Solid Wall Insulation

Solid Wall Insulation

If your home was built before the 1920s then it is likely to have solid walls. Therefore, the walls do not have cavities. They will usually be made of brick or stone. These properties were built before modern day building regulations and can be very cold and expensive to heat. You can normally tell if your home has a cavity or a solid wall you can usually tell if you look at the brickwork outside your home. If you can see full-length bricks with half-length bricks (or header bricks) around the middle of the wall this is a good sign that you have a solid wall. Another way to find out is to measure your wall from a door or window. If it is thinner than 30cm it is probably a solid wall. It is possible to insulate a solid wall with internal or external insulation.
