This may lead you to switch on lights, which will lead to greater energy expenses. Conduction is how easily a product performs heat. This is known as the U worth. The U worth for windows (expressed as Uw), explains the conduction of the whole window (glass and frame together). The lower the U worth, the greater a window's resistance to heat circulation 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 cooler outside compared to indoors, 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.

When the sun is perpendicular (at 90) to the glass, it has an angle of incidence of 0 and the window will experience the maximum possible solar heat gain. The SHGC stated by glazing makers is always determined as having a 0 angle of incidence. As the angle increases, more solar radiation is reflected, and less is sent.
