FAQ

Do I need planning permission for EWI?
Usually, it falls under permitted development, but if your home is in a conservation area or is a listed building, you may need consent. We can help advise on this.

How long does the installation take?
A typical semi-detached house takes about 2 to 3 weeks, depending on the weather, as the various render layers need proper drying time.

Will EWI stop damp and mould inside my house?
Yes. By warming the external walls, EWI moves the dew point to the outside, preventing condensation from forming on cold internal surfaces, which is the main cause of mould.
