we assess each opening on site and recommend retrofit, secondary glazing or replacement case by case.

Does secondary glazing always cost less than full replacement?

Not always. Secondary glazing avoids changing the outside of the home, but it still needs careful fitting to perform. Whether it works out cheaper depends on the number of openings, access and preparation, and its performance won't match a new frame with a factory-sealed unit.

How much does professional installation add to the overall cost?

Installation covers removing old windows, fitting, sealing, trimming and checking operation, and it varies most with storeys, access and the condition of the existing openings. Our quotes show supply and installation separately, so you can see exactly what the labour covers.

How do I get a tailored quote from RJV Industries?

We'll measure each opening, check your existing windows and talk you through frame, glass and access options for your home in Nowra, Wollongong or anywhere across the Shoalhaven and Illawarra.

uPVC vs Aluminium Windows: Which Suits Coastal Homes?

Wed, 21 Oct 2026 18:08:16 GMT

For most coastal homes in Nowra, uPVC windows outperform standard aluminium windows on insulation, condensation and salt-air maintenance, while aluminium still wins on ultra-slim frames and very large openings. At RJV Industries , we supply and install uPVC double glazed windows from our base in Nowra across the Shoalhaven, Illawarra and South Coast, and this guide sets out the uPVC vs aluminium windows decision as fairly as we can so you can choose what suits your home.

Key Takeaways

Double glazed uPVC windows generally insulate better than standard aluminium and are less prone to condensation on the frame.
uPVC won't rust or corrode in salt air. Aluminium relies on its powder coat and regular rinsing to stay in good condition near the ocean.
Aluminium remains a strong choice for slim sightlines, very wide spans and homes where you want to match existing aluminium windows.
Our uPVC frames are designed and manufactured in the USA and WERS rated, and we offer supply-only or supply and install.

How This Guide Helps You Choose Between uPVC and Aluminium

This guide compares uPVC and aluminium window frames the way they actually perform in coastal NSW homes, from Culburra Beach and Kiama up to the northern Illawarra. Instead of focusing only on looks or upfront price, we compare thermal performance, condensation, noise, corrosion and maintenance.

We assume double glazing throughout, because most homeowners comparing frame materials today are also upgrading the glass. Timber comes up for context, but the main comparison is uPVC vs aluminium windows.

RJV Industries specialises in uPVC double glazed windows, so we're upfront about where we sit. We've still written this to help you make a sound decision whichever way you go.

What Are uPVC and Aluminium Windows? (And How They Differ)

uPVC windows use frames made from unplasticised polyvinyl chloride, a rigid material that insulates naturally, while aluminium windows use extruded metal frames that are usually powder coated. The difference in how each material handles heat is the root of most other differences between them.

uPVC frames are multi-chambered, often internally reinforced and UV-stabilised. They don't rust, rot or need repainting, and they're a poor conductor of heat.
Aluminium frames are strong, light and stable, and powder coating gives a durable, low-maintenance finish. Because aluminium conducts heat readily, it needs a thermal break to come close to uPVC's insulation.
Thermally broken aluminium separates the inner and outer frame with an insulating barrier. It performs much better than standard aluminium but is a more premium product.

Our uPVC frames are designed and manufactured in the USA, WERS rated, and supplied by a locally owned Nowra business.

Energy Efficiency and Double Glazing in Coastal Climates

uPVC double glazed windows generally deliver better whole-window insulation than standard aluminium, because the frame doesn't act as a bridge for heat and cold. Windows are one of the main paths for heat loss and gain in a home, so the frame matters as much as the glass.

Double glazing slows heat transfer with two panes and a sealed gap, which helps keep homes warmer in winter and cooler in summer.
uPVC frames insulate along their whole profile, so the frame keeps pace with the glass.
Standard aluminium conducts heat and cold through the frame, which can undermine good double glazing.
Thermally broken aluminium narrows the gap but still depends on careful glass selection.

Our windows are WERS rated, which means their energy performance is rated under the Window Energy Rating Scheme, so you can compare products on a like-for-like basis. For the glass side of the equation, see how double glazed windows are more energy efficient .

Condensation, Mould and Coastal Comfort

Aluminium frames are more prone to condensation than uPVC because the metal gets cold on winter nights and moisture in the indoor air settles on it. Along the Shoalhaven and Illawarra coast, where humid sea air meets cool nights, that shows up most in south-facing bedrooms and bathrooms.

Repeated condensation encourages mould, stains paint and plasterboard, and makes rooms feel damp.
uPVC double glazed windows keep the inside of the frame warmer and seal tightly, which noticeably reduces condensation on and around the window.
The difference is usually most obvious in bathrooms, bedrooms and rooms exposed to cool winter sea breezes.

If condensation is your main complaint, upgrading the worst-affected rooms first is often the most cost-effective starting point.

Coastal Durability, Salt Air and Maintenance

uPVC frames don't rust or corrode in salt air, while aluminium relies on its powder coat and regular care to hold up near the ocean. If you live within sight or sound of the water in places like Gerroa, Vincentia or Thirroul, that difference matters.

Aluminium: bare or damaged coatings can pit and corrode in coastal settings. Regular fresh-water rinsing, touch-ups and hardware care help keep frames looking good.
uPVC: no painting, sealing or corrosion protection. An occasional wash with mild soapy water and a hardware check is usually all it needs.
Timber: good insulation and a classic look, but it needs sanding, painting and close attention in coastal weather.

For busy households and holiday homes, uPVC's low upkeep is a real practical advantage. For simple care tips whichever frame you choose, read how to maintain your windows and doors for longevity .

Noise, Natural Light and Everyday Living

Both uPVC and aluminium windows can reduce outside noise when paired with good double glazing, and uPVC frames combined with tight seals are particularly effective. The frame material has much less effect on natural light than the glass size and window design.

Double glazing in either frame cuts traffic, dog and neighbourhood noise compared with single glazing.
uPVC frames with compression seals help limit sound leaking around the sash.
Aluminium's slimmer frames can let in slightly more light for the same opening, which some designers prefer.
In most family homes, slightly wider uPVC frames still let in plenty of light while improving comfort and quiet.

Noise is a big topic on its own. Our article on how retrofitted double glazing reduces noise pollution goes into more detail.

Style, Design Flexibility and Matching Existing Windows

Aluminium suits slim, minimalist designs and very wide sliding doors, while uPVC suits homeowners who want low maintenance and a range of colours and finishes. For many people, matching the rest of the house matters as much as performance.

Aluminium's strength lets it carry large panes in slim frames, which suits contemporary coastal builds and big glass doors.
uPVC now comes in a range of colours and finishes, not just white, and suits both traditional and modern homes.
uPVC profiles are generally a little chunkier than aluminium, although modern profiles have narrowed the gap.
If your home is full of aluminium windows, some owners stick with aluminium on the street side for consistency.
Mixing materials is common: upgrading bedrooms and living areas to double glazed uPVC while keeping aluminium in less-used rooms.

When uPVC Makes More Sense – And When Aluminium Wins

uPVC usually makes more sense for coastal homes focused on comfort, energy efficiency and low maintenance, and aluminium usually wins where slim frames or very wide spans are the priority. There's no single right answer, so weigh up what matters most to you.

uPVC double glazed windows tend to suit:

Homes exposed to salt air and sea breezes
Households wanting lower heating and cooling bills
Homes near busy roads or noisy neighbours
Owners who don't want to repaint or treat frames

Aluminium windows tend to suit:

Architectural designs that call for ultra-slim frames
Very large openings and commercial-style glazing
Estates or designs that specify aluminium
Matching a home that's already all aluminium

Don't decide on looks or upfront price alone. Think about comfort, cleaning, condensation and how often you open and close each window over many years.

FAQs: uPVC vs Aluminium Windows in Coastal NSW

Do uPVC windows discolour or become brittle in strong Australian sun?

Modern uPVC frames are UV-stabilised to handle strong sun. With basic care, such as an occasional wash with mild soapy water and no harsh solvents, they keep their colour and finish well.

Can I replace only some of my existing aluminium windows with uPVC?

Yes. Many homeowners start with the least comfortable rooms, usually bedrooms and living areas, and upgrade the rest later. We can suggest frame colours and styles that keep the home looking consistent from the street.

Are uPVC frames strong enough for larger openings like sliding doors?

Modern uPVC frames for doors and larger windows are reinforced to carry double glazed units when installed correctly. For very wide spans, we'll tell you honestly whether uPVC or aluminium is the better fit.

Will upgrading to double glazed uPVC windows help with summer heat as well as winter cold?

Yes. Insulating frames and double glazing reduce heat gain in summer and heat loss in winter, and glass choices such as Low-E can be matched to each window's orientation.

How do I get an accurate comparison quote between uPVC and aluminium windows?

Compare like for like: the same sizes, opening styles, glass and hardware, plus long-term maintenance as well as upfront price.

BAL Rated Windows: A Guide for Bushfire-Prone Homes

Wed, 21 Oct 2026 18:06:30 GMT

BAL-rated windows in Nowra are complete window systems designed to meet a property's Bushfire Attack Level under Australian Standard AS 3959. If you're building or renovating on bushfire-prone land in the Shoalhaven, Illawarra or South Coast, that rating decides what windows you can install. At RJV Industries , we supply BAL-rated windows from our Nowra base, and this guide explains what BAL ratings mean, how yours is determined and what to ask before you buy.

Key Takeaways

A Bushfire Attack Level (BAL) is a site-specific rating, from BAL-LOW to BAL-FZ, set out in AS 3959.
BAL-rated windows are whole systems: frame, glass, seals, screens and hardware. Special glass alone doesn't make a window BAL rated.
Requirements get stricter at each level, affecting materials, glazing, screening and sometimes window size and style.
Your certifier or council confirms what's required for your project, so get your BAL rating confirmed early.
We supply BAL-rated windows manufactured to meet relevant Bushfire Attack Level requirements. Call RJV Industries on 0457 431 660 for a free, no-obligation measure and quote.

What Is a Bushfire Attack Level (BAL)?

A Bushfire Attack Level is a rating of how severely a building site could be exposed to bushfire attack, from embers and radiant heat through to direct flame contact. The system is set out in AS 3959, the Australian Standard for construction in bushfire-prone areas.

A site's BAL is based on the type of surrounding vegetation, its distance from the building, the slope of the land and expected fire behaviour. The levels, from lowest to highest exposure, are:

BAL-LOW: very low risk, no specific bushfire construction requirements
BAL-12.5: ember attack and low radiant heat
BAL-19: increasing ember attack and radiant heat
BAL-29: higher radiant heat and ember attack
BAL-40: high radiant heat with possible flame exposure
BAL-FZ (Flame Zone): direct exposure to flames from the fire front

In NSW, councils and certifiers use the BAL during planning and approval to set minimum standards for windows, doors, cladding, decks and other parts of the home.

How BAL Ratings Are Determined for Your Property

A property's BAL is set by a BAL assessment, a site-specific report prepared by a bushfire consultant or other suitably qualified professional. They look at the vegetation around your property, measure distances and slope, and apply the method in AS 3959 to assign the rating.

Across the Shoalhaven, Illawarra and South Coast, many semi-rural and bush-fringe areas, including Nowra Hill, Worrigee, Berry and the Kiama hinterland, are mapped as bushfire prone, so BAL assessments are common for new builds, extensions and major renovations. Your council's bushfire prone land map shows whether your property is affected.

The usual process looks like this:

Check your council's bushfire prone land map.
Engage a qualified professional for a BAL assessment if one is needed.
Receive a BAL report confirming your rating.
Your designer and certifier apply AS 3959 and NSW planning rules to set construction requirements.

Get your BAL confirmed early in the design stage, before you choose windows or sign quotes, to avoid expensive changes later. Always confirm specific requirements with your certifier or council.

Understanding the BAL Rating System and Window Requirements

Windows are one of the most vulnerable parts of a home during a bushfire, which is why window requirements tighten as the BAL rises. At higher levels, the rules affect materials, glazing, screening, seals and sometimes how windows can be configured.

From BAL-12.5 upwards, windows and glazed doors generally need to limit ember entry through gaps and openable sashes. As radiant heat exposure increases, the glass and frame must also hold up under higher temperatures without failing early.

BAL compliance is about the whole window system working together: frame, glazing, seals, screens and fixings. A window that suits BAL-12.5 in a Nowra suburb may not be acceptable at BAL-40 on a heavily vegetated ridge, so your glass, frame, window style and even window size choices all depend on your rating.

What Changes for Windows at Each BAL Level?

Window requirements become progressively more demanding at each Bushfire Attack Level. The summary below is general guidance only, and your certifier confirms the exact requirements for your project.

BAL-LOW: no specific bushfire requirements for windows.
BAL-12.5 and BAL-19: the focus is on stopping embers. Openable windows typically need ember screens in corrosion-resistant mesh, and frames need to be well sealed. Glazing requirements step up as the level rises.
BAL-29: radiant heat becomes more significant, so glass and frame specifications become more important and tighter construction requirements apply.
BAL-40: exposure is high enough that windows usually need to be a system specifically manufactured and tested for this level, and shutters may be part of the solution.
BAL-FZ: highly specialised, tested systems or protective shutters are typically required. Don't assume any standard product will comply, and follow your certifier's guidance closely.

What Makes a Window BAL Rated?

A window is BAL rated when the complete unit is manufactured to meet a nominated Bushfire Attack Level under AS 3959, with documentation to show it. It's the whole assembly, not just the glass, that earns the rating.

Frames: must suit the required level, accept screens where needed and minimise gaps where embers could get in.
Glazing: the glass type and thickness must match the BAL. Toughened glass is often specified because it handles heat stress better than standard annealed glass.
Seals and screens: tight seals and ember screens on openable sashes help stop embers getting inside.
Installation: a BAL-rated window has to be installed correctly into the wall, with gaps, flashings and fixings done properly, to perform as intended.

For general guidance on choosing quality units, our guide to selecting durable double glazed windows covers what to look for in frames, glass and hardware.

How BAL Rated Windows Fit into Everyday Comfort

BAL-rated windows don't have to mean giving up everyday comfort. A well-specified double glazed BAL window still slows heat transfer through the glass, helping keep homes warmer in winter and cooler in summer in the South Coast climate.

That matters on semi-rural blocks around Nowra and the Shoalhaven, where homes often face hot westerly summers and cool winter nights. Double glazing can also cut outside noise from roads, farm machinery or neighbouring properties.

The key is to specify the window for your BAL first, then choose the style, glass and finish that best suit your comfort goals within those rules.

Working with a Supplier: What to Ask About BAL Compliance

Start every window conversation with your confirmed BAL rating, because it shapes every recommendation that follows. Useful questions to ask any supplier include:

Are these windows manufactured to meet my specific BAL rating under AS 3959?
Which parts of the system (frame, glazing, screens, seals and hardware) are designed for bushfire performance?
What documentation can you provide for my certifier?
Which window styles (fixed, awning, casement, sliding) work best at my BAL level?
How are screens and seals supplied, installed and maintained?

Also check that your supplier understands local conditions, such as salt air on the coast and humidity, as well as NSW planning requirements that sit alongside AS 3959. We're happy to talk you through the options for your property.

FAQs about BAL Rated Windows

Do all homes in the Shoalhaven and South Coast need BAL-rated windows?

No. BAL requirements generally apply only to properties mapped as bushfire prone and to work that needs approval. Many semi-rural and bush-adjacent areas in the region are mapped, so check your council's bushfire prone land map or ask your certifier whether a BAL assessment is needed.

Can I upgrade my existing windows to meet a higher BAL rating?

Often, yes. Replacing existing windows with new BAL-rated units can improve bushfire performance, but the whole opening, the surrounding construction and current rules all need to be considered. Talk to your certifier and to us about what's practical for your rating.

Are all double glazed windows automatically BAL compliant?

No. Double glazing alone doesn't make a window BAL compliant. The frame, glazing, seals, screens and hardware must be manufactured together to meet your Bushfire Attack Level, so always confirm a product suits your specific rating.

Will BAL requirements limit the size or style of my windows?

They can at higher levels, where the size, type and position of openable windows may be restricted. Work early with your designer, certifier and window supplier to balance compliance with light, ventilation and views.

Who has the final say on whether my windows meet BAL requirements?

Your certifier is generally responsible for confirming compliance for the project, using the product documentation your supplier provides. RJV Industries can supply product information for your certifier and work alongside your builder and designer, so give us a call on 0457 431 660 to talk through your project.

Double vs Triple Glazing: Which Do Coastal NSW Homes Need?

Wed, 21 Oct 2026 18:03:19 GMT

For most homes in coastal NSW, well-specified double glazing gives all the comfort and energy performance you need, and triple glazing only earns its place on exposed, very noisy or ultra-low-energy builds. At RJV Industries, we supply and install uPVC windows with both double and triple pane glass packages from our base in Nowra , and this guide explains the double vs triple glazing decision for Shoalhaven, Illawarra and South Coast homes.

Key Takeaways

Upgrading from single to double glazing is where the big comfort gains happen. Adding a third pane gives smaller extra gains in a mild coastal climate.
Triple glazing can make sense for exposed escarpment or clifftop sites, homes on very busy roads, and builds chasing the lowest possible energy use.
U-value measures heat transfer, SHGC measures solar heat coming through, and VT measures visible light. Choose glazing by orientation, shading and noise, not pane count alone.
We offer three WERS rated glass packages: Premium (double pane), Advanced (triple pane) and Advanced Max (triple pane).
Call RJV Industries on 0457 431 660 for a free, no-obligation measure and quote.

Double and Triple Glazing: The Basics

Double glazing uses two panes of glass separated by a sealed, insulating gap, while triple glazing uses three panes and two gaps. Gas fill, spacers, coatings, frame material and installation quality matter just as much as the number of panes.

Many older homes around Nowra, Kiama and Wollongong still have single glazed aluminium or timber windows. They lose heat in winter, let in unwanted heat in summer and do little to block noise.

Double glazing: two panes with a sealed gap, often argon filled, giving a major step up from single glazing.
Triple glazing: three panes and two gaps for extra thermal and acoustic performance. The units are heavier and thicker, and let in slightly less light.

Our three glass packages are:

Premium: double pane, one Low-E and one clear pane, argon filled
Advanced: triple pane, one Low-E and two clear panes, argon filled
Advanced Max: triple pane, two Low-E panes and one clear pane, argon filled

If you're still on single glazing, our comparison of single vs double glazed windows is a useful first read.

How Window Energy Ratings Work: WERS, U-Value, SHGC and VT

Window energy ratings describe how a complete window, frame and glass together, handles heat and light, and they let you compare products on a level playing field. Our windows are WERS rated, meaning their energy performance is rated under the Window Energy Rating Scheme.

U-value: how readily heat passes through the whole window. Lower is better insulation. Triple glazing usually lowers the U-value further than double glazing.
SHGC (solar heat gain coefficient): the share of the sun's heat that gets through. A lower SHGC helps limit summer overheating on west and east-facing glass, while a higher SHGC can welcome winter sun on north-facing windows.
VT (visible transmittance): how much daylight gets through. Extra panes and some Low-E coatings reduce VT slightly.

If you're building or doing a major renovation in NSW, your BASIX certificate or energy assessment will usually list target U-value and SHGC figures for your windows. Bring them along and we'll match them against our Premium, Advanced and Advanced Max packages. All three are compared on our glass options page.

Thermal Performance in a Mild Coastal NSW Climate

In the Shoalhaven, Illawarra and South Coast, double glazing with Low-E glass and argon fill usually delivers more than enough thermal performance, because winters are mild compared with alpine or tableland areas. Triple glazing is designed for cold climates where heating loads are high, so its extra benefit shrinks here.

The biggest gain comes from replacing single glazing. Moving from double to triple glazing improves insulation again, but in our climate that extra step is smaller, especially when the home already has good roof and wall insulation and sensible eave shading.

There's also a trade-off to manage. Triple glazing and extra Low-E coatings can lower SHGC and VT, which may slightly reduce the free winter warmth and daylight coming through north-facing living room windows. For most retrofits in places like Berry, Gerringong or Huskisson, the Premium double glazed package gets the balance right.

Noise Reduction, Comfort and Condensation

Both double and triple glazing reduce outside noise and condensation compared with single glazing, and the difference between the two is usually subtle in suburban settings. Glass thickness, laminated glass and good seals often matter more for noise than the number of panes.

A well-specified double glazed unit, especially with panes of different thicknesses or laminated glass, can perform very well against traffic and neighbourhood noise.
Triple glazing adds another barrier and may help on sites right beside the Princes Highway, a rail line or an exposed, windy clifftop.
Both options keep the inner glass warmer than single glazing in winter, which reduces condensation, although ventilation and humidity control still matter in coastal homes.

For more on noise, read how retrofitted double glazing reduces noise pollution .

Frames, Natural Light and Design Choices

The frame and the installation are just as important as the glass, because a poorly sealed or highly conductive frame undermines any glazing. uPVC frames pair well with both double and triple glazed units in coastal conditions.

uPVC frames don't conduct heat the way standard aluminium does, they handle salt air well and they seal tightly around the glass.
Triple glazed units are heavier and thicker, so they need frames and hardware designed to carry them.
Slightly deeper frames can affect sightlines a little, so careful window sizing and placement help keep rooms bright.
Eaves, external shading and good window furnishings work alongside the glazing to manage heat without losing light.

When Is Triple Glazing Worth It vs When Double Glazing Is Enough?

Double glazing is enough for most coastal NSW homes, and triple glazing is worth it mainly where a site or design brief calls for performance beyond the norm. Triple glazing costs more upfront, so it pays to weigh it against other upgrades such as insulation and shading.

Double glazing is usually enough when:

You're building a standard new home in Nowra or Wollongong
You're replacing single glazed windows in an existing home
Noise exposure is moderate and the home has reasonable insulation

Triple glazing may be justified when:

An architect-designed, very airtight home is targeting very low heating and cooling loads
An exposed rural, escarpment or coastal site faces strong winds
Acoustic requirements are strict, or you want maximum quiet on one noisy elevation
Large areas of glass or difficult orientations make the extra performance count

Bring your plans and BASIX or energy assessment to us, and we'll compare double and triple glazed options against your targets.

FAQs: Double and Triple Glazing in Coastal NSW

Can I mix double glazed and triple glazed windows in the same home?

Yes. A common approach is triple glazing on the noisiest or most exposed side of the house and double glazing elsewhere. As long as the windows look consistent and your compliance targets are met, combining both works well.

Will upgrading from single glazed windows always improve my BASIX outcome?

Replacing single glazing with energy-rated double or triple glazing usually helps, but the result also depends on orientation, shading, insulation and window sizes. Check with your energy assessor before finalising your window specification.

Do triple glazed windows make rooms too dark?

Triple glazing and some Low-E coatings let through slightly less visible light than clear glass, but good window placement, sensible opening sizes and light interior finishes keep rooms bright.

How do I know which U-value and SHGC I actually need?

Check your BASIX certificate or energy assessment, which usually sets window performance targets. Bring those figures to us and we'll match them to the most suitable Premium, Advanced or Advanced Max package.

What maintenance do double and triple glazed windows need near the coast?

Clean the frames and glass regularly, keep drainage slots clear and check the seals every year. Fogging between the panes can point to a seal issue, so let your installer know. For a free, no-obligation measure and quote, give RJV Industries a call on 0457 431 660.

Composite Siding vs Weatherboard: A Coastal Cladding Guide

Wed, 21 Oct 2026 18:01:53 GMT

Composite siding and timber weatherboards both give a home that classic board-and-shadow-line look. The big difference is upkeep: timber needs regular painting and checks for rot, while a pre-finished composite like Everlast never needs painting or sealing. At RJV Industries , we supply and install Everlast Advanced Composite Siding from our base in Nowra , and this guide compares composite siding vs weatherboard (and fibre cement) for re-clads and new builds across the Shoalhaven, Illawarra and South Coast.

Key Takeaways

Composite siding is a low-maintenance alternative to timber weatherboards, especially in coastal areas where salt, humidity and UV break down paint quickly.
Timber weatherboards have a classic Australian look but need ongoing painting or staining and checks for rot and swelling.
Fibre cement sits between the two: stable and rot-resistant, but still reliant on paint that wears over time.
The right choice depends on your budget, how much maintenance you're willing to do, your streetscape and your exposure to the coast.

How Composite Siding and Weatherboards Differ (Quick Comparison)

Composite siding and timber weatherboards differ mainly in what they're made of, how they handle moisture and how much maintenance they need. Neither is better in every case. A homeowner in Nowra who never wants to repaint will lean towards composite, while someone restoring a cottage in Berry may want real timber for heritage character.

Material: timber weatherboards are solid wood. Composite siding is an engineered board with its finish built in. Fibre cement is made from cement, sand and cellulose fibre.
Maintenance: timber needs regular painting, staining or oiling. Everlast composite siding never needs painting or sealing. Fibre cement needs repainting over time.
Moisture: timber absorbs and releases moisture, so it can swell, shrink and rot if the finish fails. Everlast won't rot, swell or peel like timber. Fibre cement is stable but still depends on its paint and detailing.
Coastal exposure: in places like Kiama, Shellharbour and Ulladulla, salt and wind wear finishes down faster, which favours low-maintenance options.

What Are Timber Weatherboards, Composite Siding and Fibre Cement Cladding?

Timber weatherboards, composite siding and fibre cement are the three most common lightweight cladding types on homes in coastal NSW, and each one sits on the outside of a layered wall system.

Timber weatherboards are overlapping horizontal boards in treated pine or hardwood, found on everything from Federation cottages to mid-century beach houses. People love their grain and shadow lines, and they can be repainted any colour.
Composite siding is a manufactured board designed to look like painted timber with a factory finish. Everlast Advanced Composite Siding, which we supply and install, won't rot, swell or peel like timber and never needs painting or sealing.
Fibre cement cladding comes as boards or sheets, usually primed and painted on site. It resists rot and insects and suits Hamptons and modern coastal styles.

Whichever you choose, cladding is weather resistant rather than waterproof. It works with the framing, insulation, building wrap, flashings and a drainage cavity behind it, and those layers deal with any water that gets past the boards.

Looks and Street Appeal: Style Differences

Cladding shapes how a home sits in its street, so the look often matters as much as the performance.

Timber weatherboards: natural grain and warmth that's hard to replicate. They suit heritage towns like Berry, Milton and Gerringong, and can be stained to show the grain or painted for a beach house look.
Composite siding: Everlast is designed to look like painted weatherboards without the repainting. A factory finish keeps the colour consistent across the facade, and a range of profiles and colours suits coastal and semi-rural designs.
Fibre cement: weatherboard profiles, grooved boards and flat panels are popular on new builds, often paired with brick or render for contrast.

Think about your street (older town centre or new estate), any council or estate design rules, and how the finish will look in ten years, not just on day one.

Maintenance and Painting: How Much Work Is Involved?

Long-term care is where composite siding vs weatherboard shows the biggest difference for Shoalhaven and Illawarra homeowners.

Timber weatherboards

Regular repainting or staining to cope with UV, salt spray and rain, more often close to the water
Scraping, sanding and spot repairs where paint flakes
Ongoing checks for rot at board ends, around windows and doors, and near decks

Everlast composite siding

Never needs painting or sealing, because the finish is built into the board
Usually just a gentle wash to remove dust, cobwebs and salt
Won't rot, swell or peel like timber, reducing the risk of hidden damage

Fibre cement

Relies on primer and paint, which need renewing as they fade and chalk in coastal sun
Joint sealants and flashings need checking over time

Be honest about whether you'll do weekend painting yourself or pay painters, because that ongoing cost adds up over the life of the home.

Moisture, Rot and Coastal Weather Performance

Coastal homes face wind-driven rain, humidity and salt air, and timber is the cladding most at risk when its paint fails. Here's how each option handles those conditions.

Timber: absorbs moisture once the paint breaks down, leading to swelling, cupping, cracking and rot. Risk is highest at the bottoms of walls, near garden beds and on shady southern sides that stay damp.
Composite siding: Everlast won't rot, swell or peel like timber, a clear advantage on coastal and lakeside properties around Jervis Bay and Lake Illawarra.
Fibre cement: dimensionally stable and not prone to rot, but it depends on correct painting, joints and detailing.

Whatever the board, the wall still needs proper flashings, wrap and a drainage cavity, installed by people who understand local wind and rain.

Cost Considerations: Beyond Just the Price Per Board

The cost of cladding depends on far more than the boards themselves, so it pays to look at the whole job and the ongoing upkeep rather than the material price on day one.

Cost factors for any cladding:

The size and height of the home, how complex the facade is and how easy the site is to access
Removing and disposing of old cladding on a re-clad
Wrap, battens, flashings, fixings and trims behind the boards
Scaffolding on two-storey or sloping sites

Material-specific factors:

Timber: boards plus primer and paint or stain, often installed and painted by separate trades, then repainted again over the life of the home.
Composite siding: typically a higher upfront cost, but Everlast is pre-finished, so there's no painting or sealing on site or down the track.
Fibre cement: boards and accessories, cutting with dust controls, then a full paint system on site.

We give a tailored measure and quote that covers everything, so you can compare options on whole-of-life value.

Installation, Retrofits and New Builds

All three cladding types suit both new builds and re-clads, but the work involved differs depending on the home.

Re-cladding older timber homes: common across the Shoalhaven and South Coast. It often means repairing framing, replacing damaged boards and updating wraps and flashings, and it's a good chance to upgrade insulation too.
Composite siding: Everlast siding suits new builds and re-clads where owners want to cut future upkeep, and pre-finished boards mean no painting stage.
Fibre cement: widely used on new builds for straight, modern facades, sometimes mixed with brick veneer or render.

Whichever material you choose, correct installation to the National Construction Code, Australian Standards and the manufacturer's instructions decides how well and how long the cladding performs.

Energy Efficiency, Comfort and Acoustics

Lightweight cladding plays a smaller role in a home's thermal performance than the insulation and windows do. Wall insulation sits behind the boards, so comfort depends more on what's in the wall cavity than on whether the outside is timber, composite or fibre cement.

Where cladding does matter is in how well the wall manages moisture. A well-detailed cavity and membrane help walls dry out after coastal storms and reduce the risk of condensation inside the frame.

None of these lightweight claddings blocks sound like brick. If noise or comfort is your priority, windows usually make a bigger difference than the cladding. Our article on the benefits of double-glazed windows explains why, and a re-clad is a natural time to upgrade them.

Environmental and Sustainability Considerations

Each cladding type comes with environmental trade-offs, and no option wins on every measure.

Timber: renewable when responsibly sourced and repairable in small sections, but regular repainting means ongoing use of coatings.
Composite siding: the aim is a long service life without repainting, which reduces the coatings and labour used over time. Check product literature for detailed lifecycle information.
Fibre cement: energy-intensive to make, but durable, with a long track record in Australian homes.

Balance durability, maintenance and resource use, and ask for product documentation if sustainability is a deciding factor for your project.

Which Exterior Cladding Suits Your Home and Location?

The best cladding for your home depends on where it sits, the style you want and how long you plan to stay.

Exposed coastal suburbs such as Culburra Beach, Mollymook and Gerroa: composite siding avoids the paint cycle and rot risk that salt and wind bring.
Heritage streetscapes such as Berry, Milton and Gerringong: timber weatherboards may be preferred or required, so check with council first.
New estates and modern designs: composite and fibre cement are often combined for texture and contrast.

If you're staying long term, lifetime maintenance matters more than upfront price. Talk to your designer, builder and cladding supplier early to avoid costly changes once construction starts.

Frequently Asked Questions

Is composite siding suitable for bushfire-prone areas on the South Coast?

It depends on the specific product's documentation and your site's Bushfire Attack Level (BAL). Check the manufacturer's information and confirm compliance with your designer, builder or certifier before choosing cladding for a BAL-rated site.

Can I mix composite siding with other exterior cladding materials?

Yes. Many homes combine composite siding with brick, render or fibre cement panels. Keep colours, proportions and junction details consistent, and make sure flashings at the transitions are detailed properly.

Do I need to remove my old timber weatherboards to install composite cladding?

Often, yes, so the framing, wrap, insulation and cavity can be checked and brought up to current standards, but it depends on the condition of your home. We'll advise on site during the measure and quote.

How do I clean and care for Everlast Advanced Composite Siding?

A gentle wash with water and a soft brush or cloth removes dust, cobwebs and salt. Avoid harsh abrasives. Because Everlast never needs painting or sealing, care is about keeping it clean, not recoating it.

When in my project should I decide on external cladding?

Early in the design stage, so that wall build-ups, window and door details and colour schemes can be coordinated. RJV Industries is happy to help at the planning stage. Give us a call on 0457 431 660 to talk about cladding and windows for your home.

Tom's uPVC Double Glazed Windows Woonona Story

Tue, 26 May 2026 20:02:00 GMT

I'll be honest. I went into this process as a fairly sceptical comparison shopper. We have a two-storey home in Woonona and I had three companies come out and quote on replacing all our windows with uPVC double glazing. I did my homework, I asked a lot of questions, and I made a spreadsheet. RJV Industries Windows won the job not on price alone, but on the quality of the conversation and the clarity of what they were proposing. If you're comparing quotes for double glazed windows in Wollongong and trying to work out who to trust , this is what I learned. We ended up with a full set of uPVC double glazed windows throughout the house and it was absolutely the right call.

Comparing window replacement quotes is more complex than most home improvement projects because the product specifications can vary significantly between companies. uPVC frame composition, glass unit specifications, spacer bar type, and installation methodology all affect long-term performance. For a two-storey home with 24 windows across multiple aspects, getting this right mattered. Research suggests that correctly specified and installed uPVC double glazed windows can deliver energy savings of between 20% and 30% on heating and cooling costs annually, which over a decade adds up to a meaningful return on investment.

The Problem in Detail

Our home was built in the late 1990s and still had its original aluminium single-glazed windows throughout. Two storeys, north-facing upstairs bedrooms that were great in theory but hot in practice, and a south-facing lower level that was draughty and cold in winter. The windows were operational but inefficient, and the thermal split between the two floors made climate control genuinely difficult to manage.

I'd been thinking about double glazing for a couple of years. The trigger was a neighbour's renovation where they'd replaced windows and I could see the difference in how their home performed. I started getting quotes and quickly realised that not all proposals were equal. Some companies were quoting aluminium double-glazed units, others uPVC; some included low-E glass as standard, others as an upgrade. It was harder to compare apples with apples than I'd expected.

How RJV Industries Windows Responded

RJV Industries Windows stood out from the first site visit. They were thorough, assessed each window individually rather than treating the house as a uniform job, and explained what they were recommending and why in terms I could actually evaluate. Read more about our team and the level of detail we bring to every quoting process.

They walked me through their full window range and helped me understand the specification differences between options rather than just telling me what to buy. That kind of transparency is exactly what you want when you're spending a significant amount on a home upgrade. They also took the time to explain how the performance of uPVC double glazed windows on a two-storey home differs from a single-storey property, particularly in terms of thermal stratification between floors. That level of detail was something the other companies hadn't touched on.

The quote was detailed, clearly laid out room by room, and was competitive against the other proposals I had on the table. There was no pressure to decide quickly and no sense that anything was being obscured.

The Solution and Outcome

RJV Industries Windows replaced all 24 windows across both levels with uPVC double glazed windows, with low-E glass specified for the north-facing upstairs windows and acoustic laminated glass for the two bedrooms closest to the street. The installation was completed over three days with a crew that communicated clearly throughout and left the home in good order each evening.

The thermal balance between the two floors has improved significantly. The upstairs bedrooms no longer overheat in summer and the lower level is noticeably warmer in winter without the draughts we'd grown used to. The noise reduction on the street-facing rooms has also been a genuine quality-of-life improvement, particularly for the kids' bedrooms. Our power bills in the first full year after installation dropped by around 25% compared to the year before, which aligned closely with what RJV Industries Windows had projected.

Looking back, the comparison shopping process was worth doing. But I'd go straight to RJV Industries Windows next time without hesitation.

What Tom Would Tell Others

If you're getting multiple quotes, make sure you're comparing the same specifications. Ask each company about glass type, frame composition, spacer bar material, and installation methodology. A lower quote might mean a lower-spec product. RJV Industries Windows won our job because they explained what they were quoting and why it was the right choice for our home.

Steve's New Build Double Glazed Windows Upgrade in Wollongong

Tue, 26 May 2026 20:00:14 GMT

When we built our new home in Shellharbour, the builder's standard window package was aluminium single glazed. It's what most new builds in the area come with as the base spec, and at the time we didn't question it much. But about six months in, after our first summer in the house, it became clear that the large north and west-facing windows were making it genuinely difficult to keep the main living area comfortable. A friend who'd recently had double glazed windows installed in Wollongong pointed us toward RJV Industries Windows, and after a good conversation about what we actually needed, we ended up upgrading to uPVC double glazed windows throughout. It was a decision that changed how the whole house performed.

New homes in the Illawarra region are often designed with large glazed areas to maximise light and views, but single glazed aluminium windows work against that comfort goal by allowing significant heat transfer in summer and heat loss in winter. According to energy efficiency research, windows can account for up to 40% of a home's heating and cooling energy loss. In a new build, upgrading to uPVC double glazing from the outset is one of the most impactful changes you can make to long-term running costs.

The Problem in Detail

Our home was only six months old but the thermal performance of the windows was already a real frustration. The north-facing lounge and the open-plan kitchen and dining area, which had large west-facing glass panels, were extremely hot by mid-afternoon in December and January. The air conditioning was running for hours each day to compensate, and the bills reflected it.

I'd started reading about double glazing and the difference between standard aluminium frames and uPVC when it came to thermal bridging. Aluminium conducts heat readily, which means even double-glazed units in aluminium frames can lose thermal efficiency through the frame itself. uPVC frames don't have that problem, which is why they're used as the standard in energy-efficient construction across Europe and increasingly across Australia.

How RJV Industries Windows Responded

RJV Industries Windows came highly recommended and from the first meeting it was clear they understood new builds specifically. They walked through our house, assessed each room's orientation and glazing, and gave us a clear breakdown of where the biggest performance gains could be made. Read more about there team and the expertise they bring to residential window upgrades across the Illawarra.

They recommended uPVC double glazed windows with a specific low-E glass coating for the north and west-facing areas of the home, and explained how different glass options perform differently depending on orientation and function. The approach was methodical and evidence-based rather than just picking one product and quoting it across the whole house. That gave us a lot of confidence we were getting the right solution rather than just an expensive one.

The quote was detailed and clearly explained.That extra attention to detail was reassuring.

The Solution and Outcome

RJV Industries Windows replaced all windows in the home with uPVC double glazed window , with low-E glass specified for the north and west-facing windows and standard double glazing for the remaining aspects. Installation took two days and was completed without any damage to the recently finished interior.

The improvement in thermal comfort was immediate and significant. The living areas now hold a stable temperature through even the hottest Shellharbour afternoons, and the air conditioning runtime has dropped dramatically compared to our first summer. We're also finding the house genuinely warm in winter without the heater needing to work as hard, which is a bonus we hadn't fully anticipated.

The uPVC frames look clean and modern against the new build exterior. We've had several neighbours ask who did our windows after noticing how comfortable our house looks to live in even on hot days.

What Steve Would Tell Others

If you're building new or have recently moved into a new home with standard aluminium single glazed windows, I'd strongly suggest getting a quote for uPVC double glazing before you spend another summer fighting your air conditioner. The running cost savings alone will justify the upgrade over a few years, and the day-to-day comfort difference is significant from day one.

Mel's Corrimal Double Glazed Windows Story

Tue, 26 May 2026 19:59:21 GMT

Honestly, I wasn't even thinking about new windows until my neighbour mentioned she'd just had hers done. We'd lived in our 1990s townhouse on Corrimal's main road for eight years and the bedroom noise was just something we'd accepted as part of life. But after she described how quiet her place was at night after getting double glazed windows in Wollongong installed by RJV Industries Windows, I thought it was worth at least making a call. That call turned into a visit, which turned into one of the better home decisions we've made. If you're researching uPVC double glazed windows in the Illawarra and wondering whether it's worth it, this is my experience.

Our townhouse sits about 15 metres from a fairly busy stretch of road. During the day it's manageable, but from early morning the traffic builds and by 7am on weekdays the bedroom is loud enough to wake a light sleeper. We'd tried thick curtains, a white noise machine, even rearranging the furniture to move the bed further from the windows. None of it made a real dent. Acoustic performance of double glazed windows can reduce external noise by up to 35 decibels compared to single glazed, which in practical terms is the difference between a noisy street outside and a quiet bedroom inside.

The Problem in Detail

It wasn't just the noise. The bedroom windows also faced east, which meant winter mornings brought condensation across every pane. By mid-morning we'd often wipe the sills down. In summer the rooms heated up quickly and held warmth late into the evening, making it hard to sleep without the air conditioner running all night. The windows themselves were the original aluminium frames from when the townhouse was built, single glazed and starting to show their age.

I'd been curious about double glazing for a while but assumed it was more of a cold-climate solution and wasn't sure it was relevant in Wollongong. After speaking with RJV Industries Windows I quickly understood that thermal comfort and acoustic performance are relevant year-round on the Illawarra escarpment, and that uPVC frames specifically were a better long-term investment than standard aluminium replacements.

How RJV Industries Windows Responded

From the first conversation, RJV Industries Windows were easy to deal with. They came out for a site visit, had a look at the bedroom windows and the rest of the townhouse, and gave us a clear picture of what was involved. They didn't push us to do every window in one go, which I appreciated. Find out more about our approach and why we take the time to tailor solutions to what each homeowner actually needs.

They explained that the bedrooms were the logical priority given our noise and condensation issues, and outlined how uPVC double glazed windows with an appropriate glass specification would address both problems. There transparency made the whole thing feel very straightforward.

The quote came through quickly and was itemised clearly. There were no hidden costs and no pressure to upgrade beyond what was actually useful for our situation. RJV Industries Windows answered every follow-up question I had promptly and without making me feel like I was wasting their time.

The Solution and Outcome

RJV Industries Windows replaced the four bedroom windows with uPVC double glazed windows using acoustic laminated glass. The installation took less than a day and the team left the place clean and tidy. Custom-measured frames, no fuss, done properly.

The first night after installation was genuinely surprising. The room was noticeably quieter even with traffic passing outside. My partner, who had been a light sleeper for years, slept through to the alarm for the first time in longer than we can remember. The condensation issue is completely resolved, and the room now holds a comfortable temperature overnight without the air conditioner.

We've since had RJV Industries Windows back to quote on the living area windows. Once you experience the difference in even one room, you want it throughout the house.

What Mel Would Tell Others

Don't dismiss double glazing as something that's only relevant in colder climates. In Wollongong, the combination of road noise, condensation, and thermal comfort makes uPVC double glazed windows a genuinely useful upgrade for everyday living. Get a quote and see what it would mean for the specific rooms causing you problems.

Brendan's uPVC Double Glazed Windows Coastal Reno

Tue, 26 May 2026 19:58:24 GMT

Living in a weatherboard home 200 metres from the beach in Thirroul sounds like a dream until you factor in the noise, the wind, and the salt air doing its best to strip every surface in the house. Our aluminium windows were original to the 1960s build and they were, to put it politely, past their prime. I'd been thinking about replacing them for a few years but it wasn't until we decided to do a proper renovation that I started seriously looking into what was actually available. A search for double glazed windows in Wollongong brought up RJV Industries Windows and after a few conversations, I was genuinely impressed. We ended up with uPVC double glazed windows from front to back and I wish we'd done it years earlier.

The Illawarra coast is a beautiful place to live but it comes with its own set of challenges for homeowners. Salt air accelerates corrosion on aluminium frames, coastal winds push noise through single-glazed windows, and the temperature swings between summer and winter can be more pronounced than people expect. Research shows that uPVC frames are significantly more resistant to corrosion and UV degradation than aluminium, making them a smart choice for coastal properties with a lifespan of 30 or more years with proper installation.

The Problem in Detail

Our home had aluminium single-glazed windows throughout. By the time we decided to renovate, about half of them were difficult to open, two had cracked seals, and all of them rattled when the southerly came through. Living near the Northern Illawarra line, train noise was a constant background hum that we'd stopped noticing consciously but definitely felt as a kind of low-level fatigue at the end of the day.

I'd looked at a few options during the renovation planning. Standard aluminium double glazing was one, uPVC frames another. The difference in thermal performance and longevity in a coastal environment made uPVC double glazed windows the clear choice on paper, but I wanted to speak to someone who could give me a straight answer about whether it was worth the additional investment for our specific situation.

How RJV Industries Windows Responded

I found RJV Industries Windows while researching uPVC window installers on the South Coast. They were responsive from the first enquiry, which already set them apart from a couple of other companies I'd contacted. They came out to inspect the house, took measurements, and had a detailed conversation about the renovation scope.

What stood out was that they understood the specific challenges of a beach-facing weatherboard home. They talked through the benefits of double glazed window units with acoustic laminated glass for the rooms facing the street and railway line, and standard double glazing for the rear of the house. That kind of nuanced recommendation gave me a lot of confidence. No overselling, just practical advice tailored to the property.

The whole quoting process was clear and detailed. Everything was broken down by room and window type so I knew exactly what we were getting and why. RJV Industries Windows also coordinated directly with our builder, which made the renovation process a lot smoother than it might have been.

The Solution and Outcome

RJV Industries Windows replaced every window in the cottage with uPVC double glazed windows, with acoustic laminated glass specified for the four front-facing windows. The frames were made to measure and the installation was completed over two days as part of the broader renovation schedule.

The noise reduction was the first thing I noticed. Standing in the front bedroom the evening after installation, the train noise that had been a constant companion was barely audible. My partner, who works from home, was almost emotional about it. The thermal improvement was the second thing: the cottage now holds its temperature far better in both directions, and we haven't needed the space heater in the front rooms since last winter.

The uPVC frames also look fantastic. The white finish suits the renovated weatherboard exterior and there's no sign of the salt air causing any surface issues twelve months in. Exactly what you'd hope for in a coastal property.

What Brendan Would Tell Others

If you're renovating a coastal home anywhere in the Wollongong or Illawarra area, don't just replace like for like. It's worth having a proper conversation about uPVC double glazing and what it can do specifically for your property type and location. The acoustic benefits alone were worth it for us.

Karen's Figtree Double Glazed Windows Story

Tue, 26 May 2026 19:57:30 GMT

I'd been putting it off for years. Every summer, the west-facing lounge in our Figtree home turned into a furnace by two in the afternoon, and every winter I'd find myself arguing with my husband about whether to turn the heating on. Our old aluminium single-glazed windows were doing absolutely nothing for us. A neighbour mentioned she'd had double glazed windows installed in Wollongong by RJV Industries Windows, and honestly, that one conversation changed everything. I started looking into uPVC double glazed windows properly for the first time and realised I'd been living with a very fixable problem for a long time.

We bought our 1980s brick veneer home knowing it needed work, but the windows kept falling to the bottom of the list. They weren't broken, just inefficient. Energy-efficient windows weren't something I'd given much thought to until our power bills started climbing year on year. Research into double glazing, thermal insulation, and noise reduction made it clear: studies suggest double glazed windows can reduce heat transfer by up to 50% compared to single glazed, which in an Illawarra summer is pretty significant.

The Problem in Detail

Our lounge room faces west, which means it cops the full force of the afternoon sun from about November through to March. We had heavy curtains, a ceiling fan, and a portable air conditioner that sounded like a small aircraft. None of it really worked. By 3pm the room was unusable, and by evening the heat had soaked into the walls. I'd looked at external awnings and window tinting but nothing felt like a proper long-term fix.

The windows themselves were original to the house. Single glazed, aluminium frames with that classic 1980s look that wasn't doing us any favours thermally or aesthetically. In winter they'd sweat with condensation and in summer they practically radiated heat inward. I knew replacing them was the right call but I wasn't sure where to start, what to ask for, or whether uPVC frames were worth the investment over standard aluminium replacements.

How RJV Industries Windows Responded

I gave RJV Industries Windows a ring after finding them through a Google search for double glazing installers near Wollongong. From the first call, it felt like talking to someone who genuinely knew their stuff and wasn't just trying to upsell me. They asked good questions about the orientation of the room, our main pain points, and our budget. No pressure, no hard sell.

The team came out to look at the property within a few days. They walked through the lounge, checked the existing frames, and talked us through the options in plain language. They explained the difference between various glass options and why a low-E coating made sense for a west-facing aspect. The recommendation was tailored to our actual situation rather than a one-size-fits-all solution. That kind of communication matters when you're making a significant investment in your home.

The Solution and Outcome

RJV Industries Windows installed uPVC double glazed windows across the entire west-facing side of the lounge and the adjoining dining area. The frames were custom-measured and the whole installation was completed in a single day with minimal disruption. The team was tidy, on time, and got the job done without any fuss.

The difference was noticeable almost immediately. That first afternoon, the room stayed genuinely comfortable well into the evening without the air conditioner running. The condensation we'd lived with every winter is completely gone. The house feels quieter too, which I hadn't anticipated. We live near the Princes Highway and I didn't realise how much traffic noise I'd been tuning out until it simply wasn't there anymore.

It's now been two summers since the installation and our power bills have dropped noticeably. The lounge is the most comfortable room in the house, which is something I honestly didn't think I'd be saying about a room that used to be unusable after midday.

What Karen Would Tell Others

Don't wait as long as I did. The upfront cost feels significant but once you're living with the result, you realise how much you were putting up with before. uPVC double glazed windows are a genuine upgrade to how your home feels day to day, not just a renovation checkbox.

If you're a homeowner in Wollongong thinking about double glazed windows in Wollongong , reach out to RJV Industries Windows and see what sets them apart from the rest.

How Retrofitted Double Glazing Reduces Noise Pollution

Fri, 11 Jul 2025 16:56:05 GMT

Noise pollution has become a growing problem for homeowners, particularly where busy roads, construction sites, and urban activity generate a constant background hum. For many, this continuous intrusion disrupts sleep, concentration and general wellbeing. While relocating isn’t always practical, solutions exist that can dramatically reduce external noise inside your home. One of the most effective methods is retrofitting double glazing into existing windows. In this blog, we’ll explore exactly how retrofitted double glazing works, why it effectively reduces noise pollution, and its many additional benefits.

Understanding the Growing Problem of Noise Pollution in Modern Homes

As towns and cities expand, noise pollution has become unavoidable for many households. New residential developments often sit alongside busy transport corridors, industrial sites, or commercial zones, leaving homeowners more exposed to external sounds than ever before.

Increased traffic from highways, major roads and public transport systems contributes to constant background noise.
Construction projects bring heavy machinery, equipment, and worker activity, often from early morning until late afternoon.
Air traffic routes can generate high levels of overhead noise, particularly for properties located near airports.
Suburban developments may also experience noise from local businesses, schools, sporting fields or entertainment venues.

Prolonged exposure to this noise isn’t just an inconvenience; it can have measurable impacts on physical and mental health, causing stress, disturbed sleep, anxiety, and even elevated blood pressure.

What is Retrofitted Double Glazing & How Does It Work?

Retrofitting double glazing allows homeowners to upgrade the performance of existing windows without replacing the entire window frame. This is particularly useful for older properties where full replacement may be expensive or structurally challenging.

A second pane of glass is installed inside the existing window frame, creating a sealed space between the original and new glass.
The space between the panes is typically filled with air or inert gas to reduce sound transmission and improve insulation.
High-quality seals are applied around the edges to ensure airtight performance, preventing air and noise from leaking into the home.

This method allows homeowners to benefit from modern double glazing technology while retaining the style and appearance of their existing windows.

How Double Glazed Windows Act as a Sound Barrier

The structure of double glazed windows makes them highly effective at reducing noise because they disrupt the transmission of sound waves before they enter your home. Instead of travelling straight through a single pane of glass, external noise is absorbed, reflected, and diffused as it passes through multiple layers.

The double layers of glass create a barrier that absorbs sound energy.
The sealed air or gas layer between the panes helps prevent sound vibrations from transferring directly through the window.
Thicker glass panes or specialised acoustic glass can further enhance soundproofing performance.

With double glazed windows installed, homeowners experience a noticeable drop in unwanted external noise, making homes feel quieter and more peaceful.

Living Near Busy Roads or Highways? Retrofitted Double Glazing Makes a Difference

For those close to major roadways, the benefits of retrofitted double glazing can be dramatic. Traffic noise from cars, trucks, buses and motorbikes often continues throughout the day and night, creating an ongoing disturbance that affects comfort and rest.

Retrofitted double glazing significantly reduces engine noise, tyre sounds, and braking screeches.
Overnight, heavy freight and delivery vehicles become far less intrusive indoors.
Sudden noises such as sirens, horns or loud music are dampened, creating a more consistent level of quiet inside the home.

For homeowners facing these daily disruptions, double glazing offers a highly effective way to regain control over their indoor environment.

The Role of Air Gaps & Sealed Units in Noise Reduction

The size of the air gap between the panes is one of the most important factors influencing how well double glazing reduces noise. Even small differences in gap size can affect how efficiently the system blocks out different sound frequencies.

Larger air gaps generally improve sound insulation, particularly for low-frequency noises.
Properly sealed units ensure airtight performance, preventing airborne sound from leaking through gaps or weak points in the window frame.
Additional acoustic treatments, such as laminated glass or specialised glazing combinations, can offer even greater protection against problematic noise sources.

Professional installation is essential to ensure all seals are correctly applied and the window performs as intended.

Retrofitted Double Glazing: A Cost-Effective Alternative to Full Window Replacement

One of the main advantages of retrofitted double glazing is its affordability compared to full window replacement. Retrofitting offers an ideal solution for homeowners who want to reduce noise but wish to avoid extensive renovations.

It allows you to upgrade your existing windows rather than removing and replacing entire frames.
The process is typically quicker, with minimal disruption to your household routine.
Retrofitting preserves the original appearance of heritage homes or architecturally designed properties where full replacement may not be suitable.

By choosing retrofitting, homeowners can achieve excellent noise reduction benefits without the higher costs often associated with full window replacement.

Added Benefits: Thermal Insulation & Energy Efficiency

Although many homeowners are drawn to double glazing for its noise reduction properties, the benefits of thermal insulation are equally valuable. Retrofitted double glazing helps stabilise indoor temperatures, which reduces heating and cooling costs throughout the year.

Heat loss through windows is minimised in winter, keeping indoor spaces warmer with less reliance on heating systems.
In summer, the same insulation prevents excess heat from entering, making it easier to keep homes cool.
Lower reliance on air conditioning and heating systems leads to noticeable energy savings and a more comfortable living environment.
Improved insulation also helps reduce condensation on windows, minimising moisture build-up and mould growth.

These additional benefits make retrofitted double glazing a smart, long-term investment for homeowners who want to enhance comfort and energy efficiency.

Why UPVC Windows & Doors Are A Durable & Low-Maintenance Choice

Fri, 23 May 2025 15:57:34 GMT

When building or renovating, your choice of windows and doors is not just about aesthetics; it’s about durability, comfort, and long-term value. More and more Australian homeowners are turning to UPVC windows and doors, and when combined with double glazing, these systems offer superior performance over traditional timber or aluminium options. Supplied by trusted window suppliers in Nowra, UPVC windows and doors are designed to handle tough climates while providing exceptional thermal performance, security, and style. Let’s explore eight compelling reasons why you should consider upgrading to UPVC windows and doors.

Built to Withstand Harsh Climatic Conditions

Australia’s varied climate—ranging from scorching summer heat to salty coastal breezes and heavy storms—requires materials that can last. UPVC windows and doors are engineered to resist these environmental stresses far better than wood or metal frames.

UPVC resists UV rays, preventing fading and brittleness under intense sunlight.
It does not corrode, making it perfect for coastal areas exposed to salt-laden air.
Unlike timber, it won’t swell or rot during wet seasons.
Double-glazed UPVC units add extra strength, helping to withstand storms and high winds.

This resilience means your windows and doors will look good and function well for decades, no matter where you live.

Low Maintenance, No Repainting or Resealing Needed

Many homeowners grow tired of sanding, painting, or resealing wooden or metal window frames year after year. UPVC eliminates this burden with an almost maintenance-free material.

Frames are coloured during manufacturing, so they never need repainting.
The surface resists peeling, cracking, and warping over time.
Cleaning requires a quick wipe with a damp cloth—no special treatments or coatings.
Double glazing reduces internal condensation, meaning less mould and dust around window frames.

This ease of care saves you countless hours and dollars on upkeep, letting you focus on enjoying your home instead of maintaining it.

Superior Energy Efficiency with Double Glazing

Energy efficiency is a top concern for many homeowners today, especially as electricity costs rise. UPVC windows and doors, particularly when double-glazed, deliver excellent thermal performance that reduces your home’s energy demands.

UPVC’s low thermal conductivity helps keep heat inside during winter and outside during summer.
Double-glazed units create an insulating air or gas barrier between glass panes.
Improved insulation reduces reliance on air conditioners and heaters, cutting energy bills.
Lower energy use translates into a smaller carbon footprint, contributing to sustainability goals.

With UPVC windows, you create a more comfortable, cost-effective, and environmentally friendly living space.

Enhanced Security Features for Peace of Mind

Feeling secure at home is priceless, and UPVC window and door systems are designed with security in mind. The combination of strong materials and advanced locking mechanisms makes them a smart choice for families.

Multi-point locking systems are standard on most UPVC windows and doors, making forced entry much harder.
Reinforced frames resist impact and tampering.
Double-glazed glass is tougher to break compared to single panes.
Secure seals and fittings ensure a tight closure, eliminating prying points.

Whether you live in a busy neighbourhood or a quiet street, UPVC systems help protect what matters most.

Noise Reduction for a Quieter Home Environment

If you live near a busy road, railway, or lively neighbourhood, you know how valuable a quiet home can be. UPVC windows and doors with double glazing provide effective noise insulation, creating a peaceful indoor retreat.

Dual glass panes block sound transmission from outside.
The air or gas layer between panes acts as a sound barrier.
UPVC frames feature multi-chambered profiles that absorb vibrations.
Tight window seals prevent draughts and noise leaks.

These features make a noticeable difference, letting you enjoy a calmer, more relaxing home environment.

Environmentally Friendly & Sustainable Choice

Today’s homeowners are increasingly aware of the environmental impact of their choices. UPVC windows and doors, particularly with double glazing, are a greener option supporting sustainable living.

UPVC is fully recyclable, reducing waste at the end of its long lifespan.
Its insulating properties lower household energy consumption.
Manufacturing processes are improving to reduce carbon emissions.
By using fewer materials for repairs and replacements, UPVC cuts long-term resource use.

Choosing UPVC windows and doors is a responsible step towards reducing your home’s environmental footprint.

Design Versatility to Suit Any Home Style

One of the biggest misconceptions about UPVC is that it only comes in white or looks too modern. In reality, UPVC windows and doors are available in a wide range of designs, making them suitable for contemporary and classic homes.

Choose from various colours, including timber-look finishes that mimic natural wood.
Select from styles such as sliding windows, casement windows, French doors, or bi-folds.
Customise glass options with frosted, tinted, or patterned glazing for added privacy or character.
Match frames to your home’s exterior, ensuring seamless architectural integration.

With this level of versatility, homeowners can enhance performance and style without compromise.

Long-Term Cost Savings on Repairs & Energy Use

While the upfront investment for UPVC windows and doors may be slightly higher than some alternatives, the long-term financial benefits are significant. Over time, they deliver considerable savings on energy, repairs, and maintenance.

Lower energy bills thanks to superior thermal insulation.
No ongoing painting, sealing, or corrosion repairs.
Fewer replacements are needed, as UPVC units have been without major issues for decades.
Enhanced property value due to modern, efficient, and attractive fittings.

By investing wisely now, you secure years of comfort, savings, and peace of mind.

How To Choose The Right Window Supplier For Your Home Renovation

Fri, 02 May 2025 16:39:58 GMT

Windows do far more than frame a view—they shape how your home looks, feels, and functions. From natural lighting and ventilation to insulation and security, the right windows can elevate your home's overall performance and aesthetic. That’s why choosing the right window supplier is one of the most important decisions in any renovation or build.

When handled well, your window installation will add long-term value and comfort. But if you choose the wrong supplier, you risk delays, poor-quality fittings, and windows that don’t perform as they should. In this blog, we’ll walk through what to look for when selecting a window supplier and why double-glazed windows are worth considering for any modern home.

Why Windows Matter in Home Renovation

Windows are often one of the most noticeable features of a home. They impact everything from street appeal and interior ambience to energy efficiency and sound insulation. In a renovation project, replacing or upgrading windows is a major opportunity to modernise your space while improving comfort and sustainability.

Whether you’re restoring an older property or designing a sleek new extension, working with a reliable window supplier ensures your project stays on track and that the products you install meet building standards and perform as expected.

What to Look for in a Window Supplier

Choosing a window supplier is about more than picking a product from a catalogue. You’re selecting a team to deliver and often install a critical part of your renovation. Here are key factors to consider:

Range & Customisation Options

A good supplier should offer a wide range of window styles to suit your home—whether it’s sliding, awning, casement, or fixed-panel designs. They should also be able to customise sizes and finishes to suit your project specifications.

Local Knowledge & Compliance

Different regions have varying climate demands and building codes. A local supplier will understand these requirements and help you select window systems that are appropriate for your environment and comply with all regulations.

For example, double-glazed windows are not only great for insulation but also meet stringent energy-efficiency standards, which are becoming increasingly important across many Australian states.

Quality of Materials & Craftsmanship

Check what materials the supplier uses—frames, seals, glass types—and whether their products are tested for durability, UV protection, weather resistance, and low maintenance.

High-quality double-glazed windows should include argon gas between panes, low-E coatings for energy efficiency, and seals that prevent condensation and heat loss.

Installation Services & Support

Some suppliers only sell the windows, leaving you to find your own installer. Ideally, choose a supplier that also offers professional installation or works closely with trusted tradespeople. Proper installation is key to long-term performance.

A poor installation—even with premium windows—can lead to draughts, leaks, and reduced insulation.

How to Assess the Reputation of a Window Supplier

Before signing any contracts, take time to assess the supplier’s credibility. Here's how:

Check customer reviews on independent platforms.
Request recent project examples or photos.
Ask for references from past clients.
Look for warranty coverage on products and workmanship.
Ensure they’re transparent with pricing, lead times, and delivery conditions.

Reputable suppliers will be happy to provide information and guide you through the selection process. Avoid any company that is vague about costs, unwilling to discuss timelines, or lacks a physical showroom or workshop.

Understanding the Benefits of Double-Glazed Windows

All of RJV Industries’ products are double-glazed, and for good reason. This type of window features two panes of glass separated by a sealed air or gas-filled gap, significantly improving energy and acoustic performance.

Here are just a few reasons why double-glazed windows are a superior choice for homeowners:

Energy Efficiency

Double glazing slows heat transfer, helping to keep your home cooler in summer and warmer in winter. This means reduced reliance on heating and cooling systems, resulting in lower energy bills.

Noise Reduction

Live near a busy road, school, or construction zone? Double-glazed windows reduce external noise, creating a more peaceful indoor environment—perfect for bedrooms, home offices, and living areas.

Enhanced Security

The extra pane of glass and sealed construction add strength to your windows, making them harder to break through compared to single-glazed alternatives.

Condensation Control

Double glazing reduces internal condensation by maintaining a consistent interior glass temperature. This helps to protect window frames, prevent mould, and reduce damp patches.

Property Value & Resale Appeal

Upgrading to double-glazed windows is a major drawcard for modern buyers. It shows that your home is energy-conscious and well-insulated—an important consideration in today’s real estate market.

Common Mistakes to Avoid When Choosing a Window Supplier

With so many choices, it’s easy to feel overwhelmed. Here are a few pitfalls to avoid:

Choosing based on price alone: Cheaper isn’t always better. Lower-cost products may compromise on quality or lack after-sales support.
Overlooking double glazing: Single-glazed windows may cost less upfront but offer poor thermal and noise performance in the long run.
Not factoring in timelines: Some suppliers have long lead times or delivery delays. Always confirm availability and production schedules early.
Ignoring installation quality: Even the best windows won’t perform well if poorly installed.

Matching Window Styles to Your Renovation

Selecting the right window type will depend on your design goals, natural light needs, ventilation, and space availability.

Here are some common styles to consider:

Sliding Windows: Great for maximising light and airflow in modern spaces.
Awning Windows: Perfect for controlled ventilation, even during rain.
Casement Windows: Offer full opening and are often used in traditional designs.
Fixed-Panel Windows: Ideal for floor-to-ceiling glass areas and views.
Double-Hung Windows: A timeless style, often used in heritage renovations.

All of these can be double-glazed and tailored to match your frames, finishes, and layout preferences.

Quality Windows Start with the Right Supplier

Windows play a major role in the success of any home renovation. They shape the look and feel of your space, influence energy efficiency, and contribute to daily comfort. But not all windows—or suppliers—are created equal.

Choosing the right provider means gaining access to quality products, professional advice, and long-lasting value. For modern builds or renovations, double-glazed windows offer the best in insulation, durability, and performance.

At RJV Industries , we supply only high-performance double-glazed windows that are tailored to your project needs. Whether you’re renovating a single room or redesigning your entire home, we’re here to provide reliable products and personalised support.

The Latest Trends in Modern Window Designs

sales@digitaldoor.ai (David Holihan) — Tue, 21 Jan 2025 19:17:38 GMT

Minimalist Window Frames

Modern design embraces clean lines and simplicity, and this trend is evident in window frames. Homeowners are opting for slim, barely-there frames that maximise glass area, allowing for uninterrupted views and increased natural light.

Popular Choices:

Aluminium frames are strong, durable, and perfect for achieving a sleek, contemporary look. They are also lightweight, resistant to rust, and offer a minimalistic appearance without compromising on strength.
Black and dark-toned frames are a bold contrast against neutral interiors, adding a striking architectural element. These dark frames highlight the view and create a more dramatic effect, making them popular for modern, industrial, and minimalist designs.

Minimalist frames contribute to a streamlined and sophisticated aesthetic while keeping homes well-lit and airy.

Energy-Efficient Double-Glazed Windows

With growing awareness of sustainability and energy efficiency, double-glazed windows have become a staple in modern homes. These windows feature two panes of glass separated by an insulating layer, helping to:

Reduce heat transfer, keeping homes warmer in winter and cooler in summer by effectively trapping heat inside during colder months and blocking it out during the warmer months.
Improved insulation and maintenance of a consistent indoor temperature can lower energy costs and reduce reliance on heating and cooling systems, which in turn helps to cut down on energy consumption.
Improve sound insulation, minimising outside noise for a quieter living environment by absorbing and dampening sound waves between the two layers of glass.

For homeowners in Nowra and beyond, investing in double-glazed windows enhances comfort and aligns with eco-friendly home improvement trends.

Floor-to-Ceiling Glass Windows

Expansive glass panels are a game-changer for modern homes, creating seamless indoor-outdoor connections and maximising natural light. Floor-to-ceiling windows work particularly well in homes with open-plan layouts, offering:

Unobstructed views of outdoor landscapes.
A feeling of spaciousness and openness.
Enhanced ventilation when combined with sliding or bi-fold options.

If privacy is a concern, tinted or frosted double-glazed windows can provide aesthetics and discretion without sacrificing light.

Windows play a crucial role in home design, balancing aesthetics, functionality, and energy efficiency. As modern architecture evolves, so do window styles, materials, and features. If you’re planning a renovation or new construction, keeping up with the latest window trends can help you create a stylish and practical living space. Here’s a look at the latest innovations in modern window designs and how they enhance both form and function.

How Double Glazed Windows Enhance Home Comfort

Mon, 18 Nov 2024 17:53:01 GMT

When it comes to making your home more comfortable and energy-efficient, double glazed windows are a game-changer. These windows aren’t just a luxury—they’re an investment in creating a better living environment. Here’s how double glazed windows can transform your home for the better.

Temperature Control For Year-Round Comfort

One of the standout features of double glazed windows is their ability to maintain a consistent indoor temperature, regardless of the weather outside. Double glazing involves two glass panes separated by a layer of insulating gas, which acts as a barrier to heat transfer. This design reduces heat loss in winter and prevents heat gain in summer, allowing you to enjoy a stable and comfortable indoor temperature all year long.

Benefit : With double glazed windows, your home will feel warmer in winter and cooler in summer, reducing the need for constant heating and cooling. This helps maintain a cozy environment and can lower energy bills, as your HVAC system won’t have to work as hard to regulate indoor temperatures.

Enhanced Noise Reduction For A Peaceful Living Space

If you live in a busy area or near a noisy street, the soundproofing benefits of double glazed windows can make a huge difference. The two glass panes and the insulating gas layer work together to create an effective sound barrier, blocking out unwanted noise from outside. This feature is particularly valuable for bedrooms, living rooms, or home offices where a quiet environment is essential.

Benefit : Double glazed windows reduce external noise, creating a calm and peaceful space inside your home. This feature enhances relaxation, focus, and overall comfort, even in noisy neighbourhoods.

Improved Indoor Air Quality By Reducing Draughts And Condensation

Double glazed windows are highly effective at reducing draughts, which improves temperature control and minimises the entry of airborne pollutants, allergens, and dust. Additionally, these windows help reduce condensation, a common issue with single-paned windows that can lead to mould growth and decrease indoor air quality.

Benefit : With double glazed windows, you’ll experience fewer draughts, leading to better air quality and a healthier home environment. Reduced condensation also helps prevent moisture-related issues, keeping your home’s interior clean and fresh.

Increased Home Security for Peace of Mind

Double glazed windows add a layer of security to your home. The two panes of glass make it harder for potential intruders to break through, providing an extra level of protection for your family and belongings. Additionally, double glazed windows from RJV Industries are designed with durable, quality materials that further enhance their strength and resistance to impact.

Benefit : With double glazed windows, you can feel more secure at home, knowing that your windows provide an extra barrier against break-ins. This added security is especially valuable for ground-level windows and areas that need extra protection.

Eco-Friendly Choice with Energy Efficiency Benefits

If you’re looking to make environmentally friendly choices for your home, double glazed windows are a great option. Their insulation properties lead to less energy consumption, reducing your carbon footprint. By keeping your home naturally warmer in winter and cooler in summer, double glazed windows help you consume less energy, which is better for the environment.

Benefit : Choosing double glazed windows is beneficial for your home’s comfort and contributes to a more sustainable lifestyle by lowering energy usage and greenhouse gas emissions.

Transform Your Home with Energy-Efficient Double Glazed Windows

At RJV Industries, we offer high-quality double glazed windows in Nowra that help enhance home comfort and energy efficiency.

Single Vs Double Glazed Windows: Which is Best for Your Home?

Tue, 15 Oct 2024 19:30:24 GMT

Thermal Insulation

Single-glazed windows have one layer of glass, which doesn’t do much to stop heat transfer. As a result, they’re not the most energy-efficient option, allowing warmth to escape during winter and heat to seep in during summer. This can lead to higher energy bills as your heating and cooling systems work overtime.

Double-glazed windows have two layers of glass with a gap in between, often filled with gas, making double-glazing a game-changer. It creates an insulating barrier that significantly reduces heat transfer, keeping your home at a more consistent temperature. This means less reliance on air conditioning and heating systems, helping you save on energy costs.

Are you tired of high energy bills or dealing with noisy neighbours? If you’re considering upgrading your windows, you’ve likely come across terms like single and double glazing. But what’s the difference and which one’s right for your home? Here’s a side-by-side comparison to help you make an informed decision.

Noise Reduction

If you live near a busy road or in a noisy neighbourhood, single-glazed windows won’t block much sound. Their single layer of glass offers minimal soundproofing, leaving you more exposed to external noise. Over time, this can negatively impact your comfort and peace of mind at home.

On the other hand, double-glazed windows are much better at blocking out noise. The space between the panes, often filled with inert gas, dampens sound waves, creating a more peaceful home environment. This can be especially beneficial if you live in an urban area or near a high-traffic zone.

The insulating properties of double-glazed windows mean your heating and cooling systems don’t have to work as hard to maintain a comfortable indoor temperature. This results in a noticeable reduction in your monthly energy bills. Since these windows are designed to last for decades, the ongoing energy savings will continue to accumulate, making them a cost-effective choice for the long term.

Durability & Maintenance

While single-glazed windows can be cheaper upfront, they tend to lack durability. They’re more prone to breakage and wear and tear, requiring frequent maintenance and possible replacement over time.

Double-glazed windows are much more durable. Their two layers of glass offer greater strength and are less likely to crack or shatter. Additionally, modern double-glazed windows come with uPVC frames that resist UV damage, corrosion and even fire. This makes them an ideal choice for homes in coastal areas, where weather conditions can be harsh.

Cost

Single glazing may seem like a budget-friendly option, but the long-term costs can quickly add up. Higher energy bills and more frequent repairs or replacements could make single glazing a more expensive choice over time.

While double-glazed windows require a larger initial investment, the long-term benefits far outweigh the upfront cost. The energy savings, reduced noise and greater durability make them a sound investment for homeowners looking for a lasting solution.

Environmental Impact

Due to their poor insulation properties, single-glazed windows contribute to higher energy consumption. This increases your household’s carbon footprint and adds to the environmental burden.

If you’re looking to make your home more eco-friendly, double-glazed windows are the way to go. Their energy-efficient design reduces your home’s reliance on heating and cooling systems, helping to lower your overall energy consumption and environmental impact.

Why Choose Double Glazed Over Single Glazed?

In short, double-glazed windows provide superior benefits in terms of energy efficiency, noise reduction, durability and environmental sustainability. While the initial cost might be higher, the long-term savings on energy bills and the reduced need for maintenance make double glazed windows a smart, cost-effective upgrade for any home.

Reduce Your Energy Bills with Double-Glazed Windows

Double-Glazed Windows: An Investment Worth Making

Thu, 05 Sep 2024 18:38:12 GMT

Understanding the Basics

Double-glazed windows consist of two panes of glass separated by a gap filled with an insulating gas, typically argon or krypton. This gas is denser than air, enhancing its ability to reduce heat transfer. A spacer bar, typically made from durable materials like aluminium or composites, maintains the space between the glass panes, ensuring a uniform gap for consistent insulation performance. This design improves the thermal characteristics and ensures the structural integrity of the window.

To maintain the insulating properties over time, the edges of the glass panes are tightly sealed with materials that prevent moisture from penetrating. A desiccant-lined spacer bar absorbs any residual moisture within the sealed gap, preventing condensation from forming between the panes. This meticulous construction ensures long-term efficiency, as the window remains tightly sealed and stable. It keeps the insulating gas in place and safeguards the window's thermal performance throughout its lifespan.

Financial Benefits of Double-glazed Windows

While the initial cost of installing double-glazed windows may be higher than single-glazed alternatives, the long-term financial benefits make this investment worth it. Here’s how double glazing can provide a strong return on investment (ROI):

Lower Energy Bills

Increased Property Value

These windows are often viewed as a desirable feature. Installing them can make your home more attractive to potential buyers. This can increase the overall appraisal value of your home, helping you get a better return on your investment if you decide to sell.

Additional Benefits of Double Glazing

Beyond the financial advantages, double-glazed windows offer several benefits that significantly improve your home's comfort and quality of life.

When it comes to home improvements, deciding where to invest can be challenging. Homeowners often look for upgrades that enhance comfort and property value while providing long-term benefits. For those considering renovations or upgrades, double-glazed windows deliver excellent value. In this blog, we’ll explore the benefits of installing these windows.

Enhanced Comfort

Temperature Stability : With these windows, you can enjoy a more stable indoor environment, no matter the weather outside. This makes your living spaces more comfortable and enjoyable year-round.
Noise Reduction : These windows also provide excellent sound insulation. If you live near a busy road or in a noisy neighbourhood, these windows can significantly reduce outside noise, creating a quieter, more peaceful living environment.

Improved Home Security

Tougher to Break : The two layers of glass, combined with the space between them, make double-glazed windows much more difficult to break than ones with single-pane. This can deter potential intruders and give homeowners peace of mind.
Added Safety : In the event of an accident or natural disaster, double-glazed windows are less likely to shatter, reducing the risk of injury from broken glass.

Guide To Selecting Durable Double Glazed Windows

Thu, 01 Aug 2024 18:29:57 GMT

Understanding Double Glazing Technology

Double glazing involves two panes of glass separated by a spacer filled with air or inert gas, offering superior insulation compared to single-pane windows.

Insulation Benefits

The space between the glass panes acts as a thermal barrier, reducing heat transfer and helping to maintain a consistent indoor temperature, which improves energy efficiency.

Noise Reduction

Double glazing significantly decreases outside noise, creating a quieter and more peaceful living environment.

Enhanced Security

The dual layers of glass make it more difficult for intruders to break through, providing an extra layer of protection for your home.

What Makes Double Glazed Windows Durable?

The durability of double glazed windows largely hinges on their design and materials. Unlike single glazed windows, double glazed windows feature two layers of glass with a space in between, usually filled with air or an inert gas like argon. This design significantly enhances the window’s insulation properties, reducing energy consumption and improving noise reduction.

The materials used in the construction of the window frames also contribute to their durability. Frames made from high-quality uPVC , aluminium, or timber are designed to withstand various environmental stresses, from intense sunlight to heavy rain. Additionally, these materials resist warping and corrosion, which are common issues that can reduce the lifespan of windows.

What To Look For When Selecting Double Glazed Windows

When choosing double glazed windows, there are several factors to consider to ensure you get the most durable option available:

Glass Thickness and Type : The thickness of the glass plays a crucial role in durability. Look for windows with at least 6mm glass thickness. Additionally, toughened or laminated glass should be considered for extra strength and safety.
Spacer Technology : The spacer in double glazed windows keeps the glass layers apart. High-quality spacers made from durable materials such as stainless steel or those with thermal barriers can enhance the window’s longevity.
Frame Material : Choose frames made from robust materials such as uPVC, which is known for its energy efficiency and resistance to the elements, or aluminium for a sleek, modern look and added strength.
Seal Quality : Inspect the seals around the window edges. Poor-quality seals can deteriorate quickly, allowing moisture ingress and damaging the window’s structural integrity.
Energy Rating : Opt for windows with a high energy rating. These windows contribute to better insulation and are typically made from higher-quality materials designed to last longer.

How Can You Ensure Your Windows Will Last?

Here are the things to consider:

Regular Maintenance : Clean windows with mild detergent and check seals for wear to prevent minor issues from becoming major repairs.
Consider Local Climate : Choose windows rated for your climate to prevent problems like condensation and frame warping.
Choose a Reputable Supplier : Partner with a trusted supplier for high-quality, tailored windows. They offer expert advice, professional installation and excellent after-sales service, ensuring a long-lasting investment.

How Modern Windows Can Transform Your Home

Thu, 06 Jun 2024 17:46:17 GMT

Have you ever wondered how a simple change like upgrading your windows could transform your home? Modern window technologies have revolutionised the way we live, offering more than just a view of the outside world. From enhancing your home’s energy efficiency to boosting its aesthetic appeal, the benefits are truly remarkable. Let’s explore five ways modern windows can make a significant difference in your living space.

Improved Insulation For Year-Round Comfort

One of the standout advantages of modern windows is their exceptional insulation capabilities. Unlike older, single-pane windows, modern options like double-glazed windows provide superior thermal insulation. This means your home stays cooler in the summer and warmer in the winter, significantly reducing your reliance on heating and cooling systems. As a result, you enjoy a more comfortable living environment and save on energy bills.

Double-glazed windows feature two layers of glass with a gap in between, acting as a barrier to heat transfer. This design helps maintain a consistent indoor temperature, reducing the workload on your AC system and contributing to a more energy-efficient home. With improved insulation, you can say goodbye to those chilly drafts and sweltering hot spots, enjoying a perfectly balanced climate all year round.

Enhanced Noise Reduction For A Peaceful Home

Living in a bustling neighbourhood or near a busy street can often mean dealing with unwanted noise. Modern windows, particularly double-glazed ones, are designed to tackle this issue head-on. The dual layers of glass, combined with the insulating gap, effectively reduce noise pollution, creating a serene and quiet indoor environment.

Whether it’s the sound of traffic, noisy neighbours or other urban clamour, modern windows act as a barrier, allowing you to enjoy peace and tranquillity in your home. This noise reduction feature is especially beneficial for those working from home, parents with young children or anyone seeking a restful and undisturbed living space.

Increased Security For Peace Of Mind

Home security is a top priority for every homeowner and modern windows play a crucial role in enhancing it. Traditional windows with single panes are relatively easy to break, posing a security risk. In contrast, modern windows offer increased strength and durability, particularly those with double glazing.

The construction of double-glazed windows makes them much harder to break, deterring potential intruders and providing an added layer of security. Some modern windows also come with advanced locking mechanisms and reinforced frames, further enhancing the safety of your home. By upgrading to modern windows, you can have peace of mind knowing that your home is better protected against break-ins.

Enhanced Aesthetic Appeal And Property Value

Modern windows are not just functional; they also add a touch of elegance and style to your home. With various designs, finishes and customisation options available, you can choose windows that complement your home’s architectural style and personal taste. Whether you prefer sleek, contemporary designs or classic, timeless looks, there’s a modern window option for every preference.

Upgrading your windows can also significantly boost your property’s curb appeal and market value. Prospective buyers often look for homes with energy-efficient and aesthetically pleasing features. By investing in modern windows, you’re enhancing your living experience and making a smart financial decision that could yield a higher return on investment when it comes time to sell.

Upgrade To Modern Windows For Ultimate Comfort And Security

Modern windows offer numerous benefits, from improved insulation and noise reduction to enhanced security and aesthetic appeal. At RJV Industries , we provide high-quality modern windows with exceptional insulation, noise reduction and enhanced security. Our double-glazed windows are designed to improve your living environment while contributing to a sustainable future.

How To Maintain Your Windows And Doors For Longevity

Wed, 27 Mar 2024 16:17:48 GMT

Windows and doors are the essential barriers that separate the cosy interior of your home from the external environment. Maintaining these key architectural features is crucial for their longevity and effectiveness. In this blog, we’ll share practical tips to help you preserve the condition of your doors and windows. By following these steps, you can ensure these elements remain durable and visually appealing.

SUSTAINING WINDOWS AND DOORS THROUGH REGULAR CLEANING

Regular maintenance is key to extending the life of your doors and windows. Here’s how to keep them in top condition:

Gentle Washing : Use a soft cloth or sponge and a mild detergent to gently wash the glass and frames. These will remove grime without scratching or damaging the surfaces.
Rinse Thoroughly : Rinse the frames and glass with clean water to remove any soap residue, which can attract more dirt if left behind.
Dry Completely : Use a dry, lint-free cloth to remove moisture. It prevents streaks on the glass and water damage to the frames.

While cleaning, take the opportunity to inspect your doors and windows. If you notice any damage, address it immediately. Incorporating these steps into your regular maintenance schedule will help ensure these critical features of your home remain functional.

IDENTIFYING AND ADDRESSING WEAR AND TEAR

Over time, windows and doors are subjected to the wear and tear of daily use. It can lead to common issues such as drafts, leaks, difficulty opening or closing and compromised security. Regular inspection is key to identifying these problems early. Look for signs of wear, such as deteriorating weatherstripping, rusting metal components or warping and rotting frames. These indicators can affect the functionality and energy efficiency of your doors and windows.

Once you’ve identified potential issues, taking prompt action can prevent minor problems from escalating into costly repairs. Replacing worn weatherstripping or sealing cracks and gaps can dramatically improve insulation and reduce energy bills. A bit of lubrication can often restore smooth operation for hardware issues like stiff locks or squeaky hinges. For more serious problems, such as rotting wood or cracked glass, consulting with a professional for repair or replacement may be required. By staying vigilant and proactively addressing these signs of wear and tear, you can ensure your windows and doors serve you well for years.

THE IMPORTANCE OF AVOIDING HARSH CHEMICALS

It might be tempting to use strong cleaning agents to bring back the sparkle of your windows and doors. However, it’s important to keep in mind that these can inadvertently damage them. For instance, harsh chemicals can strip away finishes, degrade seals and even corrode metal components. Over time, this can lead to a loss of aesthetic appeal and functionality, necessitating premature repairs or replacements.

Instead of reaching for the strongest cleaner in the cupboard, opt for mild, non-abrasive soaps mixed with water for a gentle yet effective cleaning solution. For tougher stains, consider using natural alternatives like vinegar or baking soda, which are less likely to cause damage. These options are not only safer for your windows and doors, but they’re also better for the environment and your health.

INVEST IN THE LONG-LASTING PERFORMANCE OF YOUR WINDOWS AND DOORS

In conclusion, maintaining your doors and windows doesn’t have to be a challenging task. The key is consistent care, timely identification of wear and tear and the avoidance of harsh chemicals.

How Double-Glazed Windows And Doors Can Improve Home Security

Tue, 01 Aug 2023 18:00:24 GMT

Ensuring home security goes beyond relying on locking mechanisms and burglar alarms. When assessing potential vulnerabilities, windows and doors are often important aspects to consider. This is where double-glazed windows and doors prove their worth. But do they offer greater security than their counterparts? Let’s dive into the details to find out.

THE STRUCTURE OF DOUBLE-GLAZING

Two Layers to Break Through : The double-layer glass construction makes it difficult for intruders to break through.
Gap Filled with Gas: The gap filled with inert gas or air provides an additional level of resistance to impact, making it even harder for the glass to break.
Sealed Units: Double-glazed units are tightly sealed. Even if the external pane is compromised, the sealed unit’s integrity makes it difficult to dislodge the entire assembly.

IMPROVED SECURITY MEASURES WITH DOUBLE GLAZING

When discussing the security aspects of double-glazing, it’s not just about the glass. The design and construction of these windows and doors often integrate other security enhancements that provide an extra level of protection.

LOCKING SYSTEMS

Double-glazed windows and doors come equipped with a superior locking mechanism compared to traditional single-glazed units. These multi-point locking systems provide more than just one secure point. They secure the window or door at multiple points along its length when locked, increasing its resistance to forced entry.

WINDOW BEADING

Window beading in double-glazed units offers an additional layer of protection. This is the moulding or trim that keeps the glass panes in place within the frame. The beading is often installed from the inside rather than the outside. This means that even if an intruder manages to break the glass, they can’t easily dislodge the rest of the window to create an opening.

LAMINATED OR TOUGHENED GLASS OPTIONS

For those seeking additional peace of mind, opting for laminated or toughened glass in double-glazed units can significantly boost their resistance to breakage. Laminated glass is created by placing a plastic interlayer between two glass panes, making it an exceptionally strong material. Toughened or tempered glass, on the other hand, is treated to make it up to five times stronger than regular glass.

REINFORCED FRAMES

Lastly, the frames of double-glazed windows and doors are generally reinforced to provide additional structural strength. These frames are designed to resist warping, bending and physical attacks, thus making it harder for potential intruders to gain entry.

By combining all these features, double-glazed windows and doors offer an increased level of security, deterring potential intruders and giving homeowners peace of mind.

Double-glazed windows can transform your living space into a haven of comfort, energy efficiency and security. They can help you cut down on energy bills, reduce intrusive noise and avoid the discomfort of extreme temperatures. Let’s discover the advantages that await you when you choose double-glazed windows.

THERMAL INSULATION

Two layers of glass with an insulating gap in between create a barrier against heat transfer.
During summer, double-glazed windows prevent external heat from entering the home, keeping the interior cool and reducing reliance on air conditioning.
In winter, they retain warmth indoors, reducing the need for excessive heating and resulting in energy savings.

ACOUSTIC INSULATION

Whether you reside near a busy street, construction site or airport, double-glazed windows can create a quieter and more serene living space.
The combination of two glass layers with an air or gas-filled gap reduces sound transmission.
Noise vibrations are dampened which makes it difficult for them to enter the home.

INCREASED SECURITY

The dual glass layers make it more difficult for intruders to break through compared to single-pane windows.
The space between the glass layers is filled with an insulating gas, such as argon, which adds to the structural integrity of the window.
Double-glazed windows may come equipped with advanced locking systems, further fortifying the security of your home.

REDUCED CONDENSATION

The consistent temperature maintained on the inner glass layer reduces the formation of moisture.
This is especially beneficial in areas like bathrooms and kitchens, where condensation tends to occur more frequently.
By reducing condensation, double-glazed windows also prevent mould growth.

UV PROTECTION

Double-glazed windows can block some of the sun’s UV rays from entering your home.
This helps prevent the fading, discolouration and deterioration of your valuable possessions, preserving their beauty and extending their lifespan.
Additionally, UV protection contributes to safeguarding your skin from the harmful effects of prolonged sun exposure.

LESS MAINTENANCE

The combination of high-quality materials, such as sturdy frames and durable glass, ensures longevity and resistance to wear and tear.
With proper care, these windows can maintain their functionality and aesthetics for many years.
Keeping the windows clean and inspecting them periodically for any signs of damage or wear is usually sufficient to maintain their performance.
