This might lead you to turn on lights, which will lead to greater energy costs. Conduction is how readily a product carries out heat. This is known as the U value. The U worth 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 circulation and the much 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, the heat loss through the windows would be: 6. 2 15 70 = 6510W That is equivalent to the total heat output of a large space gas heating system or a 6.
