If you have a listed property and wish to retain the original sashes and glass in your windows, then secondary glazing could be a cost-effective option for you to consider.

Secondary glazing is a fully independent window system installed to the existing windows, on the inside of the property. It’s usually constructed with a lightweight and thin aluminium frame, so it won’t block the sunlight or obstruct your view.

Slender, discreet and efficient, it’s perfectly suited to homes in conservation areas and Grade II listed buildings.

We offer secondary glazing to suit every application, including openable, removable and fixed units.
