Product Information

The 'engine' of a panel system is the insulation core. Kingspan's unique PIR insulation formula creates a superior closed cellular core fundamental to the panel system in terms of fire and thermal performance. This combined with the robust engineering of the Kingspan Roofliner panel, with its steel facings and superior joint design, make the Kingspan roof unparalleled as a weather-resilient, air-tight, low energy and highly fire resistant solution.
  • Certified FIREsafe PIR Sydtem
  • Superior R values
  • Durability- Long Term performance
Standard coatings: Colorbond Off-white to both faces.  Please contact us for other options to suit specific internal environments.

Exterior weatherproofing is provided by the overlaid single-ply membrane or standing seam – please refer to the applicable supplier of the specified system for details.
