What is EWI?

What is External Wall Insulation?

An External Wall Insulation (EWI) system comprises rigid insulation boards fixed to the exterior walls of a property creating a ‘thermal jacket’, which are then over-coated with a weather protective, breathable, hard wearing, attractive render finish. This improves the building's energy efficiency.

EWI systems consist of an insulant, suitable beads and fixings and an attractive finish, usually a render or similar decorative coating.
