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.
