Mannok Thermal PIR Rigid Insulation Board is a high-performance insulation solution designed for floors, fixings, framed walls, and pitched roofs. It’s ideal for both new builds and refurbishments, offering dependable thermal performance with straightforward installation.

• Dimensions: 1200 × 2400 mm panels with thickness options from 25 mm to 150 mm, giving flexible coverage for varying project requirements.
• Thermal Conductivity: 0.022 W/mK PIR core to minimise heat loss and help achieve lower U-values. For example, 100 mm thickness yields a U-value of about 0.22 W/m²K.
• Construction & Durability: PIR core with aluminium facings on both sides provides stiffness and long-term stability, with compressive strength over 150 kPa.
• Environmental Certification: Zero ODP and low GWP, with British Board of Agrément (BBA) certification for proven performance.
• Lightweight & Easy to Install: Easy to handle, cut, and fit on site, saving time and labour; suitable for use with underfloor heating.
• Versatile Applications: Suitable for floors, framed walls, fixings, and pitched roofs—appropriate for both new builds and refurbishments aiming to upgrade thermal performance.
• Thermal Resistance Enhancer: Low emissivity foil facing increases resistance in cavities and cladding by reflecting heat transfer.

By choosing Mannok Thermal PIR Rigid Insulation Board, you’re investing in improved energy efficiency, lower running costs, and a smaller environmental footprint. The robust, lightweight panels support load-bearing applications while delivering superior insulation for year-round comfort.
