Are you thinking of insulating the walls of your home?

Through this website and our Facebook Group page: An EWI Failure (External Wall Insulation) Support Group. We would like to try to help you avoid the pitfalls you may encounter with EWI. By providing a place for people to share their experiences we hope to help to raise awareness of issues with wall insulation. Bringing people together to have a stronger voice will hopefully mean that in the future the industry will serve people better.

This website aims to help people understand that insulating the walls of your home may not be as straightforward as the industry leads us to believe. This site shows our experience with insulating a house. We found there were lots of things we wish we had known before embarking on this journey.

house4As a minimum, if you are considering insulating your house please:

  • Search for ‘failures’ first e.g. External Wall Insulation failures, EWI failures, Solid Wall Insulation failures, SWI failures, Cavity Wall Insulation failures, CWI failures or Internal Wall Insulation failures or IWI failures.
  • Go to British Board of Agrément (BBA) website, put in name of manufacturer of the system you intend to use and find the relevant BBA Certificate. Read what preparation may be required to make a building ready for the installation, comparing this with your property, and read how the installation should be done.
  • Involve a manufacturer from the beginning, (at the planning stage), ensure you get design plans, don’t rely on the contractor alone. Don’t assume that because you are employing a manufacturer “Trained” or “Recognised” contractor they will know how to do the installation properly.

house2Despite using an accredited and manufacturer approved contractor, we are now faced with an unaffordable £58,000 estimate to put things right. We have been left with a house which has been devalued in the region of 25-30% and when added to various costs we have already paid means we are some £130,000 out of pocket.

At present we find there is no help for people in our situation other than court proceedings – which at up to £50,000 are probably out of reach for most people. There is no Legal Aid for this type of litigation.

Our experience has been with External Wall Insulation (EWI) also known as Solid Wall Insulation (SWI) but, while trying to find a solution to the water ingress problem we have been left with following the retro-fit/domestic refurbishment of EWI to our house, we have discovered that there are problems with all forms of wall insulation – whether External Wall Insulation (EWI), Solid Wall Insulation (SWI), Cavity Wall Insulation (CWI) or Internal Wall Insulation (IWI).

In 2013 when we first looked into EWI and The Green Deal we only saw positive promotion of these products by the insulation industry and The Energy Saving Trust. We didn’t think to look for problems and failures so don’t know how much information was available back then, but there is a lot appearing now. It is interesting to note that External Wall Insulation (EWI) is now more often being called Solid Wall Insulation (SWI).
