100mm Celotex FI5000 is a premium flooring insulation board with enhanced thermal performance as well as an A rating when compared to the BRE Green Guide and an innovative cement compatible composite facer with a built-in vapour control layer (VCL), enabling direct screed, without the need for an additional separating layer.

FI5000 has an enhanced compressive strength value of ≥175 kPa making it the ideal solution for a range of flooring applications. Featuring a super low lambda of 0.021W/mK, FI5000 achieves compliance to UK Building Regulations with better U-values and thinner solutions.

Application:

• Basements
• Beam and Block Floors
• Concrete Slab Floors
• Upgrading Concrete Slab Floors
• Suspended Timber Floors
• Underfloor Heating

Advantages of 100mm Celotex FI5000:

• Lower thermal conductivity value (0.021 W/mK) compared with other typical PIR insulation boards providing enhanced thermal performance,
• Ensures minimal downward heat loss into structure,
• Enhanced compressive strength value of ≥175 kPa
• Highly resistant composite facer featuring a built-in vapour control layer (VCL), enabling direct screed, without the need for an additional separating layer,
• Uses the foam structure to ensure better pipe clip retention,
• Is easy to cut and install,
• Future proofs the energy performance of new and existing buildings, Is CFC/HCFC free with zero ODP and low GWP and CE marking compliance to BS EN 13165
