This may lead you to change on lights, which will lead to greater energy costs. Conduction is how readily a product performs heat. This is called the U value. The U worth for windows (expressed as Uw), explains the conduction of the entire window (glass and frame together). The lower the U worth, the greater a window's resistance to heat circulation 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's night when it is 15C chillier outside compared to indoors, 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 heating system or a 6.

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

The lower a window's SHGC, the less solar heat it sends to the house interior. Glazing producers declare an SHGC for each window type and style. Nevertheless, the real SHGC for windows is impacted by the angle that solar radiation strikes the glass. This is referred to as the angle of incidence.

Is Double Glazing Worth It? in South Perth Perth

When the sun is perpendicular (at 90) to the glass, it has an angle of incidence of 0 and the window will experience the maximum 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.
