This may lead you to turn on lights, which will lead to higher energy expenses. Conduction is how readily a product conducts heat. This is called the U worth. The U value for windows (expressed as Uw), explains the conduction of the entire window (glass and frame together). The lower the U value, the higher a window's resistance to heat circulation and the much better its insulating value.

If your home has 70m2 of glazing with aluminium frames and clear glass with a U worth of 6. 2W/m2 C, on a winter season'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 overall heat output of a large space gas heating unit or a 6.
