Product Information
Unilin Thin-R Roof/Floor PIR Insulation 70mm is a rigid polyisocyanurate (PIR) insulation board with composite aluminium foil facings on both sides, certified to EN 13165 and BBA approved for use in ground supported and suspended floors, as well as pitched roof applications.
Designed to optimise thermal performance in space constrained environments, the insulation board has a thermal conductivity of 0.022 W/mK and an R-value of approximately 3.18 m²K/W, making it compatible with underfloor heating systems.
Measuring 1.2m × 2.4m (covering 2.88m²), the board installs in staggered, break bonded layout with tightly butted joints. Perimeter strips are available for edge detailing to reduce thermal bridging and maintain continuity. Its closed cell structure offers moisture resistance, and the composite foil enhances airtightness and low emissivity performance.
- Dimensions 1 200 × 2 400 mm provide 2.88 m² coverage per board
- Thermal conductivity 0.022 W/mK yields thermal resistance of ~3.18 m²K/W
- Compressive strength 150 kPa at 10 % compression supports floor loads
- Closed-cell PIR core and foil facings resist moisture and improve airtightness
- BBA certified for floor and pitched roof use
