25mm rigid PIR insulation board, supplied in 2400mm × 1200mm sheets with aluminium foil facings on both sides. Manufactured to BS EN 13165 with a typical thermal conductivity (lamb da) of 0.022 W/mK — the highest-performing common rigid insulation per millimetre of thickness. The 25mm board is most often used for thin upgrade applications: insulating behind dot-and-dab plasterboard, lining out cold spots, topping up an existing wall build-up, or as a thin layer between battens. Lightweight, dimensionally stable and easily cut on site with a fine-toothed saw or sharp knife. Sold per sheet. Show more
