    A high density, fire resistant sponge with a black or white intumescent coating on both main faces. These slabs are suitable for use as a permanent fire barrier in walls, floors and ceilings, or around services.

    – Due to its high density, it can be used for large openings in floors, walls and ceilings

    – Non-fibrous material is ideal for use in sterile areas or clean rooms

    – Ideal for use under raised flooring as a firebreak, providing 1-4 hours fire protection

    Envirograf NF Slab is cut to suit the opening size and you cut around any services
    like a jigsaw, adhering each section or joint with the jointing compound.
    Where services are PVC, i.e. Pipes and cables, Envirograf Wraps should be used,
    50mm wraps for two hour fire protection and 100mm wide wraps for four hour
    protection. The wraps can also be fitted around steel, copper and aluminium pipes to
    stop the pipes overheating and passing the heat from one side to the other of the fire
    barrier.
    When fitting NF Slabs in a floor opening and the mesh is being used to help supports
    the slabs, the wire mesh should be laid into the opening, bending up the sides and
    fixed with screws, raw-plugs and large washers, or split nailing with large washers.
    Then lay the slab on top of the mesh adhering all the sides with jointing compound
    and all cut joints. The whole barrier will dry hard in 10 minutes.
    Where cable trays pass through the barrier so Envirograf Intumescent E1/20/30
    should be fitted over cables.
