What are double glazed windows? And why do they do?
Double glazing uses two panes of glass separated by a layer of argon gas to keep your home more energy efficient and reduce sound. The argon gas is a poor heat conductor and therefore keeps warm air from escaping, while the second pane of glass acts as a barrier to noise.
Double glazed windows are an ideal energy efficient choice with the added benefit of minimising noise. The sealed air gap between the two panes acts as an added layer of insulation. This added thermal resistance reduces the amount of heat escaping in winter and keeps your home at a more comfortable temperature. Double glazing has the reverse effect in summer, preventing unwanted heat from coming into the home. This extra insulation lessens your reliance on artificial heaters and air conditioners and can ultimately reduce your energy costs.
