Brick slip external wall insulation in Leytonstone

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.
