Sash windows double glazing in Bishop’s Stortford

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 are without doubt one of the most celebrated aspects of a character property but they are well known for rattling in the wind, letting the draughts in and the heat out.  If you love the sash windows on your Bishop’s Stortford home but would also like to feel a little warmer then there are double glazing options available which won’t require you to alter or remove these fine windows.

We bring historic wooden windows back to their former glory and make them energy efficient

Retrofitted Into Existing Timber Frames

Fineo glass is a very narrow but super thermally efficient slim  vacuum sealed double glazing  with a thickness of only 6.7mm and thermal efficiency of a standard triple glazing, perfect for the narrow rebate of old sash windows. Fineo will cut out draughts and noise, lower your heating bills and reduce your carbon footprint all in one sheet of glass which you can’t even tell is double glazing.  Fineo glass can be retrofitted into existing timber frames. Now you can have all the advantages of triple glazing for the sash windows on your Bishop’s Stortford home without having to compromise on window design. As an official Fineo installer, Chameleon would be delighted to discuss your double glazing needs.

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 Bishop’s Stortford property with less noise, draughts and lower energy bills.

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

For windows that also need a little care and repair, we use Accoya wood to replace soft and rotten sections of timber.  Accoya is a new timber which has been manufactured to withstand weathering and moisture and is far superior to the more standard hard and soft woods which are used for window repair.
