Cavity Wall Insulation

About 35% of all heat loss from UK homes is due to un-insulated external walls.

 

If your home was built after the 1930s, the chances are that its external walls are made of two ‘skins’ with a small gap between them. This means they are ‘cavity walls’ and the gap between them can be filled with insulating material to stop the warmth escaping to the outside.

​

A cavity wall can be filled with an insulating material by injecting beads into the wall. This restricts any warmth passing through the wall, reducing the money you spend on heating.

​

You can check your wall type by looking at your brick pattern.

 

If the bricks have an even pattern and are laid lengthways, then the wall is likely to have a cavity.

 

If some of the bricks are laid with the square end facing, the wall is likely to be solid. If the wall is stone, it is likely to be solid.

​

If your home was built within the last 25 years it is likely to been already insulated or possibly partially insulated. The surveyor can check this with a borescope inspection.

 

Bill savings and things to be aware of:

​

• Can save between £145-£480 a year on your fuel bills depending on property size (Figures from the Energy Saving Trust and assume property is a gas heated home and sized between a flat to a detached home).

• Walls are normally drilled and then filled from the outside, which minimises disruption and mess.

• Can be completed in a few hours.

• Grant funding is available that can cover the full cost of installation (qualifying criteria apply).
