What Is Cavity Wall Insulation?

In most houses built after 1924, the external walls of the building are made of two layers with a small cavity between them (an air pocket). If your home has unfilled cavity walls this can lose a great amount of heat energy and a portion of your heating bills will be spent warming the air outside.

How Cavity Wall Insulation Works

Without cavity wall insulation you can lose up to 35% of heat through the walls of your home.

Filling the gap between the two walls of a house with an insulating material massively decreases the amount of heat which escapes through the walls of your home. It will help create a more even temperature in your home, help prevent condensation on the walls and ceilings keeping it cooler in the summer and hotter in the winter.
