Professional external wall insulation (EWI) systems transform solid wall properties, reducing heat loss by up to 45% while improving appearance. We install premium insulation boards with decorative renders or cladding, creating weatherproof, energy-efficient facades with comprehensive guarantees.
External Wall Insulation (EWI) is the optimal solution for insulating solid wall properties that lose heat rapidly through uninsulated masonry. By installing high-performance insulation boards to external walls and finishing with protective renders or cladding, we reduce heat loss by up to 45%, dramatically lower energy bills, improve comfort, and transform your property appearance while protecting brickwork from weathering.
We offer multiple EWI systems to suit different property types, budgets, and aesthetic preferences. Insulation options include expanded polystyrene (EPS) for cost-effectiveness, mineral wool for fire performance and breathability, or phenolic boards for maximum thermal efficiency with minimal thickness. Finish options include through-coloured silicone renders (self-cleaning and flexible), acrylic renders, brick-slip cladding for traditional appearance, or timber/composite cladding systems. All systems include proper detailing for windows, doors, and rainwater goods.
EWI provides multiple benefits beyond reduced heating costs. It protects your property from weather damage, eliminates cold bridging and internal condensation issues, reduces external noise transmission, requires no internal disruption or space loss, and dramatically improves kerb appeal and property value. Our systems come with comprehensive 25-year guarantees covering materials and workmanship. We handle all aspects including building regulations approval, ensuring complete compliance and peace of mind. Grants and funding may be available for eligible properties.
