• Mannok Therm Cavity / MC PIR insulation is a high performance, fibre free board, with a rigid thermoset insulation core and faced on both sides with a low emissivity composite foil facing, for use in partial fill cavity wall applications.
• The low emissivity foil facings increases the thermal resistance of the residual cavity and reducing the overall U-value of the wall.
• The good dimensional tolerances of the Mannok Therm Cavity / MC PIR insulation board enabling it to be tightly butted to form a continuous layer of insulation.
• Available with profiled T & G edges aiding installation and ensuring continuity of insulation across the joint.
