APS Double Glazing has been awarded Second Place at the World Sustainability Awards — a global honour recognising businesses leading the way in environmental responsibility and circular manufacturing. Our approach to sustainability covers everything from recycled materials and carbon reduction through to the energy performance of every window we install.
While Melbourne is Australia’s fastest-growing capital city, the majority of our housing stock is ageing. Historically low building costs have left most Victorian homes with an energy rating far below current standards — and old windows are one of the biggest culprits.
Single-glazed windows are responsible for approximately 40% of a home’s thermal energy loss in winter, and heat gain in summer. Glass conducts heat far more readily than walls and roofs, making your windows the weakest point in your home’s thermal envelope.
With energy costs rising year after year, sustainable high-performance double glazing isn’t just an environmental choice — it’s a financial one. APS helps Melbourne homeowners address both problems with a single upgrade.
Thermally efficient sealed units keep conditioned air inside, dramatically cutting heating and cooling costs year-round.
Less household energy consumed means fewer greenhouse gas emissions — a direct contribution to a healthier planet.
uPVC can be recycled up to 10 times without losing structural integrity — one of the most sustainable building materials available.
Advanced acoustic glass and airtight seals block traffic, tram, and neighbourhood noise for a quieter, more comfortable home.
uPVC never fades, cracks, warps, or needs repainting. No toxic paints or chemical treatments — ever.
Engineered for conditions ranging from 40°C summer heatwaves to freezing winter mornings — without degrading.
Sustainability at APS isn’t a single initiative — it’s built into three interconnected pillars that cover how we source materials, how we manufacture, and how our products perform for decades after installation.
We incorporate recycled uPVC into our manufacturing and operate dedicated recycling stations for offcuts, glass, steel, and packaging. Our lead-free profiles use environmentally responsible stabilisers. Learn more about our recycling practices →
Every APS window is custom-built in our Australian factory — eliminating overseas shipping emissions, reducing material waste from standard sizing, and keeping skilled manufacturing jobs in Australia.
Our double-glazed uPVC windows reduce household energy consumption by up to 40% — and maintain that performance for 30+ years with zero maintenance. Across 250+ homes, the cumulative carbon savings are substantial.
The concept is straightforward: two panes of glass are sealed together with an insulating gas filling the void between them. This sealed unit dramatically reduces the transfer of heat through the window — keeping your home cooler in summer and warmer in winter.
APS takes this further with European-designed uPVC frame profiles that incorporate multiple insulating chambers within the frame itself. Combined with premium Low-E glass and argon gas fills, the result is a window system that outperforms standard double glazing by a significant margin.
Most Melbourne single-glazed windows have a U-value of around 10. APS’s units achieve dramatically lower U-values — meaning your heating and cooling systems work a fraction as hard. Lower energy use, lower bills, lower emissions.
The cost varies depending on the number and size of windows, the glass specification, and the structural work involved. What most homeowners discover is that double glazed windows and doors pay for themselves over time through reduced energy bills, lower maintenance costs, and improved property value.
Research from the University of Melbourne found that in some Melbourne suburbs, it could take as little as nine years to recoup the costs of improving a home’s energy rating — and APS windows last 30+ years with zero maintenance.
APS uPVC double glazed windows exceed Australian Window Energy Rating Scheme standards, delivering real, measurable savings from the very first energy bill after installation.
Not all double glazing is created equal. APS windows and doors are manufactured to meet and exceed Australian Standards AS2047 and AS1288, and are WERS certified for energy performance.
Every unit features German-engineered uPVC profiles, premium Low-E glass as standard, fully reinforced galvanised steel, hot-plate welded frames, and German multi-point locking systems — all manufactured locally in our Australian factory.
As a registered building practitioner with over 20 years of experience, APS provides full insurance coverage and compliance guarantees on every installation.
Our commitment to recycled materials, local manufacturing, and energy-efficient products earned APS global recognition at the World Sustainability Awards. Read the full story of our award journey →
When a Melbourne family installs APS double glazing, they’re cutting energy waste, lowering emissions, and supporting a circular manufacturing system that keeps materials in use and out of landfill.
