High performance, fibre free board, with a rigid thermoset insulation core and faced on both sides with a low emissivity composite foil facing, for use in partial fill cavity wall applications.
The low emissivity foil facings increases the thermal resistance of the residual cavity and reducing the overall U-value of the wall.
The good dimensional tolerances of the Mannok Therm Cavity / MC Wall PIR Insulation board enabling it to be tightly butted to form a continuous layer of insulation.
Specification:
- Therm Cavity Wall board sizes are co-ordinated with standard wall tie spacings
- Tongue and groove edging for continuity of insulation across joints
- 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): 450mm x 1200mm
- Thickness (mm): 25mm – 110mm
- Edge: Butt, tongue and groove
- Thermal Conductivity (λ): 0.022w/mk
- Facers: Low emissivity foil facers
- Core water vapour resistivity: ≅300MNs/gm
- Compressive strength: >150kPa
