Modern windows use special materials to treat the window glass. Low emission
coatings are applied to the inside surface which reduce heat loss through the
glass. The windows are constructed of two layers of glass with an inert gas in
between them. This gas – usually argon – reduces heat loss 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 glazings (layers of glass) can be coated,
and some manufacturers may use multiple glazings to reduce heat loss.
Coated glazings are beneficial in reducing heat loss and they can also 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 can 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.
