uPVC frames for double and triple glazed units work by being made up of multiple chambers of air within the frame. The use of these multiple chambers allows more heat to be trapped within the frame resulting in improved thermal efficiency for your home. Thermal efficiency describes how effective a particular material is as a heat insulator and is measured in the energy in Watts (W) lost per square meter of the material (m2). This provides us with a U-Value. The lower the U-value, the better, as this means less heat is passing through your window frames. This will help to keep your energy bills down as you will need to spend less on heating your home.
