Old sash window double glazing Hitchin

Swap high heating bills and draughts for a constant, warm and draught-free home with the revolutionary new Fineo double glazing vacuum sealed glass.

At only 6.7mm thick, Fineo is perfectly proportioned for retrofitting this double glazing glass into the narrow rebates of old sash windows. With this service, you can upgrade your home and lower your heating bills and reduce outside noise without changing the appearance of one of the finest features of your house, this is especially important if you living in a Grade 2 listed property with old, inefficient wooden windows.

If you are thinking of replacing inefficient single glazing with double glazing, Fineo slim vacuum glazed glass makes it possible now.

This new type of vacuum glazing retrofitted into existing timber frames will bring historic windows into the 21st century without any alterations.

If your windows need any repair then we can replace soft or rotten sections with Accoya wood, uniquely weather-proof and rot-resistant. For sash window double glazing in Hitchin contact Chameleon, official Fineo glass installer and specialist in historic window renovators, today.

We don’t do sash inserts – we reuse your old sashes

We can make invisible adjustments to help the glass fit and because it is so light, it won’t disturb the delicate balance of the weights and pulleys. Install double glazing to the sash windows of your 

Hitchin property without altering or spoiling this classic architectural feature.
