Mannok Therm Wall / MW PIR Insulation
Mannok Therm Wall / MW 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.
The low emissivity foil facings increase the thermal resistance an unventilated cavity adjacent to the insulation, reducing the overall U-value of the wall.
The good dimensional tolerances of the Mannok Therm Wall / MW PIR insulation board enable it to be tightly butted to form a continuous layer of insulation. Joints can then be easily taped with an aluminium foil tape to provide an effective vapour control layer.
