Home Cavity Wall – Do I have One? Eco Spray Foam

Home cavity walls are a common form of brickwork for residential and commercial properties, especially for the former. Typically, homes have two standard types of wall, the first being a solid wall, formed of pure brickwork and nothing else. Secondly, residential homes, especially post-1920, have been created with cavity wall layouts. A cavity wall is a type of wall that has a hollow centre, imagine two walls sandwiched together with a filling in the middle, this filling is the insulation. However, there are a significant amount of homes across the United Kingdom that have cavity walls without insulation, this can lead to a lot of energy wastage, colder homes and damaging effects on the house’s foundations. Insulating a cavity wall begins at first acknowledging if you have one, and then understanding why it is best to have it professionally insulated.

Signs You Have a Cavity Wall

It is a simple process to assess whether or not your property contains cavity walls or not. Follow the few steps below to find the answers you are looking for:

  1. 1920 – If your home was built post-1920, then there is a good chance that your house already has cavity walls structured in, it has been a common home design post-world war 1 for houses to be built with cavity walls in place.
  2. Pattern – You can simply assess your own brickwork to see if it has a certain pattern, depending on the pattern, you can tell if it is a solid wall or a cavity wall. Typically, if walls have an even layout pattern, it is more likely to be a cavity wall.
  3. Thickness – Another simple technique to assess your walls is to check the thickness. Walls that are greater than 260mm (26cm) thick are more likely to be a cavity wall, where walls that are thinner are more likely to be a solid wall.
  4. Length – The lengths of brick, similar to the pattern, also can indicate whether or not you have a cavity wall. If the lengths are similar across the wall then it is usually a sign that your wall does have a cavity.
