What is Cavity wall?

Did you know that almost a third of heat lost in a home without insulation is through the outer wall?

A way to stop this from happening is to fill your cavity walls with insulation, which will retain heat for longer and lower your energy bills.

For houses built before 1990 and after 1920, you are likely to have unfilled cavity walls; filling them with insulation will keep the cold from coming into your house via the external walls.

Cavity wall insulation is typically made up of mineral wool which will be inserted into your internal walls using drill holes.

It is a easy to do and relatively mess-free insulation installation process and should take no more than a few hours!
