South West Cavity Wall Insulation

Why should I use cavity insulation in my home?

Cavity wall insulation can be quickly installed with very little fuss and there are many benefits.

How does cavity wall insulation work?

To start we need to find out if your home is suitable for cavity wall insulation. To assess this we drill small holes in your outside walls. If it's suitable for your property, the cavity between the inner and outer walls is then filled with insulating material. The holes in the brickwork are then filled in again.
The installation process takes just a few hours and should come with a Cavity Insulation Guarantee Agency (CIGA) guarantee.
