This may lead you to turn on lights, which will lead to greater energy costs. Conduction is how readily a material performs heat. This is called the U value. 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 higher a window's resistance to heat circulation and the much better its insulating value.

For example, 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 chillier outside compared with 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 room gas heater or a 6.

The lower a window's SHGC, the less solar heat it transfers to the home 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 occurrence of 0 and the window will experience the optimum possible solar heat gain. The SHGC declared by glazing manufacturers is constantly determined as having a 0 angle of occurrence. As the angle increases, more solar radiation is reflected, and less is sent.
