Mannok 30mm PIR Rigid Floor Insulation Board

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 applied to both surfaces.

With its robust compressive strength, this 30mm Mannok PIR insulation board withstands both dead and imposed floor loads effectively. It suits new build and refurbishment projects across commercial and domestic applications.

A key advantage of Mannok PIR Insulation Board is its compatibility with underfloor heating systems. It performs particularly well in suspended timber floors, reducing heat loss and preventing unwanted air movement. This makes it an excellent upgrade for improving thermal efficiency in existing floor structures.

Previously marketed as 30mm Quinn Therm QF, this product maintains the same proven performance standards.

Benefits for Pitched Roof Applications

30mm rigid insulation performs excellently in pitched roof installations, whether for new construction or refurbishment work involving roof stripping and replacement. Its structural strength allows it to bridge rafters and handle loads from roof coverings. The low emissivity facings enhance thermal resistance in the air space above the insulation, boosting overall roof thermal performance.

Benefits for Framed Wall Applications

This 30mm insulation board works well for framed walls in new build projects and dry lining in both new and refurbished properties. The low emissivity facings improve cavity thermal performance and reduce wall U-values. Its low thermal conductivity means thinner installations can achieve target design U-values.

Benefits for Floor Applications

The 30mm Insulation Board delivers high compressive strength, enabling it to resist dead and imposed loads transmitted through floors. It suits most commercial and domestic settings in both new build and refurbishment scenarios. The product optimises Underfloor Heating System performance and effectively upgrades thermal efficiency in existing floors. It minimises heat loss from air infiltration in suspended timber floors. Low thermal conductivity reduces the thickness needed to meet your target U-value for enhanced energy efficiency.
