Energy Saving Windows
Modern windows use special materials to treat the window glass. Low emission coatings are applied to the inside surfaces which reduce heat loss through the glass. The windows are constructed of two layers of glass with an inert gas between them. This gas – usually argon – reduces heat losses even more.
To prevent the sun from over-heating the sun during the summer, the glass can be treated with a reflective coating that reduces interior temperatures. This type of coating, however, is not suitable for cold climates because the windows can also be a source of winter heat during sunny days.
There are many components to energy saving windows that can help cut down on your heating and cooling costs. The glazing’s (layer of glass) can be coated, and some manufacturers may use multiple glazing to reduce heat loss.
Coated glazings are beneficial in reducing heat loss and they can reduce the amount of Ultra Violet (UV) light that enters the house. UV causes colors to fade in drapes and carpets, so using this type of window cans make these items last longer.
The frames of energy saving windows can be made from wood, aluminum, PVC, or composites. The best types are wood or PVC because the heat loss from the frame itself is reduced. To further enhance the energy saving qualities of the windows, non-metallic spacers are used between the glazings.
Windows are sometimes graded according to their insulating value. Investing in energy saving windows is a great idea for both new and older homes. The windows cost a bit more than conventional windows but the savings in your utility bills will make up the difference in a few years.
