What are the Main Benefits of External Wall Insulation?
External Wall Insulation uses the fabric of the building like a storage radiator. Because the heat can no longer escape through the outer layer of insulation, it is reflected back into the living areas, creating a constant warm home.
It has various advantages which include improving the airtightness of a home (i.e. elimination of unwanted draughts through the building fabric), as well as substantially increasing the thermal performance of a dwelling without reducing the floor area. With up to 35% heat lost through external walls, EWI can help reduce your heating bills by up to 40%.
