Is cavity wall insulation right for my home?

If your house was built in the last 20 years or so, the walls are probably already insulated. If you’re not sure whether a) your walls have cavities, or b) if you have cavity wall insulation already, we can help.

If your house was built after the 1920s, it is likely to have cavity walls. A cavity wall is made up of two walls with a gap in between, known as the cavity; the outer leaf is usually made of brick, and the inner layer of brick or concrete block.

Pre-1920 older houses are more likely to have solid walls. A solid wall has no cavity; each wall is a single solid wall, usually made of brick or stone.
