External Wall Insulation in Dublin
External wall insulation (EWI) is the go-to solution for older Dublin homes built with solid walls that have no cavity to fill. Unlike cavity wall insulation, EWI wraps the outside of your home in insulated boards finished with a protective render, eliminating thermal bridging entirely.
Many homeowners combine EWI with attic insulation for maximum impact. When you insulate both the walls and the roof, you create a complete thermal envelope that can boost your BER rating by two or three grades. See our home insulation & grants guide for the full breakdown of available SEAI funding.
