Double glazed windows are a popular choice for insulating a home or business’s interior from the outside. Insulating glass is comprised of two or more windows framed by a plastic vacuum or gas filled cavity to prevent heat transfer through a particular portion of the structure envelope. These windows are framed with special aluminum, rubber or polycarbonate materials which each have a specific thermal value, as well as an energy efficiency rating. Because these windows are airtight, they prevent air leaks from entering the building and consequently lowering the inside temperature of the space. A window that operates only half of its effective level will reduce air infiltration and improve the inside temperature of the structure envelope by allowing fresh air in while maintaining the heat and humidity levels inside.
The traditional method of installing windows is to frame the openings with standard glass and then add a second sheet of glass to make a sealed compartment. This second glass acts as a barrier, keeping the interior air from penetrating through the spaces created by the original glass. One disadvantage of using this method was that drafts could be severe in certain areas of the room due to the formation of a partial seal around some of the glass panes. Also, the operation of double-glazed windows required additional equipment such as gas regulators to keep the air inside the room constant. Modern double glazed windows to eliminate these problems by incorporating an airtight seal around the perimeter of the window pane, and by using two panes of glass, the operation is virtually continuous.
An alternative to single-glazed windows is a double-gas filled insulating layer. This layer can be made of any gas, but most commonly it is formed from argon. Although it may sound like it would increase the cost of insulating glass, there are many companies today who provide these services at competitive prices. Due to the fact that argon gas is a lower density, less expensive gas than other gases, the total cost of installing double glazed windows is still low. This is also advantageous because argon’s effectiveness at insulating heat is much better than that of CO2.
The best way to insulate a space, without having to use any extra energy, is to have double glazed windows. These windows will allow the warm air from inside to be trapped, which will prevent the outside air from entering while keeping the inside temperatures constant. In the summer the heat coming into the room is kept constant by the heat created by the glazing. In the winter, the same heat is allowed to enter, but the insulating properties of the panes are interrupted. As a result, the room becomes cold in the winter but becomes hot in the summer. This is because the panes stop allowing heat to pass through them.
Another benefit to double glazed windows is that they help prevent heat loss. Heat is one of the biggest reasons why homes fail to keep their temperature balanced. Windows and doors can allow considerable amounts of heat to escape while locking in cold air inside. Panes of glass, rather than solid shutters or blinds, are the perfect solution to this problem. A thick glass pane with a tight seal is an effective barrier to heat loss.
There are many different types of double glazed windows, but all use an insulating material that stops heat loss. The two most common types are double hung and single hung. The most efficient of these is a double hung window. These windows consist of two panes of glass, with a thin space between the panes.
A double-glazed window with a double glazing membrane is less efficient than a single pane window in terms of sound reduction. Since the noise from passing windows is very loud, a space is needed between the panes. In this case, the insulating material is made up of several small windows that open inwards and compact into one large pane. This means that any sound that might be made by passing windows is muffled by the larger opening.
Double glazed windows also have a positive environmental impact. Not only are they more energy efficient than traditional methods, but they have the potential to save millions of kilowatts of electricity over the course of their lifetime. When combined with proper insulation, glazing reduces the amount of heat lost through the home as well. For these reasons as well as their energy efficiency, timber windows make an excellent choice for new construction and renovation.
