Mannok Therm Cavity MC PIR Insulation 1200x450x50mm

Mannok Therm Cavity / MC PIR Insulation – High-Performance Cavity Wall Insulation

Mannok Therm Cavity / MC PIR insulation is a high-performance, fibre-free board designed for use in partial fill cavity wall applications. Featuring a rigid thermoset insulation core and low emissivity composite foil facings on both sides, this insulation board enhances thermal efficiency by increasing the resistance of the residual cavity and reducing the overall U-value of the wall.

With excellent dimensional tolerances, the board fits tightly against adjacent insulation layers, forming a continuous and effective thermal barrier. Available with profiled tongue and groove edges, it aids installation while ensuring seamless insulation across joints.
