About

External wall insulation is a type of home insulation that is placed on the outside of buildings. This type of insulation is more efficient than traditional insulation that is installed inside the walls. EWI insulation can be applied to both new and existing homes. Can be made from different materials, such as fiberglass, extruded polystyrene and polyurethane. These materials are environmentally friendly and have high thermal efficiency ratings.
