Cavity Wall Insulation
Fitting cavity wall insulation is one of the most cost-effective ways to improve your home's energy efficiency and reduce your energy bills.
What is cavity wall insulation?
Most homes built in the past 100 years were built with two layers of wall, leaving a small space or 'cavity' between the two layers.
The purpose of the cavity is to help prevent rain water from penetrating through the outer wall to the inside of the property. However, unfilled cavities also let heat escape and could be responsible for 35% of all heat lost from your home.
How cavity wall insulation is installed
Cavity walls can be filled with insulation in just two hours
You’ll need a registered installer to fit cavity wall insulation – it's not a job you can do yourself.
Cavity walls are filled with an insulating material; commonly-used materials include mineral wool, polystyrene beads or foam. Insulating cavity walls will help trap heat and prevent warmth from escaping.
A registered installer will be able to check your property’s suitability for cavity wall insulation and recommend the best type. The insulation is blown into the wall cavity from the outside of your property through drilled holes. The holes are then filled in with materials that match your brickwork.
Cavity wall insulation normally takes around two hours to install, but this depends on the size of the house and other factors, such as ease of access.
Check whether your home is suitable for cavity wall insulation
If your home was built from 1920 onwards, it's likely to have cavity walls. The cavity should be at least 50mm wide and the walls need to be in good condition to be suitable for cavity wall insulation.
If your house was built in the past 10 years, it's likely that he cavity walls have already been insulated.
