Celotex FI5000 Under Floor Heating Insulation - NEW!

Premium performance flooring insulation solution, suitable for concrete slab, beam and block, suspended timber and underfloor heating flooring applications.

Celotex FI5000 improved compressive strength underfloor heating insulation panels

Celotex's new FI5000 range of higher specification boards replaces FF4000 Range, and is purpose designed for use in internal underfloor, under-screed, heating applications. These boards have a higher compressive strength value of ≥175 kPa, which exceeds the standard GA4000 board range of (kPa) =≥140, making them more suitable to effectively retain the underfloor heating pipe clips in place, when the screed is poured over the underfloor heating system

Product Applications

Celotex FI5000 is a premium performance flooring insulation solution, suitable for a range of flooring applications including concrete slab, beam and block, suspended timber and underfloor heating applications.

FI5000 is suitable for concrete slab, beam and block, suspended timber and underfloor heating applications. FI5000 provides thermal performance benefits and has been designed with installation efficiency in mind. Featuring a super low lambda of 0.021W/mK, FI5000 achieves compliance to UK Building Regulations with better U-values and thinner solutions.

Celotex FI5000 combines best in class PIR insulation with an innovative composite facer featuring a built-in vapour control layer (VCL), enabling direct screed, without the need for an additional separating layer. FI5000 features an enhanced compressive strength value of ≥175 kPa making it the ideal solution for a range of flooring applications.

Board size: 1200 x 2400mm, Commonly available in thicknesses of 75mm, 100mm and 125mm.
