Energy-efficient glazing makes your house more comfortable and significantly reduces your energy costs. Inappropriate or improperly developed glazing can be a significant source of unwanted heat gain in summertime and considerable heat loss and condensation in winter season. Up to 87% of a house's heating energy can be gained and approximately 40% lost through windows.

Glazing is a substantial financial investment in the quality of your house. The expense of glazing and the expense of heating and cooling your house are carefully associated. An initial financial investment in energy-efficient windows, skylights and doors can greatly decrease your yearly heating and cooling bill.

Understanding some of the key properties of glass will help you to choose the very best glazing for your home. Key homes of glass Source: Adapted from the Australian Window Association The quantity of light that goes through the glazing is called visible light transmittance (VLT) or noticeable transmittance (VT).

Why Do You Need Double Glazing Windows In Summer? in Westminster Western Australia

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 circulation and the better its insulating worth.

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's night when it is 15C colder outside compared to inside, the heat loss through the windows would be: 6. 2 15 70 = 6510W That is equivalent to the overall heat output of a big space gas heating system 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 space and less-conductive frames), you can halve the heat loss: 3. 1 15 70 = 3255W The solar heat gain coefficient (SHGC) for windows (expressed as SHGCw) determines how readily heat from direct sunlight flows through a whole window (glass and frame together).

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 design. Nevertheless, the actual SHGC for windows is affected by the angle that solar radiation strikes the glass. This is referred to as the angle of incidence.

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 manufacturers is constantly determined as having a 0 angle of incidence. As the angle increases, more solar radiation is reflected, and less is sent.
