Cavity Wall Insulation Types Explained!

Cavity walls have been a fixture in many UK homes ever since they were introduced in the late 1920s. These cavities can provide a certain amount of sound and heat insulation; but, these alone are not enough to keep homes well insulated. Fortunately, there are cavity wall insulation types that can help reduce heating bills as well as carbon emissions in the home. So, you may be asking: should I get cavity wall insulation for my home? What are the cavity wall insulation types out there? Can I get funding through successful cavity wall claims? Here is our guide to insulating your cavity walls.

Cavity Wall Insulation Types

There are two main cavity wall insulation types on the market: foam and polystyrene bead. Foam cavity wall insulation is pumped into the cavity through small holes drilled in the outer cavity. This is a good option for properties using engineered bricks. The other option, polystyrene bead insulation, is pumped in through holes in the outer wall and mixed with adhesive. Once the beads settle they bond with the adhesive to form an insulated barrier. In either case the insulators must do a professional job and they need to inspect the cavity first for any issues such as damp.

Should I Get Cavity Wall Insulation?

Before you decide to apply for cavity wall insulation you should consider the following questions:

  1. When was your house built? Houses built after 1982 will have cavity wall insulation, whereas houses built earlier are less likely to have insulation.
  2. Is your wall a cavity wall? A cavity wall will feature a stretcher bond on the external wall, whereas a solid wall will have an English or Flemish bonding pattern.
  3. Are the cavity walls exposed to the weather? If rain or water penetrates the cavity it can make insulation ineffective. Make sure you damp proof the wall before putting in insulation.
  4. Are the external walls in good condition? Check to see there is no damage to any of the external walls so they will be able to keep moisture out.

Once you have determined that your cavity wall is secure and in need of insulation you can start looking at the best way to fill it.
