Improving the energy efficiency of your windows, making your property quieter, warmer and potential saves you £120 a year*.
Energy efficient window glazing
Double-glazed windows have two sheets of glass with a gap in between, creating an insulating barrier to keep heat in. Triple-glazed windows have three sheets of glass but aren’t always better than double-glazed windows. To choose the most energy-efficient window, select the one with the best 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.
