Cavity wall insulation instantly creates a warmer environment in your home by reducing the amount of heat which can escape through your walls.
More heat is lost through the walls than any other part of your home. This means that instead of paying to heat you home, up to 40% of this heat is being transferred through the walls and onto the street. However, free cavity wall insulation grants in 2014 are available and can make this energy saving improvement less costly to implement. Grant funding is also available for a free boiler to be installed in eligible households.
How is cavity wall insulation installed?
A professional installer will take around 2-3 hours to insulate the walls of an average sized 2-3 bedroom house. There will be a minimal amount of disruption and the installer will clean up any mess that may have resulted from the installation.
A series of small holes of approximately 25mm will be drilled into the wall of your property in order to reach the cavity. Insulation material will then be blown into this cavity, consisting of tiny pockets of air which prevent cooler air from passing through.
Is my property suitable?
If you can see small drill holes on your outside walls, you may already have cavity wall insulation.
As obvious as it may sound, a property with solid walls cannot have this type of insulation installed. If your property was built between 1925 and 1990, there is a high probability that it was constructed with cavity walls. Many houses built before this will have solid walls, and houses built after 2005 will have been subjected to planning regulations which required insulation to be installed during construction.
What are the benefits of cavity wall insulation?
There are many advantages to installing wall insulation. Here are just some of them:
