The Requirements

External wall insulation is available for any pre-1900 property that requires it. Most homes before the 1920s have solid walls without a cavity, therefore external wall insulation is required for these types of property. We have a full range of external wall systems to suit all kinds of homes and buildings, and are happy to tailor our systems and services to meet your individual requirements.

The Process

With your free no obligation site survey, we go out and take all of the relevant measurements of your property. If you are interested and would like to continue with the service, we then forward you to the grant application and complete this for you if possible.

Our professionals are able to show you:-

  • The amount of money and energy that you save by having external wall insulation as well as loft insulation.
  • What ‘U-value’ your insulation will achieve once the work is completed. This is the rate at which heat will pass through the insulated wall. It should be no more than 0.30 watts per square metre kelvin.
  • Which materials they recommend, and why.
  • Whether there’s likely to be any build-up of moisture in the rooms once they’ve been insulated, and what you should do to mitigate this.

What sort of guarantee can I expect?

SWIGA (the Solid Wall Insulation Guarantee Agency). This will give you 25 years’ cover for defective materials, design or workmanship. You should also make sure the products and materials they’re using are BBA (British Board of Agrement) certified. Absolute Solar are both members of SWIGA and use BBA approved and certified products.
