Double-glazed windows are constructed from a frame and a glazed unit featuring an insulating layer of Argon gas sandwiched between two panes of glass. A double glazed unit can be made with different types of glass to create windows that are specific to different needs, but the primary benefit of double glazing is thermal insulation – to keep in the heat and stop the cold air entering from outside to make the room more energy-efficient.
