EWI System

Silicone Finish for Maximum Weather Defence

Our External Wall Insulation (EWI) systems already add warmth and energy efficiency — but the final layer is where we add even more value.

Every EWI installation is finished with a silicone-infused topcoat, designed to provide exceptional water repellency. This protective layer prevents water penetration, reduces staining and adds significant longevity to the system.

By combining insulation with silicone-enhanced render, you get superior energy savings and a highly weather-resistant exterior that performs all year round.

Extra Protection for Insulated Walls
Our External Wall Insulation (EWI) system doesn’t just improve thermal efficiency — we apply a silicone-infused finish layer so the outer surface has enhanced water shedding capability.
Combine insulation & weather-defence in one robust system.
