What is External Wall Insulation?

External Wall Insulation involves fixing insulation materials to the outer surface of exterior walls thereby wrapping the house in an insulating ‘blanket’. The insulation is then covered with a maintenance free render giving your property an additional protective layer and fresh new appearance. Our solution is available in over 800 colours, giving you the option to update and improve the look of your property while making it more energy efficient.

Up to 35% of heat loss from the average home escapes through wall spaces if not properly insulated. External wall insulation offers by far the simplest and most reliable solution for improved insulation performance. By wrapping your entire home in a consistent layer of insulation heat loss is dramatically reduced saving on heating costs which account for 75% of the average household energy bills. It is suitable for old and new buildings, individual houses, apartments and non-residential buildings. Installing External Wall Insulation is the biggest contributor to improving your BER rating.
