Energy-efficient glazing makes your house more comfy and drastically minimizes your energy expenses. Inappropriate or improperly developed glazing can be a major source of undesirable 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 acquired and up to 40% lost through windows.

Glazing is a significant investment in the quality of your house. The expense of glazing and the cost of heating and cooling your home are closely associated. An initial financial investment in energy-efficient windows, skylights and doors can considerably decrease your annual cooling and heating costs.

Secret homes of glass Source: Adapted from the Australian Window Association The quantity of light that passes through the glazing is called visible light transmittance (VLT) or noticeable transmittance (VT).

This might lead you to change on lights, which will lead to higher energy costs. Conduction is how readily a product performs heat. This is known as the U worth. 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 greater a window's resistance to heat circulation and the much better its insulating value.

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 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 (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 transfers to the home interior. The real SHGC for windows is impacted 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 manufacturers is constantly calculated as having a 0 angle of occurrence. As the angle increases, more solar radiation is shown, and less is transmitted.
