Energy-efficient glazing makes your house more comfortable and dramatically decreases your energy costs. Nevertheless, unsuitable or improperly created glazing can be a major source of unwanted heat gain in summer and substantial heat loss and condensation in winter season. As much as 87% of a home's heating energy can be gained and as much as 40% lost through windows.

This tool compares window selections to a base level aluminium window with 3mm clear glass. Understanding some of the essential homes of glass will assist you to select the very best glazing for your home. Key properties of glass Source: Adapted from the Australian Window Association The quantity of light that goes through the glazing is known as noticeable light transmittance (VLT) or noticeable transmittance (VT).

This may lead you to turn on lights, which will lead to higher energy costs. Conduction is how easily a product carries out heat. This is called the U worth. The U value for windows (revealed 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 circulation and the better its insulating worth.

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 season's night when it is 15C colder outside compared with inside, the heat loss through the windows would be: 6. 2 15 70 = 6510W That is comparable to the total heat output of a big room gas heating unit or a 6.

If you pick a window with half the U worth (3. 1W/m2 C) (for example, double glazing with an argon-filled gap 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) 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 transmits to your home interior. Glazing producers state an SHGC for each window type and style. The real SHGC for windows is affected by the angle that solar radiation strikes the glass. This is called the angle of incidence.

The Science Behind Double Glazed Windows in Swan View WA

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 producers is always determined as having a 0 angle of incidence. As the angle increases, more solar radiation is shown, and less is sent.
