In this month’s news piece we explain what double glazing is, how it works, the advantages of having it installed in your home and what types of double glazing are available.
What is double glazing? Double-glazed windows consist of two panes of glass with a layer of air or gas between them. In contrast, single-glazed windows have only one pane and no gap. How does it work? Double glazing works as an insulator in much the same way as a cavity wall. Having two panes of glass doubles the amount of glass that heat has to get through but the main insulating power is from the air gap. It is a poor conductor of heat and therefore keeps warm air trapped inside your home.
