EWI wraps the building in a continuous thermal coat, eliminating drafts and modernizing the exterior with a premium finish.

Weather exposure in Cork

Cork experiences high rainfall and salt-laden winds, particularly in coastal areas. It is vital to use highly breathable render systems (like silicone or mineral renders) to allow structural moisture to escape while preventing rain penetration.
