This may lead you to change on lights, which will lead to higher energy expenses. Conduction is how easily a product conducts heat. This is referred to as the U worth. The U value for windows (expressed 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 circulation and the better its insulating value.

If your home 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 to 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 heater or a 6.
