RH Hinged CRT2007 Series
RH Hinged serie with termal break
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. Thermal window and door systems offer substantially improved insulation properties for the building envelope as well as greater resistance to solar heat gain. 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.
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 right shows how the insulation properties of Thermal 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. Thermal window and door systems provide excellent insulation minimising the transfer of heat or cold between the internal and external environment.
Solar Heat Gain Coefficient
SHGC is a measure of how much solar radiation passes through a window. Thermal 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 Thermal windows based on climate zone.
