Brick Cavity Wall
Homes where the bricks are all laid in the same direction (see image 1) tend to have cavity walls. Cavity walls tend to be at least 280mm wide (see image 2) and are unlikely to be less than 250mm. The age of a house is another cavity wall clue. If it was built after 1920 (indicated by windows which are wider than they are tall - see image3), it probably has a cavity wall.

Solid walls will either be constructed of bricks or regular stone blocks (rather than randomly shaped stone cladding – see Random Stone). In a solid brick wall, some of the bricks are laid across the wall, to give it strength. Consequently the ends of the cross laid bricks are visible (see images 4 to 5) and not just the long side of the brick. Measured at the door or window (see Image 2), solid brick walls tend to be about 230mm thick. Solid Stone walls tend to be over 300mm thick.

Random Stone and Concrete Panel Cavity Walls
Random Stone walls (see image 6) are cavity walls where the outer layer is constructed from randomly shaped stone cladding rather than bricks. Cement is largely absent from Concrete Panel walls which are constructed from preformed concrete sections (see image 7).

How do I find out?
The Cavity Insulation Guarantee Agency (CIGA) has insured cavity wall insulation work since 1995. Phone CIGA on 01525 853 300 to find out if your home has guaranteed cavity wall insulation or use an alternative provider. Another way to tell if you have cavity wall insulation is to look for a regular pattern of drill holes in your cavity wall.
