Thermal upgrade systems that cut heat loss, improve EPC ratings and finish in a full render colour range.
External Wall Insulation wraps a building in an insulation board finished in render, cutting heat loss through solid or poorly-insulated walls and improving its EPC rating without losing internal floor space. It's increasingly specified on social housing retrofit and decarbonisation programmes, as well as private refurbishment work.
