Cavity wall insulation

Cavity wall insulation acts as a blanket to help stop heat escaping through the walls of your home. Insulating your home isn’t a one off saving either, it will keep your home warmer in the winter and cooler in the summer, helping you to save money on your energy bills year after year.

It’s simple to install and usually takes less than a day.[2] Cavity Wall Insulation is a filling blown into the gap between your exterior wall, so there’s little fuss or mess.

Is my home suitable?

  • If your property was built between 1932 and 1982 then you are likely to have cavity walls.
  • If the thickness of your wall is greater than 11 inches then the likelihood of the property having a cavity is high.
  • If the configuration of the bricks in your house looks like the 'typical cavity walls' diagram then your house is more than likely to have cavity walls.
