There is a growing interest in triple-glazed windows to insulate homes and lower energy bills.

Double glazing has a U rating of around 1.2, while triple glazing can provide a rating as low as 0.5. This means it increases the insulation for your home and saves energy use over time.

If you have many windows, this adds significant extra cost, and it may take years before you see the payback on your energy consumption. However, with more pressure on homeowners to improve energy efficiency, triple-glazed windows could add value to your home.
