Thermal Break Technology


Energy efficient window and door systems are an important part of any green building project. Thermally broken aluminium window and door systems deliver a number of benefits for green building. ThermalHEART™ window and door systems offer substantially improved insulation properties for the building envelope as well as greater resistance to solar heat gain. ThermalHEART™ thermally broken aluminium window and door systems provide an energy efficient alternative to traditional non-thermally broken aluminium window and door products, helping you maximise efficiency and comfort within your projects.

Insulation

The insulation properties of a window are measured as a U-value. The U-value provides and indication of how much heat energy is transferred through a window. The lower the U-value, the better the window is at keeping the heat or cold out.

The illustration shows how the insulation properties of ThermalHEART™ window and door systems, combined with appropriate glass selection, improve the U-value and window performance in a cold climate. The principles would operate in reverse in a warm climate. ThermalHEART™ window and door systems provide excellent insulation minimising the transfer of heat or cold between the internal and external environment.

We believe high performance, thermally efficient windows and doors have an important role to play in a sustainable future

Solar Heat Gain Coefficient

SHGC is a measure of how much solar radiation passes through a window. ThermalHEART™ systems drastically reduce solar heat gain through the window frame. Varying levels of solar radiation will still pass through the glass, offering passive solar heating. Appropriate glass selection will ensure the optimum performance of ThermalHEART™ windows based on climate zone.
