CAVITY WALL INSULATION
Around 35% of heat is lost through the external walls of your home. By installing cavity wall insulation, your home will warm up quicker and stay warmer longer and reduce those inevitable fuel bills by up to 25%. It also helps to inhibit mould growth that can form on cold external walls.
Most homes built after 1930 can benefit by having cavity wall insulation.
