EWI is one of the best ways to improve your home’s energy efficiency, reduce heat loss and modernise the exterior appearance — all in one installation.
​
What Is External Wall Insulation (EWI)?
External Wall Insulation involves fixing insulation boards to the outside of your property, then applying a reinforced base coat and a breathable, weatherproof render system such as silicone render.
This creates a warmer, more energy-efficient home while giving your exterior a fresh, modern look.
