Offering best in class performance, Celotex FR5000 is over 100% more thermally efficient than many mineral fibre products and up to 10% better than typical PIR. Developed specifically for use in pitched roofs, floors and walls, Celotex FR5000 is a high performance insulation board that:

  • Has a lower thermal conductivity value (0.021W/mK) compared with other typical PIR insulation boards providing enhanced thermal performance and better U-values
  • Has super low emissivity value 
  • Achieves an 'A+' rating when compared to the BRE Green Guide
  • Has Class 0 fire performance throughout the entire product in accordance with BS 476
  • Is suitable for a range of applications including pitched roofs, walls and floors
  • Future proofs the energy performance of new and existing buildings
