Comprehending some of the essential properties of glass will help you to choose the finest glazing for your home.

This might lead you to change on lights, which will lead to higher energy expenses. Conduction is how easily a material performs heat. This is called the U value. The U worth for windows (expressed as Uw), describes 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 value.

If your house has 70m2 of glazing with aluminium frames and clear glass with a U value of 6. 2W/m2 C, on a winter season's night when it is 15C cooler outside compared to inside your home, the heat loss through the windows would be: 6. 2 15 70 = 6510W That is equivalent to the total heat output of a big room gas heater or a 6.

If you choose a window with half the U value (3. 1W/m2 C) (for instance, double glazing with an argon-filled space and less-conductive frames), you can cut in half the heat loss: 3. 1 15 70 = 3255W The solar heat gain coefficient (SHGC) for windows (revealed as SHGCw) determines how easily heat from direct sunlight flows through an entire window (glass and frame together).

The lower a window's SHGC, the less solar heat it transfers to the house interior. The real SHGC for windows is affected by the angle that solar radiation strikes the glass.

When the sun is perpendicular (at 90) to the glass, it has an angle of incidence of 0 and the window will experience the optimum possible solar heat gain. The SHGC stated by glazing producers is constantly determined as having a 0 angle of occurrence. As the angle increases, more solar radiation is reflected, and less is transmitted.
