80mm Mannok PIR Rigid Insulation Board

80mm Mannok Therm Floor / MF is a premium Insulation Board delivering outstanding performance with a fibre-free construction. The board features a rigid thermoset insulation core with low emissivity composite foil facing on both surfaces.

With excellent compressive strength, this 80mm Mannok PIR insulation handles floor loads effectively in both new build and refurbishment projects across commercial and domestic applications.

Key advantages of Mannok PIR Insulation Board include enhanced underfloor heating systems performance and suitability for suspended timber floors. It minimises heat loss and air infiltration, making it ideal for improving thermal efficiency in existing floor installations.

Note: 80mm Mannok Therm Floor / MF was previously marketed as 80mm Quinn Therm QF.

Benefits for Pitched Roof Applications

80mm rigid insulation suits pitched roof installations in new builds and refurbishment projects involving roof stripping and recovery. Its structural strength allows it to span rafters and manage roof loads effectively. Low emissivity facings enhance thermal resistance in air spaces, boosting overall roof thermal performance.

Benefits for Framed Wall Applications

80mm Mannok insulation performs well in framed walls for new builds and dry lining in refurbishment projects. Low emissivity facings improve cavity thermal performance and reduce wall U-values. Its low thermal conductivity means less thickness is needed to reach target design U-values.

Benefits for Floor Applications

The 80mm Insulation Board delivers high compressive strength to handle floor loads in commercial and domestic settings. Suitable for new build and refurbishment work, it optimises Underfloor Heating System performance and enhances thermal efficiency in existing floors. It reduces heat loss through suspended timber floors and air infiltration. Low thermal conductivity reduces the thickness required to achieve target U-values.
