All properties lose heat through their windows. But energy-efficient glazing keeps your home warmer and quieter as well as reducing your energy bills. That might mean double or triple glazing, secondary glazing, or just heavier curtains

The benefits of energy-efficient windows

  • Smaller energy bills: replacing all single-glazed windows with B-rated double glazing could save you around £165 per year on your energy bills.
  • A smaller carbon footprint: by using less fuel, you’ll generate less of the carbon dioxide that leads to global warming - typically, 680kg a year.
  • A 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 outside noise.
  • Reduced condensation: energy-efficient glazing reduces condensation build-up on the inside of windows.

The costs and savings for energy-efficient glazing will be different for each home and each window, depending on the size, material and installer. Double glazing should last for 20 years or more.

How energy-efficient glazing works

Double-glazed windows have two sheets of glass with a gap between them, 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 and Energy Saving Trust Recommended logo.

Energy-efficient windows come in a range of frame materials and styles. They also vary, depending on:

  • 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.
