The primary role of energy efficient windows is to prevent air loss from inside the home. This in-turn means energy heating bills are reduced and the interior feels a lot more comfortable, especially during the colder months of the year. There are a few different kinds of insulated windows which will be suitable for a variety of locations and settings. Add to this fact, the technology is improving quickly and new window insulation types are emerging yearly.
A basic format of the typical energy efficient window is the double glaze design. This acts in the same way two layers of clothing do by maintaining temperature, usually heat. However, with double window panes, both warm and cold air is contained which is beneficial for all seasons. Triple window panes provide the same benefits and work in exactly the same way but with additional efficiency.
There is more to insulated windows than just the panes of glass. Gas can be added in-between the panes which provides a great deal more insulation that would be found otherwise. Such gasses include argon and the rather Superman-esque sounding krypton.
Energy efficient windows can also be purchased with special coatings which improve the efficiency of the glass. These are often referred to as low-emission coatings. Infra red light which is a primary source of heat, is reflected thereby aiding the retention of heat in the interior. In the warmer months this also has the effect of preventing the home from overheating by keeping the heat outside.
Another benefit of low-emission coatings is the prevention of ultraviolet light doing damage to fabrics and upholstery in the home. Whilst it won’t stop it entirely, the coating can reduce the fading of materials that are hit by sunlight on a daily basis, such as an expensive sofa or curtains. One can even find tinted windows that will reduce energy costs even more.
The final element which is often overlooked when buying energy efficient windows is the material of the frame. In most cases, insulated windows will come with either fiber glass or vinyl frames but for a more aesthetic look, wood composites can also do the job just as well and are widely available.
