How Cavity Wall Insulation Works

Alpha Insulation Icon

What it is

Cavity walls are built with a gap (or cavity) between the inner and outer layers of brickwork.

The problem

This cavity allows heat to escape, which can lead to higher energy use and colder rooms.

The solution

Cavity wall insulation fills the gap with insulating material such as bonded beads or foam.
