Cavity wall insulation
Up to 35% of the heat in your home is lost through the walls. Insulating your home can give you one of the biggest savings on your energy bills. Cavity wall insulation alone could save up to £145 per year.
What is a cavity wall?
Cavity walls are two layers of brick or concrete masonry with a hollow gap or cavity between them.
How is cavity wall insulation installed?
A hole measuring between 18mm and 25mm is made in the walls (from the outside) and insulation material is blown through the hole. The holes are filled in and, where possible, matched to the existing appearance of your external walls.
Is my home suitable for cavity wall insulation?
Only homes with cavity walls can benefit from cavity wall insulation. If your home was built after 1920 and / or the walls are thicker than 28cm, then it is likely to have cavity walls.
