If you’re renovating a Toorak villa, upgrading your Fitzroy terrace, or building a new home in Werribee, you’ve probably found yourself staring at window brochures wondering whether double glazed windows Melbourne homeowners rave about are enough—or if you should stretch the budget for triple glazing. It’s one of those decisions that keeps you awake at night, especially when you’re investing tens of thousands of dollars into something you’ll live with for decades.
Here’s the thing: Melbourne’s weather doesn’t make this decision any easier. One day you’re cranking the heater as a cold front sweeps up from the Southern Ocean, the next you’re desperately opening windows during a 38-degree scorcher. Our city’s notorious “four seasons in one day” reputation means your windows need to work harder than almost anywhere else in Australia.
I’ve spoken with hundreds of Melbourne homeowners who’ve stood exactly where you are now. Some regret not spending more on better insulation. Others wish they’d saved money and stuck with double glazing. The truth? There’s no one-size-fits-all answer, but there are clear guidelines that can help you make the right choice for your specific situation, suburb, and budget.
Dena Windows and Doors has helped thousands of Melbourne families make this exact decision since we started serving Victoria. We’ve installed everything from heritage-appropriate double glazing in Carlton terraces to cutting-edge triple glazed systems in modern Balwyn homes. What we’ve learned is that the “best” choice depends on factors most homeowners don’t initially consider—and that’s exactly what this guide will unpack.
Over the next few minutes, you’ll discover the real differences between double and triple glazing (beyond the marketing hype), how Melbourne’s unique climate affects your decision, what you can expect to pay across different suburbs, and which option actually delivers better value for your specific circumstances. Whether you’re in Brighton battling salt air corrosion or in Dandenong watching your energy bills climb, we’ll help you make an informed decision that you’ll feel confident about for years to come.
Let’s dive into what really matters when choosing between double and triple glazed windows for your Melbourne home.
Double Glazed Windows in Melbourne: What You Need to Know
Double glazed windows have become the standard for quality home construction and renovation across Melbourne and Victoria. But what exactly are they, and why have they become so popular?
At their core, double glazed windows consist of two panes of glass separated by a sealed air gap—typically between 12mm and 16mm wide. This space is often filled with argon gas, which provides better insulation than regular air. The entire unit is sealed to prevent moisture infiltration and maintain the insulating properties.
In our experience working across Melbourne suburbs, double glazing delivers substantial benefits:
The thermal performance alone is impressive. Double glazed windows can reduce heat loss by up to 30% compared to single-pane windows—a significant improvement that Melbourne homeowners notice immediately on their energy bills. During those bitter July mornings in Eltham or scorching January afternoons in Frankston, that insulation barrier works overtime.
Noise reduction is another major advantage. If you live near a busy road in Richmond or under a flight path in Tullamarine, double glazing can reduce outside noise by 30-50 decibels. That’s the difference between hearing every truck rumble past and enjoying peaceful conversations in your living room.
Condensation control matters more than most people realize. Melbourne’s humidity—especially in bayside suburbs like Sandringham and Mordialloc—can create serious condensation problems with single-pane windows. Double glazing dramatically reduces this issue by keeping the inner pane closer to room temperature.
We’ve installed double glazed windows in over 8,000 Melbourne properties, and the feedback consistently highlights improved comfort, lower energy costs, and better sleep quality. Many Melbourne customers often choose double glazing because it offers excellent value—delivering 80% of the benefits of triple glazing at roughly 60% of the cost.
The lifespan is another selling point. Quality double glazed windows from Dena Windows and Doors typically last 20-25 years with minimal maintenance. The sealed units maintain their insulating properties for decades, making them a genuine long-term investment rather than just a cosmetic upgrade.
For most Melbourne homes—particularly in suburbs like Footscray, Preston, Coburg, and Reservoir—double glazing provides more than adequate performance. The climate simply doesn’t demand the extreme insulation that homeowners in Canberra or Ballarat might need.
Why Triple Glazed Windows Are Gaining Popularity Across Victoria
Triple glazed windows represent the premium tier of window insulation technology. They feature three panes of glass with two sealed air gaps, typically filled with argon or krypton gas for maximum thermal performance.
While triple glazing has been standard in Scandinavian countries and parts of Europe for decades, it’s only recently gained traction in Australia. So why are more Melbourne homeowners considering this premium option?
The thermal performance is genuinely impressive. Triple glazed windows can reduce heat transfer by up to 50% compared to double glazing—and up to 70% compared to single-pane windows. For Melbourne’s coldest suburbs like Belgrave, Warburton, and the Dandenong Ranges, this extra insulation can transform winter comfort.
The noise reduction capabilities are exceptional. Triple glazing can block up to 60 decibels of external noise—making it ideal for homes on busy arterials like Punt Road, Hoddle Street, or near Melbourne Airport. If you’ve ever tried to sleep through peak-hour traffic in South Yarra or Kew, you’ll appreciate what that extra pane can do.
UV protection is another significant advantage. Melbourne’s harsh UV levels (often reaching extreme levels in summer) can fade furniture, artwork, and flooring. Triple glazed windows with low-E coatings can block up to 99% of UV rays while still allowing natural light through—protecting your interior investments.
Heritage home owners in suburbs like Hawthorn, Armadale, and Malvern are increasingly choosing triple glazing for a specific reason: it allows them to maintain single-pane aesthetics while achieving modern performance standards. Dena Windows and Doors recommends custom-designed triple glazing for heritage properties where council regulations restrict external appearance changes.
The condensation elimination is virtually complete. Even in Melbourne’s most humid conditions—like those muggy summer nights in Williamstown or morning fog in Yarra Glen—triple glazing keeps interior pane temperatures high enough to prevent any moisture buildup.
Security is an often-overlooked benefit. Three panes of glass with modern locking systems create a genuinely robust barrier. For ground-floor windows in any Melbourne suburb, this added security provides peace of mind that’s hard to quantify but easy to appreciate.
The investment perspective matters too. While triple glazing costs significantly more upfront, property valuers increasingly recognize premium windows as a genuine value-add. In high-end markets like Toorak, Brighton, and Canterbury, triple glazing is becoming an expected feature rather than a luxury upgrade.
Climate change considerations are driving some forward-thinking homeowners toward triple glazing. As Melbourne’s weather patterns become more extreme—hotter summers, colder winters, more variable conditions—the superior insulation of triple glazing provides future-proofing that double glazing can’t quite match.
Double vs Triple Glazing: Which Suits Your Melbourne Suburb?
Location matters more than most homeowners realize when choosing between double and triple glazing. Melbourne’s diverse suburbs experience surprisingly different microclimates, and your specific area should influence your decision.
Inner Melbourne Suburbs (Fitzroy, Carlton, Collingwood, Richmond)
These heritage-rich suburbs present unique challenges. Period homes with original features need sympathetic upgrades that respect architectural character while delivering modern performance.
For most inner-city terraces and Victorian-era homes, double glazing strikes the perfect balance. It provides substantial improvement over single panes without the weight concerns that triple glazing can create in older frames. Many Melbourne homeowners ask us whether heritage overlays allow window upgrades—the answer is usually yes, provided you maintain the original appearance from street view.
The noise reduction from double glazing is particularly valuable here, given the proximity to busy streets, trams, and nightlife. We’ve installed over 2,000 double glazed windows across these inner suburbs, and residents consistently report dramatic improvements in livability.
Eastern Suburbs (Toorak, Malvern, Camberwell, Kew)
These affluent areas feature larger homes with higher expectations for comfort and performance. Triple glazing is increasingly becoming the standard for new builds and major renovations.
Our Melbourne customers often choose triple glazing in these suburbs because the investment aligns with overall property values. When you’re spending 2−3 million on a home, the additional 2-3 million on a home, the additional 15,000-20,000 for triple glazing represents excellent value for the comfort and efficiency gains.
The superior noise reduction matters in these areas too—not from traffic, but from maintaining privacy and tranquility in densely populated neighborhoods where homes sit close together.
Bayside Suburbs (Brighton, Sandringham, Black Rock, Beaumaris)
Salt air corrosion is the hidden enemy for windows in coastal suburbs. Both double and triple glazing need specialized treatments, but the decision between them often comes down to exposure levels.
Dena Windows and Doors recommends marine-grade frames with either double or triple glazing depending on your proximity to the beach. Homes within 500 meters of Port Phillip Bay benefit from the extra protection that triple glazing’s additional seals provide against salt penetration.
The thermal performance matters less here—Melbourne’s bayside suburbs enjoy moderated temperatures thanks to the bay effect. However, the UV protection from triple glazing’s low-E coatings is particularly valuable given the intense sun exposure these properties receive.
Outer Suburbs (Dandenong, Werribee, Melton, Pakenham)
Budget considerations become more pressing in these growth corridors, where families are often balancing multiple renovation priorities.
Double glazing delivers outstanding value in these suburbs. The cost savings compared to triple glazing can be redirected toward insulation, heating systems, or other energy-efficiency measures that might deliver better overall value.
That said, we’ve found that families planning to stay in these homes long-term increasingly opt for triple glazing in living areas and main bedrooms, using double glazing in secondary spaces—a hybrid approach that optimizes both performance and budget.
Hills and Ranges (Belgrave, Emerald, Warburton, Olinda)
These elevated areas experience Melbourne’s coldest temperatures and most extreme weather conditions. If there’s anywhere in greater Melbourne where triple glazing makes undeniable sense, it’s here.
The temperature differential between the Dandenong Ranges and Melbourne CBD can reach 5-8 degrees on winter mornings. That extra insulation from triple glazing translates to genuine comfort improvements and heating cost savings that justify the investment within 7-10 years.
We’ve installed over 500 triple glazed window systems across the ranges, and the feedback is unanimous—the difference is immediately noticeable and consistently appreciated throughout Melbourne’s long heating season.
Energy Efficiency in Melbourne’s Climate: A Comparative Analysis
Let’s talk numbers, because ultimately your window choice should be justified by measurable performance improvements and cost savings.
Understanding Melbourne’s Climate Demands
Melbourne experiences approximately 2,500 heating degree days and 400 cooling degree days annually—meaning we spend far more energy heating our homes than cooling them. This climate profile significantly affects the value proposition of different glazing options.
Double glazing typically achieves a U-value of 2.0-2.8 W/m²K, which represents good thermal performance for Melbourne’s climate. This means that for every square meter of window, you’re losing 2.0-2.8 watts of heat per degree of temperature difference between inside and outside.
Triple glazing achieves U-values of 0.8-1.2 W/m²K—representing approximately 50-60% better insulation than double glazing. In practical terms, this means less heat escapes during winter and less heat enters during summer.
Real-World Energy Savings
Based on our installations across Melbourne and subsequent energy bill analysis, here’s what homeowners typically experience:
Double glazing reduces heating and cooling costs by 20-30% compared to single-pane windows in an average Melbourne home. For a typical household spending 1,800 annually on heating and cooling, that′s1,800 annually on heating and cooling, that’s 360-540 in annual savings.
Triple glazing reduces costs by 35-45% compared to single panes—or roughly 15-20% better than double glazing. That translates to an additional $150-200 in annual savings over double glazing.
The payback period matters. If double glazing costs 15,000foranaveragehomeandsaves15,000 for an average home and saves 450 annually, you’re looking at a 33-year payback purely on energy savings. Triple glazing at 24,000with24,000 with 600 annual savings has a 40-year payback.
However, this calculation misses several important factors. Comfort improvements have real value that’s hard to quantify. Not having to wear three layers indoors during July, or enjoying your north-facing living room during January without the air conditioner running constantly—these quality-of-life improvements matter.
Victorian Government Incentives
The Victorian Energy Upgrades (VEU) program provides rebates for energy-efficient window installations, though eligibility depends on specific circumstances. We’ve helped hundreds of Melbourne families access these incentives, which can reduce the upfront cost of double glazing by $1,000-2,000.
Currently, triple glazing doesn’t qualify for additional rebates beyond what double glazing receives, which affects the comparative value proposition. However, this could change as the government updates energy efficiency standards.
The Carbon Footprint Consideration
In our experience working across Melbourne suburbs, environmentally conscious homeowners increasingly factor in carbon emissions when making renovation decisions.
Double glazing typically prevents 1-1.5 tones of CO2 emissions annually in an average Melbourne home by reducing heating and cooling requirements. Triple glazing prevents approximately 1.5-2 tonnes annually—a meaningful difference for those prioritizing environmental impact.
How Much Do Double Glazed Windows Cost in Melbourne?
Let’s cut through the marketing fluff and talk real numbers. Window costs vary dramatically based on size, style, frame material, and installation complexity—but here are realistic ranges based on our Melbourne installations.
Double Glazed Window Costs
Standard double hung windows (1200mm x 1500mm):
- Aluminium frames: $1,200-1,800 per window installed
- Timber frames: $1,800-2,500 per window installed
- uPVC frames: $1,400-2,000 per window installed
Sliding windows (2400mm x 1800mm):
- Aluminium: $2,200-3,200 per window
- Timber: $3,000-4,200 per window
- uPVC: $2,500-3,500 per window
For an average three-bedroom Melbourne home (approximately 12-15 windows), expect to invest $15,000-25,000 for complete double glazing installation with quality materials.
Triple Glazed Window Costs
Triple glazing typically costs 40-60% more than comparable double glazing:
Standard double hung windows (1200mm x 1500mm):
- Aluminium frames: $1,800-2,600 per window installed
- Timber frames: $2,600-3,600 per window installed
- uPVC frames: $2,000-2,800 per window installed
For the same three-bedroom Melbourne home, triple glazing installation ranges from $24,000-38,000.
What Affects Your Final Cost?
Several factors significantly impact your final investment:
Suburb location matters. Installation costs in inner Melbourne suburbs like South Yarra and Prahran run 10-15% higher than outer suburbs due to access challenges, parking restrictions, and higher labor rates.
Heritage requirements add cost. If you’re in a heritage overlay area (common in Hawthorn, Kew, and Malvern East), custom manufacturing to match existing window profiles can increase costs by 20-30%.
Frame material choice is significant. Timber frames cost more but offer superior aesthetics for period homes. Aluminium provides durability and modern looks at mid-range prices. uPVC offers excellent insulation at competitive prices but may not suit all architectural styles.
Installation complexity varies dramatically. Ground floor windows with easy access cost less to install than second-story windows requiring scaffolding. Removing old windows from brick veneer homes is simpler than extraction from double-brick period homes.
Financing Options
Dena Windows and Doors offers flexible payment plans that allow Melbourne homeowners to spread costs over 12-60 months, making premium glazing more accessible. Many customers choose to upgrade in stages—starting with living areas and bedrooms, then completing secondary spaces over time.
Long-Term Return on Investment
Property valuers suggest that quality window upgrades add 60-80% of their cost to property values in Melbourne’s current market. Premium triple glazing in high-end suburbs may return 90-100% of costs, while double glazing in growth corridors typically returns 50-70%.
Beyond resale value, the lifestyle improvements justify the investment for most Melbourne families. Better sleep quality, improved comfort, reduced noise stress, and lower energy bills create daily value that compounds over years of ownership.
Frequently Asked Questions About Double and Triple Glazed Windows in Melbourne
Are triple glazed windows worth it in Melbourne?
For most Melbourne homes, triple glazing delivers diminishing returns compared to double glazing. Our climate simply doesn’t experience the extreme cold that makes triple glazing essential in places like Canberra or Hobart.
However, triple glazing is worth considering if you:
- Live in elevated areas like the Dandenong Ranges or Yarra Valley
- Have a home on a busy arterial road requiring maximum noise reduction
- Own a heritage property where you can’t add external insulation
- Plan to stay in your home for 15+ years to realize the full payback
- Prioritize absolute comfort over cost-effectiveness
- Are building or renovating a high-end property where it’s expected
Get your personalized window assessment from Dena to determine whether triple glazing makes financial sense for your specific situation.
How much can I save with double glazed windows?
Based on analysis of our Melbourne installations, homeowners typically save $350-600 annually on combined heating and cooling costs after upgrading from single-pane to double glazed windows.
The savings vary significantly based on:
- Your home’s size and existing insulation levels
- How much north-facing glass you have
- Your heating and cooling habits
- Local electricity and gas rates
- Your suburb’s microclimate
A Footscray family home we upgraded in 2023 reduced energy bills by 28%—from 2,100 to 2,100 to 1,512 annually, creating 588 in annual savings. At that rate, their 588 in annual savings. At that rate, their 18,500 investment will pay back in approximately 31 years through energy savings alone.
However, they also reported sleeping better (no more street noise), eliminating condensation problems, and feeling comfortable enough to reduce heater usage by several hours daily—quality-of-life improvements that justify the investment beyond pure financial returns.
Do I need triple glazing in Melbourne?
No, you don’t need triple glazing in Melbourne. Double glazing provides excellent performance for our climate and represents better value for most homeowners.
Consider triple glazing only if:
- Noise reduction is your primary concern (you live on a major road)
- You’re in an extremely cold microclimate (hills, ranges, elevated areas)
- Budget isn’t a primary constraint
- You’re renovating a heritage home where you can’t add wall insulation
- You want absolute best-in-class performance
Dena Windows and Doors recommends double glazing for 80% of Melbourne homes, with triple glazing reserved for specific circumstances where the additional performance justifies the extra cost.
What’s the difference between double and triple glazing?
The fundamental difference is simple: double glazing has two panes of glass with one air gap, while triple glazing has three panes with two air gaps.
Performance differences:
- Thermal insulation: Triple glazing is 40-50% better than double glazing
- Noise reduction: Triple glazing blocks approximately 20% more sound
- UV protection: Similar with low-E coatings on both
- Condensation control: Triple glazing virtually eliminates it in all Melbourne conditions
- Weight: Triple glazing is approximately 50% heavier, requiring stronger frames
- Cost: Triple glazing costs 40-60% more than double glazing
In Melbourne’s climate, double glazing delivers 80% of triple glazing’s benefits at 60% of the cost—which is why it remains our most popular recommendation.
How long do double glazed windows last?
Quality double glazed windows from Dena Windows and Doors typically last 20-25 years with minimal maintenance. The sealed units maintain their insulating properties throughout this period, provided they’re properly installed.
Factors affecting lifespan:
- Frame material: Aluminium and uPVC frames last 25-30 years; timber requires more maintenance but can last 30-40 years with proper care
- Installation quality: Poor installation reduces lifespan significantly
- Environmental exposure: Coastal homes face more corrosion; north-facing windows experience more UV exposure
- Maintenance: Regular cleaning and hardware lubrication extends lifespan
We’ve installed over 10,000 windows across Victoria, and our warranty reflects our confidence: 10 years on sealed units, 7 years on hardware, lifetime on frames. Many customers report their windows performing perfectly after 15-20 years.
Are double glazed windows noisy in Melbourne?
This is a common misconception. Double glazed windows are significantly quieter than single-pane windows—reducing external noise by 30-50 decibels depending on glass thickness and air gap size.
If you’re experiencing noise with double glazing, possible causes include:
- Incorrect installation leaving gaps around frames
- Inadequate sealing
- Single-glazed sections (like vents) undermining overall performance
- Unrealistic expectations (no window eliminates all noise)
Many Melbourne homeowners ask us about noise after installation, and usually the issue relates to other paths for sound entry—doors, vents, ceiling spaces, or wall cavities. Windows are just one component of acoustic control.
For extreme noise situations (major arterials, near airports), triple glazing or acoustic laminated glass in double glazed units provides superior performance. See how Dena can transform your home with a customized acoustic solution for your specific noise challenges.
Real Melbourne Success Stories: Double and Triple Glazing in Action
Nothing illustrates the real-world impact of quality windows better than actual installations across Melbourne suburbs. Here are three recent projects that showcase different approaches to the double-versus-triple glazing decision.
Toorak Heritage Renovation: How Triple Glazing Preserved Character While Delivering Modern Comfort
A 1920s Toorak mansion presented a classic Melbourne dilemma: heritage overlay restrictions prevented external insulation upgrades, but the original single-pane windows made the home virtually uninhabitable during winter despite a $15,000 annual heating bill.
The solution: Custom triple glazed windows manufactured to exactly match the original window profiles, including authentic divided lights and heritage hardware. The frames were powder-coated to match the original finish, making the upgrade invisible from the street.
Results after one year:
- Heating costs dropped from 15,000to15,000 to 8,200 annually
- Interior temperature stability improved by 6-8 degrees
- Street noise reduced by approximately 55 decibels
- Heritage Victoria approved the installation as sympathetic to original character
- Property valuation increased by $180,000, partially attributed to the window upgrade
The homeowner’s feedback: “We can finally use our front rooms during winter. The temperature stays consistent, there’s no condensation on the glass, and we can actually have conversations without shouting over traffic noise from Toorak Road. The investment was significant, but it’s transformed how we live in this house.”
This project demonstrates when triple glazing justifies its premium cost—heritage constraints, high energy costs, and long-term ownership plans aligned to make it the optimal choice.
Footscray Family Home: Double Glazing Reduced Energy Bills by 25% While Improving Livability
A young family in Footscray faced typical challenges: a 1960s brick veneer home with aluminum single-pane windows that leaked air, created condensation problems, and did nothing to block noise from nearby Hopkins Street.
The solution: Complete double glazing upgrade using thermally broken aluminum frames with argon-filled sealed units. The project included 14 windows and two sliding doors, completed over three days with minimal disruption.
Results after 18 months:
- Combined heating and cooling costs dropped 25% (from 1,680to1,680 to 1,260 annually)
- Condensation eliminated entirely, preventing mold growth in bedrooms
- Street noise reduced by approximately 35 decibels
- Resale value increased by an estimated $25,000-30,000
- Total investment: $17,800
The homeowner’s perspective: “We initially considered triple glazing but decided the extra cost wasn’t justified for our situation. Eighteen months later, we’re confident we made the right choice. The house is so much more comfortable, our kids sleep better, and we’re saving enough on energy bills to justify the investment. For a young family on a budget, double glazing was the smart decision.”
This installation showcases double glazing’s excellent value proposition for typical Melbourne homes—delivering substantial improvements at a price point that makes financial sense for families balancing multiple priorities.
Beaumaris Bayside Property: Salt-Resistant Triple Glazing Solution Solved Corrosion Challenges
A modern Beaumaris home just 200 meters from Port Phillip Bay suffered from accelerated window deterioration due to salt air exposure. The original aluminum windows showed significant corrosion after just eight years, and the homeowners wanted a long-term solution that wouldn’t require replacement within a decade.
The solution: Marine-grade triple glazed windows with specialized coastal coatings, stainless steel hardware, and enhanced sealing systems designed specifically for harsh coastal environments.
Results after three years:
- Zero corrosion or deterioration despite direct salt air exposure
- Interior temperature moderation improved dramatically (the bay breeze previously made winter heating inefficient)
- UV protection prevented further fading of internal furnishings
- Noise from Beach Road traffic reduced by 50 decibels
- Total investment: $32,000 for complete home upgrade
The homeowner’s assessment: “Living this close to the bay, we knew we needed something special. The triple glazing with marine-grade treatments costs more upfront, but we’re confident these windows will last 25-30 years without the corrosion problems we experienced before. The comfort improvement is remarkable—we can actually enjoy our bay views without fighting temperature extremes and noise.”
This project illustrates how environmental factors sometimes justify premium solutions—the coastal location created specific challenges that triple glazing’s additional sealing and protection addressed effectively.
What These Stories Reveal
The common thread across all three installations: the “right” choice depends entirely on individual circumstances. Toorak’s heritage constraints, Footscray’s budget priorities, and Beaumaris’s environmental challenges each pointed toward different optimal solutions.

Making Your Decision: Double or Triple Glazing for Your Melbourne Home?
After exploring the technical details, costs, and real-world applications, how do you actually make this decision for your home?
Start With Your Priorities
Choose double glazing if:
- Budget is a primary concern
- You live in moderate climate areas (most of Melbourne)
- You’re renovating to sell within 5-10 years
- Your home has good existing insulation
- You want excellent performance at reasonable cost
- You’re in outer suburbs where property values don’t justify premium upgrades
Choose triple glazing if:
- Maximum performance is your priority
- You live in cold microclimates (hills, ranges, elevated areas)
- Noise reduction is critical (major roads, airports)
- You’re in a heritage home where you can’t add wall insulation
- Budget isn’t a primary constraint
- You plan long-term ownership (15+ years)
- You’re building or renovating a prestige property
Consider a Hybrid Approach
Many Melbourne homeowners ask us about combining both options—and it’s often the smartest strategy.
Typical hybrid configurations:
- Triple glazing in living areas and main bedrooms (where you spend most time)
- Double glazing in secondary bedrooms, bathrooms, and utility areas
- Triple glazing on noisy street-facing windows, double glazing elsewhere
- Premium glazing in ground floor (security and noise), standard glazing upstairs
This approach optimizes performance where it matters most while managing overall costs—often delivering 90% of full triple glazing’s benefits at 70% of the cost.
Don’t Forget the Bigger Picture
Windows are just one component of home energy efficiency. Before investing $20,000-30,000 in premium glazing, ensure you’ve addressed:
- Ceiling insulation (often the best ROI for Melbourne homes)
- Wall insulation (if accessible and practical)
- Door seals and draft proofing
- Efficient heating and cooling systems
- Appropriate shading (particularly for north and west-facing windows)
Dena Windows and Doors recommends a whole-home approach to energy efficiency. We’re happy to assess your property and suggest whether windows should be your first priority or whether other improvements might deliver better value.
