What Is External Wall Insulation (EWI)?

External Wall Insulation (EWI) is a high-performance insulation system applied to the outer walls of a building. It involves fixing insulating boards to the external surface, followed by a protective render or decorative finish. This method forms a continuous thermal envelope, significantly reducing heat loss and improving overall energy efficiency.

EWI not only enhances thermal comfort but also modernises the external appearance of properties, making it a practical and aesthetic investment.

What Property Types Are Best Suited for EWI?

External Wall Insulation is particularly effective for:

• Older properties with solid walls (common in pre-2000 homes)
• Detached and semi-detached houses
• Terraced homes lacking cavity wall insulation
• Properties undergoing renovation or retrofit upgrades
• Homes with poor energy ratings (BER improvements)
