Professional External Wall Insulation for Solid Wall (EWI Systems)

External Wall Insulation (EWI) provides a high-performance thermal barrier for solid wall homes, older buildings, single skin walls, prefab houses, and timber frame properties. With insulated layers applied externally, it reduces 35%–45% of heat lost through walls, lowers energy bills, protects brickwork, improves weatherproofing, cuts noise, and enhances your home’s exterior—all without reducing internal floor space.

Choice of Colours and Textures

Our huge selection of colours and textures allows homeowners to personalise their property. From flat renders to brick effect finishes with adjustable tints, you can create the exact look you want.

All funded installations are backed by a 25-year SWIGA guarantee, giving complete peace of mind and long-term protection.
