150mm Mannok PIR Rigid Insulation Board

150mm Mannok Therm Floor / MF is a premium Insulation Board delivering outstanding thermal performance with a fibre-free construction. The product features a rigid thermoset insulation core with low emissivity composite foil facing on both surfaces.

With excellent compressive strength, 150mm Mannok PIR insulation resists the dead and imposed loads transmitted through floor structures. This makes it suitable for new build and refurbishment applications in commercial and domestic environments.

A key advantage of Mannok PIR Insulation Board is its compatibility with underfloor heating systems. The board performs particularly well in suspended timber floors, minimising heat loss and preventing air infiltration. It represents an effective solution for enhancing thermal efficiency in existing floor structures.

Previously marketed as 150mm Quinn Therm QF, this product continues to deliver the same proven performance.

Benefits of Mannok Therm Roof / MR (MR)

150mm rigid insulation performs excellently in pitched roof applications, whether for new construction or refurbishment projects involving roof stripping and recovery. Its structural strength allows it to span rafters and handle loads from roof coverings. The low emissivity facings enhance thermal resistance in the air space beneath the board, boosting overall roof thermal performance.

Benefits of Mannok Therm Wall / MW (MW)

150mm Mannok insulation works well for framed walls in new builds and dry lining applications in both new and refurbished properties. Low emissivity facings enhance cavity thermal performance and reduce wall U-values. The low thermal conductivity means less thickness is needed to reach target design U-values.

Benefits of Mannok Therm Floor / MF (MF)

The 150mm Insulation Board offers high compressive strength to handle dead and imposed loads in floor structures, making it suitable for most commercial and domestic settings. Appropriate for both new build and refurbishment work, it optimises Underfloor Heating System performance and upgrades thermal efficiency in existing floors. It reduces heat loss through suspended timber floors by minimising air infiltration. Low thermal conductivity reduces the thickness required to achieve desired U-values for improved energy efficiency.
