IMPORTANT: On 1 September 2017, Celotex took the precautionary measure to temporarily suspend the supply of Celotex FR5000, Celotex CG5000, Celotex CF5000 and Celotex SL5000 while we investigate the results of recent tests (Parts 6 and 7 of British Standard 476). Materials relating to these products are for information only.
With low emissivity textured aluminium foil facings, FR5000 is manufactured from rigid polyisocyanurate (PIR) using a blowing agent that has low global warming potential (GWP) and zero ozone depletion potential (ODP).
- Board size: 1200 x 2400mm
- Thickness : (Currently Suspended) 50-150mm
- Lambda: 0.021 W/mK
- Facer: Super low emissivity textured aluminium foil facings
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
