Premium EWI render systems & finishes
Choose system-approved renders — silicone thin-coat, acrylic or hybrid silicate-silicone — for reliable weather protection, breathability and long-term appearance. Plan render colours early to coordinate elevations and detailing. Specify with confidence for both refurbishments and new builds. Looking for the best silicone render for UK climate? We’ve got you covered.
Complete EWI components
Combine insulation boards (EPS/XPS) with adhesives & basecoats, mesh reinforcement and wall primers to build robust external wall insulation systems. This ensures impact resistance, vapour permeability and reliable performance in UK exposure classes. Ideal for EWI systems for energy-efficient homes.
