Product Description

Our Mannok Therm Wall (MW)/ Floor (MF) 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 low emissivity foil facings increase the thermal resistance an unventilated cavity adjacent to the insulation, reducing the overall U-value of the wall.

Specification: 

• Certified under BBA certificate number 07/4444
• Low thermal conductivity, minimising the thickness required to achieve the design U-value.
• Zero ozone depletion potential (zero ODP) and low global warming potential (GWP)
• Achieves an A+ rating when compared to the BRE Green Guide

Performance & Properties: 

• Board size: (mm)1200mm x 2400mm
• Thickness: (mm)20mm – 200mm
• Thermal Conductivity (λ): 0.022w/mk
• Facers: Low emissivity foil facers
• Core water vapour resistivity: ≅300MNs/gm
• Compressive strength: >140kPa

Them Wall (MW) Applications: 

• Insulating timber frame cavity walls
• Insulating steel stud frame cavity walls
• Insulating solid walls with internal dry lining – insulation boards fixed to battens
• Insulating solid walls with internal dry lining – insulation boards fixed by battens
• Insulating timber frame walls with weatherboards
• Insulating a loft or attic wall in pitched roof space

Them Floor (MF) Applications: 

• Insulating solid ground floors below ground bearing slab
