The U value for windows (revealed as Uw), explains the conduction of the whole window (glass and frame together). The lower the U value, the higher a window's resistance to heat flow and the better its insulating worth.

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 season'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 comparable to the overall heat output of a large room gas heater or a 6.

The lower a window's SHGC, the less solar heat it transmits to the house interior. Glazing makers state an SHGC for each window type and style. However, the actual SHGC for windows is affected by the angle that solar radiation strikes the glass. This is understood as the angle of occurrence.

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 makers is constantly calculated as having a 0 angle of incidence. As the angle increases, more solar radiation is reflected, and less is transmitted.
