About this service
External Wall Insulation
External Wall Insulation (EWI) is the single most effective upgrade for reducing heat loss through solid or cavity walls. We install fully certified EWI systems (EPS, mineral wool and phenolic boards) that cut energy bills, eliminate cold bridging and qualify for government retrofit grants. The insulation board is mechanically fixed and adhesive-bonded, then finished in any render colour or brick slip of your choice. All systems carry BBA certification and a minimum 25-year guarantee.
