Cavity wall insulation installers are one of the most effective ways to make your home more energy efficient and save money on heating bills. It stores heat within the inner walls and halts cold air from entering the house, helping to reduce energy costs by up to 35%. You may also be eligible for government-backed funding to help you with the cost of the installation.
To carry out the work, registered installers will drill small holes at intervals of about 1m in your property’s outer brick walls, and then blow insulating material, which is usually either mineral wool or expanded polystyrene beads, into the gaps using special equipment. The bricks are then filled in again so you won’t even notice the holes.
Choosing the Right Cavity Wall Insulation Installers: What to Look For
Before insulating your home, your installer will check that the external walls are suitable for cavity wall insulation. This will involve carrying out a survey and ensuring that your walls have unfilled cavities, are at least 50mm wide, and do not contain rubble. Your installer will also check that your masonry or brickwork is in good condition and that you don’t have damp problems that could be exacerbated by cavity wall insulation. If you live in a block of flats, your installer will need to get consent from everyone in the block to install insulation.
The energy savings gained from the improved thermal efficiency of your home should mean that the cost of the insulation is quickly recovered through reduced energy bills. You should also see a reduction in carbon emissions, which is a bonus for the environment!
