CAVITY WALL
INSULATION
With the cost of heating your home continuing to increase, Cavity Wall Insulation is one of the most effective methods to minimise energy waste and save you money. It’s estimated that up to 35% of heat in a property is lost through the walls which could be costing you £100’s each year.
WHAT IS CAVITY WALL INSULATION?
A cavity wall is made of two separate thin walls with a gap (or cavity) between them. They’re usually held together by metal wall ties. Cavity Wall Insulation is installed by filling air pockets between the walls in your home with insulation material designed to inhibit heat transfer.
Once inserted, the air between the walls can no longer move freely which reduces convection. To put it simply, heat can no longer escape your home and it takes less time to heat your spaces. As home improvement measures go, it’s non-invasive and causes very little disruption to the household.
All work is done from the outside of your external walls. An insulating material is injected into the wall through small holes drilled in the mortar joint of the wall. It can normally be done in two hours.
HOW IS IT FITTED?
Getting your cavity walls filled is perhaps the most straight forward and sensible way to to reduce noise through external walls, while also providing excellent insulation benefits

IS MY PROPERTY SUITABLE?
Your property must meet the following criteria before Cavity Wall Insulation can be installed:
- Your home has unfilled cavity walls made of brick
- The cavities are at least 2 inches wide
- The brickwork or masonry is in good condition
- Your external walls are accessible. If some are joined to a neighbouring house, we need to insert a cavity barrier
- Your home is less than 12 metres high
- Your internal walls are dry. Wet wall insulation is worse than no wall insulation, so if you have any damp patches, you’ll need to get the cause sorted out before installing insulation
- There are no areas of steel or timber-framed construction
