External wall insulation
At Elqeni Construction, we specialise in high-performance external wall insulation (EWI) systems designed to significantly improve the energy efficiency and comfort of your property. Our team installs a layer of rigid insulation boards to the exterior of your building, followed by a protective render finish. This not only helps reduce heat loss and lower energy bills, but also transforms the appearance of outdated or weathered façades.
Our EWI solutions are ideal for properties with solid walls or poor insulation and are tailored to suit residential homes, commercial premises, and housing blocks across London. Every project is completed using breathable, weather-resistant materials to prevent dampness and prolong structural health.
We handle everything from preparation and insulation to rendering and final detailing, ensuring a clean, neat finish that’s both aesthetic and practical.
Whether you're looking to modernise your property, improve its EPC rating, or eliminate cold spots, Elqeni Construction delivers insulation that lasts, with clear communication and guaranteed results.
