What is Cavity Wall Insulation?

Cavity wall insulation involves filling the gap (cavity) between the two layers of external walls with insulating material. Most houses built after the 1920s have cavity walls, consisting of an inner and outer wall separated by a small space. As a result, this cavity can be insulated to prevent heat loss and improve the energy efficiency of the home.

It works by trapping air within the insulating material, reducing the transfer of heat through the walls. Consequently, this helps maintain a stable indoor temperature, reducing the need for constant heating or cooling.
