What is a cavity wall?

Two brick-thin walls make up a cavity wall. These walls are also known as “leaves” or skins. Also known as a gap, a cavity is also referred to. They are held together with metal wall ties.

How do you determine if your walls contain cavities

Your home’s age is the first indicator. You can examine any brickwork to determine the age of your house. Bricks of the same size will be found in homes with cavity walls. You can measure the thickness of the outer walls by determining the thickness of brickwork that has been covered up. You can also inspect Windows and Doorways. Cavity walls are brick walls that have a thickness greater than 10 inches. However, solid stone walls can be extremely thick.

Professional installers should drill a small hole into the wall. This will let you know if the wall is insulated. This inspection is also known as a borescope.

To verify insulation, contact your local building control department.

These clues may also be helpful in avoiding borescope inspection.

When installing wall cavity insulation, the installer will drill holes of 1-inch at regular intervals.

Inspect your attic. It is possible that the cavity insulation material is seeping from your wall’s top. This could be a sign of a problem. To remove and seal the item, it is best to contact a professional.

There is no one area of steel- or timber-framed construction.

Timber-framed homes can often look identical to bricks even though they aren’t. These buildings can’t be cavity wall insulated because they require the cavity for moisture escape.

You can make cavity wall insulation from mineral fibre wool or polystyrene granules. They must all be made in accordance with British standards.

Mineral wool

Most commonly, mineral wool is used because of its softness. It works in the same way as mineral “quilt”, but is cut into smaller tufts so that it can be blown into walls. To retain its insulation properties, it must be kept dry. It can settle over time and cause air pockets at the walls’ top.

Granules & beads

Popular options include granules and beads. They trap heat well and are effective at creating insulation in walls. However, loose granules can sometimes escape through the airbricks.


Foam insulation is best for thermal cavity walls. Foam installation can be difficult and should only be left to professionals. Some foams can also become unstable with time.

Installers who aren’t trained could block airbricks and flues.

They could blow insulation materials off walls into your loft, next door, or ceiling.

Air pockets can be created if the material is not distributed evenly. This can cause condensation or mould to form in your walls.
