It is usually recommended that you install double glazed windows if it is a new building or if you are replacing your existing windows altogether.

These consist of two panes of glass that have air trapped in between them. The air space is generally three-quarters of an inch thick and this air acts as an insulator.

The added insulation means that your house is protected against heat loss.
