Advantages of PVCu windows
All properties lose heat through their windows. But energy-efficient glazing keeps your home warmer and quieter as well as reducing your energy bills.
How energy-efficient glazing works
Double-glazed windows have two sheets of glass with a gap between them, to create an insulating barrier that keeps heat in. This is sometimes filled with gas. Triple-glazed windows have three sheets of glass, but aren't always better than double-glazed windows.
Energy-efficient windows must also deal with:
- how well they stop heat from passing through the window
- how much sunlight travels through the glass
- how little air can leak in or out around the window
