This may lead you to turn on lights, which will result in higher energy costs. Conduction is how readily a material performs heat. This is understood as the U worth. The U worth for windows (expressed as Uw), describes the conduction of the entire window (glass and frame together). The lower the U worth, the greater a window's resistance to heat flow and the better its insulating value.

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 with inside your home, 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 heating system 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 impacted by the angle that solar radiation strikes the glass.

When the sun is perpendicular (at 90) to the glass, it has an angle of incidence of 0 and the window will experience the optimum possible solar heat gain. The SHGC declared by glazing manufacturers is always determined as having a 0 angle of occurrence. As the angle increases, more solar radiation is shown, and less is transferred.
