The average UK home can save:
850 kg of CO2 each year with triple-glazed windows.
380 kg of CO2 each year with double-glazed windows.
If you upgrade from double to triple-glazed windows, you can save an extra 470 kg of CO2 a year. That’s about the same as driving a car for 1,175 miles, or driving all the way from York to Barcelona, Spain!

How do triple-glazed windows increase energy efficiency?
Triple-glazed windows have three layers of glass with two insulating gaps between them. These gaps are filled with air or gas, which helps keep the heat inside during winter and outside during summer.
This extra layer helps keep your home at a comfortable temperature, so you don’t need to use your heating as much. This means lower energy bills and a cosier, more efficient home.
Approximate cost saving:
How much you can save will depend on:
The size of your home.
The windows you are replacing.
Your gas and electricity prices.
When compared with single or double-glazed windows, you can save up to 50% on your energy bills.
For example, a four-bedroom, detached home can save £175 per year on its heating bills.

How do triple-glazed windows work?
Triple-glazed windows work exactly the same as double-glazed windows but with an extra layer.
They are made up of three layers of glass with two gaps in between. These gaps are filled with air or gas, making it even harder for heat to escape. This means you can use less energy to heat your home, lowering your bills.
Triple-glazed windows can also offer extra protection against outside noise, helping you enjoy a quieter and more peaceful home.
What do triple-glazed windows look like and where does it fit in your house:
Triple-glazed windows look like regular windows, but they have three sheets of glass instead of one. There are two small gaps between the layers of glass, usually about 16mm wide. These gaps are filled with air or gas to help keep your home even warmer.
Triple-glazed windows usually fit right into the same spots as your current windows. You can install them throughout your house. They work just like double-glazed windows, but they’re even better at keeping the heat inside and saving energy.
