Class 4

FDEB4 is suitable for data centres and server room use. The result is a Class 4 elevated modular floor onto which IT components can be placed including server cabinets, uninterruptible power supplies and cooling systems.
Panels making up the system comprise of galvanised steel top and bottom sheets that are bonded to the core. A resilient covering is applied to the top and the panel is finished with an ABS edge band.
We’ve invested in research and development to optimise our energy and raw material usage. This system has EPD & HPD certification and is manufactured in our advanced, energy efficient manufacturing facility where 94% of the energy used is from sustainable sources.

Further information


The standard panel size for this system is 600 x 600mm.


600 x 900mm ‘oversize’ panels are available for perimeter detailing in this system.


Recommended for additional lateral stability in the following applications:

  • 600-800mm void heights: clip-on stringer system
  • >800mm void heights: screw-down stringer system

Underfloor Plenum

This system can be supplied with neoprene gaskets to minimise air loss through the raised floor surface from the underfloor plenum to aid air circulation, distribution and management.

Surface Finishes

A wide variety of surface finishes can be bonded to the top surface of the panel including HPL, Vinyl, Rubber, Linoleum & Marmoleum.
