The U value for windows (revealed as Uw), describes the conduction of the whole window (glass and frame together). The lower the U value, the higher a window's resistance to heat flow and the much better its insulating worth.

If your house has 70m2 of glazing with aluminium frames and clear glass with a U worth of 6. 2W/m2 C, on a winter's night when it is 15C colder outside compared to indoors, the heat loss through the windows would be: 6. 2 15 70 = 6510W That is equivalent to the total heat output of a large room gas heating system or a 6.

If you pick a window with half the U value (3. 1W/m2 C) (for example, double glazing with an argon-filled space and less-conductive frames), you can halve the heat loss: 3. 1 15 70 = 3255W The solar heat gain coefficient (SHGC) for windows (expressed as SHGCw) measures how readily heat from direct sunshine flows through a whole window (glass and frame together).

The lower a window's SHGC, the less solar heat it sends to your home interior. Glazing makers declare an SHGC for each window type and style. The actual SHGC for windows is impacted by the angle that solar radiation strikes the glass. This is known as the angle of occurrence.

When the sun is perpendicular (at 90) to the glass, it has an angle of occurrence of 0 and the window will experience the maximum possible solar heat gain. The SHGC stated by glazing manufacturers is constantly computed as having a 0 angle of occurrence. As the angle increases, more solar radiation is shown, and less is transmitted.
