What is brick slip external wall insulation?
Brick slip external wall insulation is an EWI system finished with 10–20mm thick clay brick slips, bonded with adhesive onto a reinforced basecoat over the insulation and then pointed. Corner slips return around external corners so the finish reads as solid brickwork.
