Energy-efficient glazing makes your home more comfortable and drastically reduces your energy expenses. Unsuitable or improperly developed glazing can be a significant source of undesirable heat gain in summer and considerable heat loss and condensation in winter season. Approximately 87% of a home's heating energy can be gained and approximately 40% lost through windows.

Why Do You Need Double Glazing Windows In Summer? in Martin WA

Glazing is a substantial financial investment in the quality of your house. A preliminary financial investment in energy-efficient windows, skylights and doors can significantly reduce your annual heating and cooling bill.

This tool compares window choices to a base level aluminium window with 3mm clear glass. Understanding some of the key homes of glass will help you to select the very best glazing for your home. Key homes of glass Source: Adapted from the Australian Window Association The amount of light that travels through the glazing is called visible light transmittance (VLT) or visible transmittance (VT).

Which Double Glazing Company Is The Best? in Thornlie Western Australia

This may lead you to change on lights, which will result in greater energy expenses. Conduction is how readily a material performs heat. This is called the U worth. The U value for windows (revealed as Uw), explains the conduction of the whole window (glass and frame together). The lower the U worth, the greater a window's resistance to heat circulation and the much better its insulating value.

For instance, 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 chillier outside compared with inside, the heat loss through the windows would be: 6. 2 15 70 = 6510W That is equivalent to the total heat output of a large space gas heater or a 6.

How Does Double Glazing Keep Heat Out? in Craigie WA

Does Double Glazing Keep Heat Out in Calista Western Australia

If you select 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 readily 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 home 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 maximum possible solar heat gain. The SHGC declared by glazing manufacturers is always computed as having a 0 angle of occurrence. As the angle increases, more solar radiation is reflected, and less is transferred.
