Thermal Break Window
Built for Australia's 7-star future
Aluminium conducts heat. Left alone, a metal frame becomes a thermal bridge: warmth leaves the room in winter, comes back in summer. A thermal break splits the frame internally with a reinforced polyamide bar, so the inside face stays close to room temperature.
We supply premium thermal-broken frames in our CWD100 series — double-glazed as standard, tuned for Canberra winters and Sydney summers.
The difference is in the detail.
A more efficient room.
Less heat lost through the frame in winter, less gained in summer. Lower heating and cooling load, lower running costs.
No more cold-spots.
The inside face of the frame stays close to room temperature, so the air near the window feels the same as the rest of the room.
Less condensation.
A warm inside frame doesn't pull moisture out of the air. Less fog on the glass, dry sills, longer-lived joinery.
When a thermal break earns its keep.
Canberra winters: every degree of warmth lost through a cold frame in July is a heating bill paid in August.
Sydney summers: heat gain through bare aluminium pushes the air-conditioning hard. A thermal break flattens the peak.
New builds: a straightforward way to push the NatHERS rating up without compromising on glass area.
Renovations: one of the highest-return upgrades you can make to an older home for thermal comfort.
