What Is External Wall Insulation?
External wall insulation (EWI) involves fixing an insulating layer to the outside of your property, followed by a protective render or decorative finish. It improves thermal performance, reduces heat loss, and enhances the appearance of older buildings.
Why Invest in External Wall Insulation?
Insulating your external walls can cut heat loss by up to 45%, leading to lower energy bills and improved comfort all year round. It’s ideal for properties without cavity walls or where internal insulation isn’t practical.
Key benefits include:
Significant reduction in heating costs
Improved energy efficiency (EPC rating)
Reduced condensation and damp issues
Enhanced kerb appeal
Added property value
