Cavity Wall Insulation
HOW IT WORKS... Our Deluxe Cavity Wall Insulation produces a seamless insulating layer with no joins or gaps, which reduces energy loss and makes for a more comfortable home. If you have a house that was built after the 1920s, then you will probably have cavity walls - a wall made up of two layers with a gap, or cavity, in between. If no insulation has been built into this space, then you can expect around a third of your heat to escape through the walls.
