Double glazed windows consist of two panes of glass that are separated by a gap that is only several millimeters thick. Air is trapped in this small gap, which in turn acts as an insulator that reduces the flow of heat through the windows. Some windows use argon as an insulating agent, since its higher density allows even less heat to escape than air. A drying agent is usually added in this gap in order to prevent moisture from forming inside the finished product. Double glazing not only reduces heat loss, but also cuts down on the level of noise that comes from outside.
Homeowners who install double glazed windows can expect to see a 10% to 12% reduction in heating costs, since the amount of heat that is normally lost through windows is dramatically cut down. This can help many households tremendously, since the average home equipped with single pane windows see a 60% heat loss. Double glazing can also cut down on noise pollution, as well as internal condensation.
The gap between the glazed windows must remain airtight and free of moisture in order for the insulation properties to remain intact. The development of condensation signifies the failure of the airtight gap. Since double glazed windows cannot be repaired like conventional single pane windows, the entire unit must be replaced with a new one.
