What is External Wall Insulation?
External Wall Insulation (EWI) is a high-performance thermal shell applied to the outer face of your property. It consists of an insulation layer fixed to the existing walls, finished with a protective, weather-resistant render. This system effectively 'wraps' your home in a thermal blanket, preventing heat from escaping through the masonry.
By upgrading your property with EWI, you eliminate cold spots and dampness while significantly reducing energy consumption. It is the most effective way to improve the thermal efficiency of solid-wall homes in London, providing a contemporary aesthetic update alongside substantial long-term savings on utility bills.
Key Benefits of External Wall Insulation

Slash your heating costs by up to 40% with high-performance thermal barriers that trap warmth inside.
Prevent Damp & Mould
Moving the dew point to the exterior protects your masonry from condensation and structural damage.
Increase Property Value
Improve your EPC rating and modernize your home's appearance, making it more attractive for future buyers.
Stunning Curb Appeal
Choose from a wide variety of textures and colors in silicone or brick slip finishes for a professional look.
Eco-Friendly Living
Reduce your carbon footprint by minimizing energy waste, contributing to a more sustainable future.
Better Soundproofing
