Replacing your single glazing with slim double glazed units

One of the most classic and iconic features on a traditional property is the sash windows, striking and evocative but not always the easiest to manage and with single glazing and the weights and pulleys; they are often draughty and not very thermally efficient.

Now, Chameleon can bring you a revolutionary double glazing system for the sash windows on your Chelmsford home without altering or changing this beautiful feature.

Retrofitted Into Existing Timber Frames

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 historic sash window, this double glazing can create insulation for the sash windows on your period Chelmsford property with less noise, draughts and lower energy bills.

Testimonials from satisfied customers

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

Any repairs for soft or rotten wood sections are undertaken using Accoya and Tricoya wood which has a profile far outstripping traditional hard and soft woods with superior weather resistance and longevity.

Sash windows draught-proofing Chelmsford

Draught proofing the sash windows on your Chelmsford home with Fineo glass will allow you to benefit from the lower heating bills and ambient room temperatures associated with a much newer property.

Chameleon double glazing can reduce heat loss by around half, more if you combine new double glazing with curtains or blinds. Enjoy a draught free home and improve your Energy Rating Certificate at the same time, contact Chameleon to find out more.
