Double Pane Windows
Double Pane Windows Installation, Repair and Replacement
A double pane window, also known as an Insulated Glass Unit or IGU, is a window with two panes of glass separated by a vacuum or gas (like argon). Twice as efficient as a single pane window, IGUs are designed to reduce both energy loss and outside noise like street traffic, keeping warm air indoors during heavy winters, cool air in during humid summers and quieter all year long.
The Science Behind Modern Units
Even though double pane windows are more expensive, given the choice, most homeowners who can opt to install double pane windows or IGUs, which keep your home insulated during the harsh summer and winter months. Single pane windows do not have air pockets; heat passes through glass more readily than air. The air pockets in an IGU reduce the windows conductivity resulting in a better-insulated home. The twin panes are held in place with a spacer made of moisture-absorbent material called desiccant and the entire unit is sealed to prevent the inner air chamber from escaping. To further improve the insulating properties of the window, Glass Doctor offers IGUs with argon or krypton gas in the air space and Low-E glass.
