Replacing your single glazing with slim double glazed units

Sash windows are one of the most valued characteristics of period properties but they are also well-known for being temperamental and rather draughty. Now you can enjoy all the benefits offered by double glazing on your Bedford home in Bedfordshire with our transformative new slim vacuum sealed double glazing system designed specifically for sash windows.

Retrofitted Into Existing Timber Frames

The thermal insulation of Fineo glass will offer you a constant temperature with a draught-free environment which will simultaneously lower your energy bills and improve your energy rating. This glass can reduce heat loss by more than half and offers modern 21st-century comfort in a period setting. It can be retrofitted into existing period timber frames. As part of a double glazing project we also offer timber window refurbishment and painting.

Retrofitted Into Existing Timber Frames

We are an official FINEO glass installer

Chameleon is an official installer of a new glazing product called Fineo glass which is incredibly thermally efficient, equivalent to modern sealed unit triple glazing but which fits in a single pane to the narrow rebate of traditional sash windows. Appreciate all the advantages of double glazing for the sash windows on your Bedfordshirehome without having to replace this unique and beautiful period feature. Fineo glass is very light with a thickness of only 6.7mm so the delicate balance of your sash windows is not disturbed and the weights and pulleys will run as smoothly as ever. If the rebate needs to be widened slightly then we can do this without damaging the structural integrity or appearance of the original windows.

Testimonials from satisfied customers

As a part of the retrofitting process, we also repair windows’ timber frames

If your windows need a little care and repair then we can also replace soft or rotten sections with Accoya timber which can defy weathering and rot with exceptional longevity compared to more traditional woods.
