Cavity Wall Insulation Installers
Most homes built after the 1920s have cavity walls – brick ‘skins’ with a gap between them – that can be filled with insulation to make your home more energy efficient. This is one of the cheapest ways to improve your home’s efficiency and could save you up to PS160 a year in heating bills.
Cavity wall insulation installers fill the space between your house’s outer brick walls by drilling a series of small holes, usually at 1m intervals around the outside of your property, then injecting in the insulation material. A reputable company will be able to provide a choice of materials including mineral wool or polystyrene beads, although spray foam insulation can also be used. The best installers will be able to advise you on the best option for your home.
The Benefits of Cavity Wall Insulation: Why You Need It
Whichever insulation is chosen, it will be injected through the holes in your external wall and then sealed with cement. The installer will also inspect the brickwork to ensure there are no damp patches that need addressing before proceeding, as moisture or dampness can affect the performance of the insulating material.
It is important to choose a reputable and experienced contractor for your cavity wall insulation installation as incorrectly installed insulation can lead to problems, some of which may not be immediately obvious but others that could cause structural damage to your home. A good installer will be registered with the Cavity Insulation Guarantee Agency and offer a 25-year industry backed warranty, ensuring you can have peace of mind that your insulation is installed correctly.
