STIFERITE RP


A high performance insulation board manufactured from CFC or HCFC free, closed cell rigid polyisocyanurate polyiso foam. It's covered on both side with multilayer facing, & bonded to one side with a 13 mm (1/2 inch) plasterboard.

The RP panel is excellent for insulation of internal walls & suspended metal frame ceilings. An easy system that can be applied on both walls and ceilings and allows the energy efficiency of existing buildings to be improved with quick installation causing minimal disruption that can be carried out without impairing the safety of the rooms. REWS approved for Roof Installation Scheme.

Internal thermal insulation inevitably leads to a reduction in usable space. To limit the reduction of living spaces, it is therefore important to use STIFERITE RP which has excellent insulating properties

The benefits of STIFERITE RP


  • STIFERITE RP insulate very well and save energy and usable space
  • excellent reaction to fire performance: STIFERITE RP panels obtain reaction to fire Euroclass B s1 d0
  • 2 in 1 solution that saves time & reduces costs
  • STIFERITE RP panels are light and easy to handle
  • rigid polyurethane foam is easily workable and can be cut or milled using ordinary construction site tools
  • STIFERITE RP can be made to the same height as the rooms to be insulated to reduce waste and installation times (upon request and quantity to be determined)
  • STIFERITE thermal insulating materials are environmentally friendly and have a positive ecobalance: the resources used to manufacture them are returned to the environment, in the form of energy saving and reduction in harmful emissions, right from the first heating season. STIFERITE has carried out LCA (Life Cycle Assessment) studies and provided environmental declarations for its products (EPB)
  • STIFERITE RP has a layer resistant to the passage of water vapour on the hot side
  • STIFERITE RP panels are suitable for installation on walls with glue and anchor bolts or on a metal frame
  • the bonding to plasterboard is carried out at the factory to allow quick & safe installation
  • excellent mechanical performance and impact strength
