  • A double-glazed window consists of two panes of glass with air between them. A drying agent is added between the two panes of glass to ensure that no moisture can enter the space.

    How It Works

    The efficient windows collaborative reports that double-glazed windows cut heat loss in half when compared to traditional single-pane windows. This occurs due to the insulating effect of the layer of air in the double-glazed windows.

    Good For The Environment

    Much heat is lost through windows. When double-glazed windows are installed, heating bills are cut anywhere from 10 to 20 percent.

    Moisture Must Be Avoided

    If condensation appears between the two panes, the window cannot be repaired; it must be replaced.

    Home Security

    Double-glazed windows are harder to break than normal windows. Many home invasions occur through windows, so changing to double-glazed windows increases home security.

    Double-Glazing Film

    If a house is fitted with traditional single-pane windows, it is possible to inexpensively get the double-glazed effect by adding double-glazing film. The film is placed over the window and then stretch it flat by going over it with a hair dryer.
