What is external wall insulation?

External wall insulation (EWI) is fitted to the outside of a building's wall and finished with a render or rainscreen system. It forms a thermal envelope around the property to prevent heat from escaping through the walls, typically combining an insulation layer with a reinforced base coat and decorative render for weather protection.
