Insulation is always the first type of measure to consider when trying to cut your energy costs or carbon emissions. Cavity Wall Insulation is one of the most cost-effective insulation measures.

Costs and Benefits

The cost of the measure depends on the mount of wall that can be insulated. A typical mid-terrace house will cost around £350, and an end-terrace or semi-detached house £500.With normal weather and standard occupancy, you should get your money back in less than 3 years*.


Materials and Guarantee

All cavity wall insulation in housing done by ecologic-energy uses materials approved by the BBA, the UK’s body responsible for testing and approving materials. ecologic-energy is also accredited by the BBA as a PAS2030 installer. The completed works are guaranteed for 25 years

through the Cavity Insulation Guarantee Agency, CIGA.

Installation

Installation for a typical home takes about 2-3 hours. All the work normally takes place outside of the home. Holes are drilled in the wall and the insulation injected. Watch the short video for details of how it is done.
