Easyfix Filmglaze - Thermal Film Insulation

Filmglaze is a simple secondary glazing system that uses special thermal film as an insulator instead of glass or plastic glazing sheet. The film provides a thermal seal by being attached to the window surround by double sided adhesive tape, after which gentle heat is applied to the film to take out wrinkles and provide a smooth tight finish that insulates the window.

Filmglaze is easy and quick to install, using a few household tools, and full instructions are supplied with each kit, or can be printed from the PDF on this page. It is possible to re-fix handles and other fittings through the film, which is also repairable if punctured.

Filmglaze is very affordable, as it does not require the extra cost of glazing sheet, it allows emergency access to the window, and the film itself can be re-used once it has been carefully cut out.

Each Filmglaze pack contains the thermal film, suitable double sided tape and Surface Preparation Wipes, that clean and degrease the window surround before installation.
