Improving the energy efficiency of your windows can make your property quieter, warmer, and reduce your energy costs.
Double 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.
Below is a table showing how much money you could save on your energy bills by installing double glazing:
| Energy rating | Detached | Semi-detached | Mid terrace | Bungalow | Flat |
|---|---|---|---|---|---|
| A++ rated | £110 - £115 | £80 | £60 | £60 | £35 |
| A+ rated | £105 | £75 | £55 | £55 | £30 - £35 |
| A rated | £100 - £105 | £65 - £70 | £50 | £50 | £30 |
| B rated | £95 - £100 | £65 - £70 | £50 | £50 | £30 |
| C rated | £95 | £65-70 | £50 | £50 | £30 |
