Vacuum Glazing - Less Is More

Sash Window Preservation is a fully accredited double glazing company with an excellent reputation. One of the reasons for our reputation is bringing the very best products to our customers. A new product we are very excited about is Fineo glass. This vacuum insulating glass combines exceptional thermal insulation with extreme thinness, the glass has a thickness of 6.7mm and a U-value of just 0.7. It’s fantastic insulation helps your home to stay warmer for longer as it allows more heat to enter your rooms than other glazing. It also has the added advantage of reducing your dependency on fossil fuels to heat your home.


With Fineo glass we can preserve your existing timber windows when fitting the glass, maintaining your home's unique characteristics and providing a sustainable solution for your new windows.
