We specialise in delivering high-performance External Wall Insulation (EWI) solutions across Kildare, Dublin, Louth, Wicklow, and Meath, helping homeowners and commercial property owners significantly improve energy efficiency, reduce heating costs, and enhance building aesthetics. As experienced professionals in SEAI grant-supported insulation works, we streamline the process from assessment through to grant application and installation.
External Wall Insulation is one of the most effective upgrades for improving a property’s Building Energy Rating (BER) while also providing long-term financial and environmental benefits.
What is External Wall Insulation (EWI)?
External Wall Insulation (EWI) involves applying a layer of insulation material to the exterior walls of a property, finished with a protective render or decorative coating. It is particularly suitable for older homes, solid wall constructions, and commercial buildings that lack cavity insulation.
This system:
-
Eliminates thermal bridging
-
Improves airtightness
-
Enhances weather resistance
-
Modernises external appearance
