Are your walls suitable for insulation?

A cavity wall, as the name suggests, is one that has an empty space between the inner and outer walls. You can usually spot a cavity wall if the brickwork has an even pattern and bricks that are laid lengthways.


The majority of homes built after the 1930s have cavity walls. If you’re not sure, get in touch and we can take a look. If your walls are solid then solid wall-specific insulation is also available.

Why insulate your walls?

Cavity wall insulation can reduce the amount of heat loss giving you a warmer home and increased energy efficiency. It can also result in less sound penetration, making your home, or a specific area of your home much more soundproof! In addition to cavity wall insulation, underfloor insulation and loft insulation.

We also offer:

loft insulation installation
