Retrofitting your single glazing with double glazed units and draught-proofing your timber sash windows

Improved energy




Replacing your single glazing with slim double glazed units

Sash windows and double glazing don’t seem to go together but it is possible to enjoy the benefits of double glazing with a new type of glass which can be fitted to the sash windows of your Watford home. 

A warmer, draught-free environment doesn’t have to be the exclusive province of modern houses as there are materials available which can provide 21st-century comfort without any compromise on your sash windows, one of the finest features on any period property.

Double Glazing Existing Periodic Sash and Casement Windows

Sash Windows Draught Proofing

Retrofitted Into Existing Timber Frames

Chameleon brings you Fineo glass, an incredibly thin glass with exceptional thermal regulation properties and, at just 6.75mm thick, perfectly proportioned to fit into the narrow rebate of an old sash window.  This glass is also lightweight so it won’t interfere with the delicate balance of the system of weights and pulleys.  Enjoy the comfort of double glazing for the sash windows of your period home in Watford plus all the financial and environmental benefits.

We are an official FINEO glass installer

Using Fineo glass which has unique thermal properties at a fraction of the width of standard double glazed units, you can eliminate noise and draughts and keep a warmer ambient temperature in your home.  Perfectly proportioned for the narrow rebate of a sash window, this double glazing can create insulation for the sash windows on your period Watford property with less noise, draughts and lower energy bills.

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

If your windows need any sash windows repairs then Chameleon uses Accoya wood uniquely resistant to weathering and rot to ensure your sash windows look beautiful year in year out.  Find out more about Fineo glass and Accoya wood from Chameleon and refurbish your sash windows without compromising on style.
