This may lead you to turn on lights, which will result in higher energy costs. Conduction is how readily a product carries out heat. This is referred to as the U value. The U value for windows (revealed as Uw), describes the conduction of the whole window (glass and frame together). The lower the U worth, the higher a window's resistance to heat flow and the much better its insulating value.

If your house has 70m2 of glazing with aluminium frames and clear glass with a U value of 6. 2W/m2 C, on a winter's night when it is 15C chillier outside compared with inside, the heat loss through the windows would be: 6. 2 15 70 = 6510W That is comparable to the overall heat output of a large room gas heater or a 6.

The lower a window's SHGC, the less solar heat it sends to the house interior. The actual SHGC for windows is affected by the angle that solar radiation strikes the glass.

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.
