Our team has compiled an ultimate guide for everything you need to know about triple glazing.

Triple glazing has excellent energy-efficiency compared to other glazing systems, helping you to save money on your energy bills. 

Noise reduction

You would think that the more panes of glass your window has, the better the noise reduction would be, right? Well, this isn’t exactly the case. The thickness of the panes of glass is more important. 

If noise reduction is a priority for you, with triple glazing you are able to choose the thickness of the panes of glass for the best noise reduction. 

The space between the glass panes also has an effect on how well your window reduces noise pollution. The bigger the space between the panes the more gas that can occupy the space resulting in better noise reduction.

There are many factors that can affect the lifespan of your triple glazed windows. These include things like how well they are maintained and the material used. 

That being said, window manufactures usually give triple glazing a lifespan of around 20 years.
