Energy Efficiency


“In testing, based on an average house containing 8% area of glazing in the entire building fabric (windows, walls, floor and roof), as much as 49% of the heat lost during winter and as much as 87% of the heat gained during summer can come from the windows.”


We are now, more than ever, conscious of the need to save energy within our homes. Windows have a major impact on the energy efficiency of your home, with up to 40% of a home’s energy for cooling or heating being lost or gained through windows.

Improving your aluminium windows and doors’ thermal performance and energy efficiency reduces your home’s energy costs. This can be done by selecting the right frame and glass for the position of the window. For maximum performance, the ThermalHEART range of windows and doors is a market leading

To help you out with this selection process, all of our aluminium window and door systems are rated by the Window Energy Rating Scheme (WERS). This functions very similarly to the ratings you see on whitegoods and is the standard by which thermal efficiency is measured in Australian windows and doors.
