Cavity wall insulation in West London
Help your walls hold on to heat with a cavity insulation system suited to your home.

A practical upgrade for your home.
Where suitable, insulating the gap between two masonry walls can improve the thermal performance of your home. RJM offers cavity wall insulation using a Therma-bead system, following an assessment of the property.
How we approach your installation
A survey checks the wall construction, cavity condition and exposure before work is recommended. Suitable cavities are filled with insulating material through carefully positioned access points, which are made good after installation.
What this can offer
- Improved wall thermal performance
- Less heat escaping through external walls
- An upgrade without reducing internal room space
