Cavity Wall Insulation

6 million homes in Britain have now had cavity wall insulation installed, and it's easy to see why - it's the smart way to save money. The Government regards cavity wall insulation as one of the most effective energy savings measures that most people can carry out on their homes and apart from saving money it's a major contributor to reducing emissions of carbon dioxide, the main greenhouse gas.

What are the benefits of cavity wall insulation?

By far the most heat lost from your home escapes via the walls as much as a third, so this is where its most important to insulate. Just this measure alone could cut your heating costs by up to 35%. By saving energy, your household will cause less CO2 to be produced. Studies suggest that every square metre of Cavity Wall Insulation will save more than a tonne of Carbon Dioxide over the average life of the building. For a semi detached house with an external wall area of 80m2, this equates to savings of 80 tonnes or more.

What is cavity wall insulation?

Most homes built since the 1920s have two layers of bricks with an air gap between them. Cavity wall insulation involves filling the gap between the inner and outer skins of brick with an insulating material which reduces the amount of heat that is lost through the walls.

What materials are used?

We use one of two methods to insulate your cavity walls:
  1. EcoBead is a high performance, injected, blown bead EPS insulation system
  2. Cosytherm Whitewool cavity wall insulation is a mineral wool system which is blown into an external wall cavity

There is no risk of penetrating damp due to bridging the cavity and the insulation materials are odour free. There is no risk to you or your home and materials and workmanship are covered by a 25-year CIGA guarantee.


Is cavity wall insulation easy to install?

The insulation is injected through small holes drilled in the exterior brickwork. We also install core vents in the outside walls if necessary. The whole process takes less than half a day and we take great care to preserve the appearance of your property.

Is my home suitable for cavity wall insulation?

Your home is likely to be suitable for cavity wall insulation if:
  • Its external walls are unfilled cavity walls
  • The masonry/brick work of your property is in good condition
  • The cavity is at least 50mm wide

How can I tell if I have cavity walls?

Most houses built after 1930 have cavity walls. You can usually spot cavity walls from their depth (walls more than 260mm thick are probably cavity walls) and by the pattern of the bricks. If the bricks are all ‘side-on’, with their long sides showing, there is probably a cavity. (If the pattern is mixed, with some bricks showing the shorter end-piece, they are probably solid, but do remember that solid walls can also be insulated.).
