An external wall insulation (EWI) system consists of tested components for insulating the exterior of buildings. It provides an excellent long-term investment in your house. You will benefit immediately from a cosier home and can reduce your energy costs from the very first hour. Insulating boards are placed on the external surface of all the vertical walls of a building and then covered with a protective, decorative render. This protects the building from fluctuating weather conditions, reduces heat losses from inside the building and will prevent external temperature changes from affecting the interior climate. EWI keeps homes warm in winter and cool in summer, ensuring a home with a pleasant atmosphere by eliminating sharp and high changes in indoor temperature. EWI will also reduce energy consumption in terms of energy consumed for heating and cooling.
