Cavity wall insulation for wall to wall energy saving!
Did you know that around a third of the heat lost at home is through the walls?
Just insulating your cavity walls could save you around £160 a year on your fuel bills and 800kg of CO2.
Cavity Wall Insulation will help to create an even temperature around your home, help to prevent condensation on the walls and ceilings and can also help to keep your home cooler during summer hot spells.

Good to know…
The main insulation materials used are glass or mineral fibre that is chopped up and blown into the cavities. Some installers use Bonded bead (white polystyrene beads) and Urea formaldehyde foam (white foam).
If you want to be even greener and have a sustainably manufactured material used in your property as opposed to the standard glass or mineral fibre, then please express your requirements upon application to the service or during your free no obligation assessment, and we will advise of the options available to you. Please be aware that alternative materials will incur additional costs.
All systems have been tested, assessed and approved by the British Board of Agrément or the British Standards Institution. The material is guaranteed for 25 years against any defects. (Guarantees are provided by the Cavity Insulation Guarantee Agency - CIGA).
