What is a cavity wall?

Cavity walls are two layers of brick or concrete masonry with a hollow gap or cavity between them.

How is cavity wall insulation installed?

A hole measuring between 18mm and 25mm is made in the walls (from the outside) and insulation material is blown through the hole. The holes are filled in and, where possible, matched to the existing appearance of your external walls.
