Benefits of Double Glazing
Benefits of Double Glazing
Is your heat going out of the window?
Did you know that a fifth of your home's heat is lost through the windows? It's no wonder British homes have as much of an impact on the climate as all the fuel-burning cars, buses and other vehicles we use. Double glazing your home could cut your CO2 emissions by 740kg a year - that's over 7 times as much CO2 as switching to the best green electricity tariff - and save you a tidy sum on bills.
It could even give you some peace from noisy neighbours.
How does it work?
Around two million windows are installed every year in the UK
- The average household could save around 1.5 tonnes of CO2 a year by making their home energy efficient.
- The gap between the two panes in standard double glazing is 16mm whilst the optimum gap to significantly reduce noise levels is 100mm
Double glazing sandwiches a thin insulating layer of air, or an inert gas such as argon, between two panes of glass. That insulating layer is sealed in and helps prevent heat transfer. In other words, it keeps cold air out and a lot more of your hot air in.
It's more effective than secondary glazing, which simply inserts a second layer of glass inside the existing frame rather than coming as a complete sealed unit.
How will it make a difference?
A single-glazed window can lose as much as 14 times as much heat as the same area of well-insulated wall. No, no one's suggesting you brick up your windows, but consider the gains from double-glazing them:
- Double glazing halves heat loss through windows
- It reduces your heating bills by about £90 a year - enough to fund a return train trip to Paris once a year
- If everyone in the UK who needed double glazing fitted it, we'd save nearly five million tonnes of CO2.
