ABOUT External wall insulation

Did you know that your heating bills could be reduced by up to 40% with EWI?

External Wall Insulation (EWI) is the perfect solution for enhancing your home’s energy efficiency and cutting down those heating bills. By wrapping your property in a sleek layer of insulation, EWI keeps your space cosy in the winter yet cooler in summer. It’s not just about comfort— this retrofit system can lead to serious savings on energy costs!

Plus, with its hydrophobic features, EWI seals your home against water ingress, protecting it from damp and mould while maintaining its structural integrity, especially in beautiful areas like Torquay, Exeter, Paignton, Totness, and all areas of Devon.

What is External Wall Insulation?

Great question! External Wall Insulation or EWI consists of various materials and thicknesses tailored to the specific needs of your property. This insulation system is applied to the exterior walls of your home, creating a thermal barrier that enhances comfort and efficiency.



EWI can be installed to most property types as long as the correct materials are used.

EWI is most commonly finished with a pre-coloured silicone render but it can also receive brick effect imitation which looks incredibly realistic and also comes in a variety of colours to suit your preferences. This is a great way to stay in keeping with the general area of the property if that is required.
