Mannok Cavity Board - All Sizes Thickness:80mm 18 W/m2K and lower shouldMannok is a polyisocyanurate (PIR) insulation board ideally designed to be used in masonry walls with partial fill cavity insulation. These boards are crafted with a core of PIR foam connected on both sides to the composite facings.
