What Are Solid Walls?

A solid wall is constructed as a single series of bricks or stones that have no cavity. These walls are usually 9 inch solid walls but there can be granite or stone walls which are up to 16 inch depth.

An average cavity wall is usually around 12 inches or so.– and therefore no room for insulation inside the wall.

If your, it probably has external solid walls, and may also have internal solid walls.


What is solid wall insulation?


Solid wall insulation is purely attaching a layer of insulating material to either side of a solid wall, to prevent heat loss

This insulation is available for installing inside or outside your home and does the same thing whichever route you choose.

The idea is to lower the U value of your walls, and keep the heat inside your home for longer. A lower U value means that a unit of heat will take longer to pass through a material, in this case your walls.

  1. Solid Insulation plasterboards  – These are plasterboards with a foam based materiel on the back are stuck to your walls,
  2. Stud Wall – a wooden stud wall is built and attached to the brick wall and then filled with insulating material.
