Cavity Wall Insulation
Fill the gap in your walls to stop heat escaping.
What it is & how it works
Homes built with cavity walls have a gap between the inner and outer leaves that can be filled with insulating material to dramatically cut heat loss. Cavity Wall Insulation (CWI) is quick to install, non-disruptive and highly cost-effective — and is frequently delivered at no cost through GBIS and other government funding for eligible households.
