External Wall Insulation (EWI) improves your home’s energy efficiency by adding a protective layer to the outside walls. This helps retain heat in winter and keeps interiors cooler in summer. Our EWI systems also enhance your home’s appearance, as they can be finished with a range of renders and colours. The insulation reduces heating bills, prevents damp, and improves comfort levels all year round. It’s a smart upgrade that boosts both value and efficiency.
