What Are Thermally Broken Windows?
Thermally broken windows use a polyamide thermal barrier between the interior and exterior aluminium frames. This simple engineering innovation stops heat from conducting through the metal, dramatically improving insulation.
Without a thermal break, standard aluminium frames act like a bridge for heat and cold. In winter, warm air escapes. In summer, heat floods in. With a thermal break, that transfer stops, keeping your home comfortable year-round.
Real Energy Savings
Our SoTherm ALUMINIUM systems achieve U-values of 1.6 to 2.4 W/m²K with double glazing, with triple glazing lower again. The lower the U-value, the better the insulation.
Homeowners who upgrade from single-glazed aluminium to thermally broken double glazing see heating and cooling costs drop by 30-40%. That's hundreds of dollars saved every year, plus improved comfort in every room.
No More Condensation
Condensation happens when warm indoor air hits cold window frames. Over time, it leads to mould, damaged sills, and poor air quality.
Thermally broken frames stay warm on the inside, even in Melbourne's coldest mornings. That means no more wiping windows, no more damp curtains, and no more mould growth around frames.

A 1920s Californian bungalow needed sympathetic window replacement. We used SoTherm triple glazed systems to match original proportions while achieving modern energy performance.
Hampton: New Build Luxury Home
Floor-to-ceiling thermally broken sliding doors with SoTherm sliding systems delivered exceptional thermal performance without compromising the minimalist aesthetic.

We upgraded an entire 1980s home with SoTherm double glazed windows. The transformation included improved street appeal and a 40% drop in energy consumption.
Why Choose Thermally Broken Over Standard Aluminium?
Standard aluminium windows are strong, durable, and low-maintenance. But without a thermal break, they're one of the least energy-efficient options available.
Thermally broken windows give you all the benefits of aluminium: slim frames, the full Dulux colour range, long lifespan with the insulation performance of timber or uPVC. It's the best of both worlds.
If you're building new or replacing existing windows, thermally broken aluminium is the smartest choice for Melbourne's climate.
