COSY WALL
INSULATION

CosyWall Insulation (CWI) is an external wall insulation system (EWCIS) designed to insulate the walls of older homes. It provides thermal and acoustical insulation to existing wall cavities and is installed without the cost and hassle of removing the internal linings. Installation is done via small holes through the external cladding, or from inside via holes in the internal linings. The result is high installed R-values and a warm cosy home. CosyWall insulation has been successfully growing since 2002 based on three core principles;

- Using a Great Product.
