Reduce your heating costs

Save energy with thermal insulation

Are your heating costs too high? Normally, this is in fact down to your windows, not your heating system.

In Australia’s diverse climate, from hot coastal summers to cool inland winters efficient windows and doors make all the difference. aluplast uPVC systems are designed to deliver outstanding thermal performance, helping homes stay cooler in summer and warmer in winter while reducing energy consumption and household bills.

uPVC is approximately 1,000 times less thermally conductive than aluminium. Traditional aluminium frames can act as thermal bridges, allowing heat and cold to pass easily through. aluplast’s advanced uPVC profiles are different. Engineered with multiple internal chambers, they trap air within the frame to create a natural barrier against temperature transfer. Combined with high-quality compression seals and precision gaskets, aluplast systems achieve excellent insulation and airtightness,  essential for comfort and efficiency in Australian homes.

While just 8% of a building's outer shell is made up of windows, they are the source of almost 40% of heat losses.

The thermal imaging camera shows one thing for certain: High surface temperatures and, as a result, significant heat losses are visible in the area around the glass and frame before the renovation with aluplast – as you can see from the red and yellow areas. After replacing the windows, heat losses are kept to a minimum.

Every aluplast window and door system is compatible with double or triple glazing, low-e coatings, and gas-filled units to further enhance performance. This combination minimises heat loss in winter and solar gain in summer, helping to stabilise indoor temperatures and reduce reliance on heating and cooling systems.

Key benefits include:
• Lower energy bills and improved comfort year-round
• Reduced drafts, hot spots, and condensation
• Easier compliance with energy standards such as NatHERS

Durable, Sustainable Performance
Unlike materials that corrode, warp, or require regular maintenance, aluplast uPVC retains its shape and performance over time — ensuring your home remains energy efficient for decades. And as part of Australia’s first local uPVC recycling programme, aluplast is closing the loop on sustainability by reprocessing offcuts and old frames into new, high-quality materials.

A Smarter Choice for Every Project
Whether building new or renovating, aluplast systems offer the perfect balance of energy efficiency, modern design, and long-term reliability. With stylish surface finishes like woodec and aludec, you can achieve the look you want without compromising on performance.
