Chances are the external walls of your house are solid walls instead of cavity walls if it was constructed before the 1920s.  

For those who don’t know: 

  • Cavity walls are made of 2 layers with a cavity or tiny gap between them. 
  • Solid walls don’t have a gap. Thus, you can’t fill them with cavity wall insulation. 

However, you can still insulate solid walls, either from the outside or the inside. Keep in mind that it’s much more expensive compared to insulating a regular cavity wall. However, you’ll save a lot of money on your heating bills.

Know the Type of Wall 

Chances are your walls aren’t insulated if you’ve got solid walls. However, before that, you have to find out first what type of walls you’ve got.  

You can look at the bricks’ pattern if you can see the brickwork on the exterior side of your home. This can show how the wall has been constructed. 

  • Typically, the bricks would have the same pattern. In addition to that, every brick placed lengthways if the house has cavity walls. 
  • The bricks would have alternating patterns, with a couple of bricks placed throughout the wall if your house has solid walls.  

You can also tell what type of walls you have by measuring the wall’s width if the brickwork has been covered. Check the door or window on one of your external walls.  

  • A narrower wall is possibly a solid wall. Stone walls might be thicker. However, they’re typically solid. 
  • It is possibly a cavity wall if a brick wall is more than 250mm thick.
