Benefits of energy-efficient windows
Smaller energy bills.
Smaller carbon footprint.
More comfortable home: energy-efficient glazing reduces heat loss through windows and means fewer draughts and cold spots.
Peace and quiet: as well as keeping the heat in, energy efficient-windows insulate your home against external noise.
Reduced condensation: energy-efficient glazing reduces condensation build-up on the inside of windows.
How energy-efficient glazing works
Double-glazed windows have two sheets of glass with a gap in between, usually about 16mm, 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. To choose the most energy-efficient window look for the BFRC rating.
Energy-efficient windows come in a range of frame materials and styles. Performance criteria vary according to the following:
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.
