Mannok 100mm PIR Insulation

Mannok Therm Floor / MF 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 high compressive strength of Mannok Therm Floor / MF enables it to withstand the dead and imposed loads transmitted through the floor.

Mannok Therm Floor / MF is suitable for new build and refurbishments projects in both domestic and commercial build. With specific properties that optimise the performance of underfloor heating.

For suspended timber floors in particular, Mannok Therm Floor / MF reduces heat loss by an air infiltration method, making it the ideal solution for upgrading the thermal performance of existing floors.
