Mannok Therm Roof / MFR-PLY PIR insulation is a high performance, fibre free board, with a rigid thermoset insulation core and faced with a low emissivity composite foil facing on the inner side and 6mm water and boil proof (WBP) plywood on the outer.

The low thermal conductivity, minimises the thickness required to achieve the design U-value while the composite board offers rapid coverage and straightforward installation.

Mannok Therm Roof / MFR-PLY PIR insulation boards allow for the installation of a roof structure in one operation, as the product provides the deck, insulation and vapour control layer all-in-one.

Mannok Therm Roof / MFR-PLY PIR insulation is compatible with a wide variety of weathering systems as it helps reduce the risk of condensation and eliminates the need for ventilation beneath the deck.
