A CFC/ HCFC free, rigid polyisocyanurate foam insulation board, with a factory bonded 20 mm cork facing on the upper surface, and a glass tissue facing to the reverse.

Supertherm Plus is suitable for use beneath fully bitumen bonded reinforced bitumen membranes, and standard and polymer-modified mastic asphalt. The closed-cell foam core has a thermal conductivity of 0.027 W/mK and easily achieves required U-values with a minimum thickness, whilst the cork facing provides stability and a bonding surface.

Supertherm Plus is available in tapered format to improve roof drainage and a range of standard thicknesses to suit varying U-value requirements.

Features:

  • Totally CFC/ HCFC free (Zero Ozone Depletion).
  • Fire performance polyisocyanurate foam core.
  • For use with polymer modified or standard mastic asphalt, and fully-bonded reinforced bitumen membranes.
  • Industry standard PIR/ cork composite roofing board.
  • Full range of thicknesses to meet appropriate Building Regulations.
  • Lightweight and easy to handle.
  • Manufactured under quality assurance scheme BS ISO 9000: 2000.
  • High insulation value (PIR foam - aged thermal conductivity 0.027 W/mK).
  • Durable and maintenance free.

The product can be incorporated into a high performance waterproofing system, which if installed by a Permanite approved or registered contractor can be offered with a guarantee covering materials and workmanship for up to 20 years, depending on specification.
