Cavity Wall Insulation Installers of your home will reduce energy bills by keeping heat in, and reducing drafts. It also reduces carbon emissions (which is good for the environment) as it keeps more of the heat generated in your property inside.
It also offers enhanced soundproofing. The material used in cavity wall insulation is able to absorb and limit the transmission of noise. This is particularly beneficial if you live near busy roads or in an area with high traffic.
Generally, most homes are suitable for cavity wall insulation as long as they have the required brick pattern and
are free of any defects. A surveyor should check your property for suitability before the work starts. Often, the surveyor will use a borescope to check the condition of your walls and the depth of your cavity. This will also let them know which type of insulation is suitable for your house.
A qualified registered installer will drill small holes in your external walls and then pump the insulating material into the cavities. It is usually made from a mineral wool or polystyrene granules (also known as beads).
This process should only take around two hours for the average house with easily accessible walls and should not make any mess. A reputable insulation professional should be a member of a recognised body such as the National Insulation Association or CIGA. This ensures they will comply with building regulations and will have a 25 year guarantee.
