Cavity Wall Insulation

If your home was built after 1920, its external walls will probably be made of 2 layers of brick or block with a gap or cavity between them. With uninsulated cavity walls, around one third of the heat escapes meaning that more fuel is required to keep it at a comfortable temperature. In a typical 3 bedroom semi-detached house with gas central heating, you can save up to around £140 a year on your heating bills by insulating your cavity walls.*

6 million homes in Britain now have cavity wall insulation. The Government regards it as the most cost effective energy saving measure that most people can carry out on their homes.
