Installation Guide:

• FireBlox™ Plus is supplied in slabs of 1200mm wide x 1000mm long x 100mm deep and should be cut to size on site to suit the cavity width allowing for relevant compression. Joints must be abutted tightly and sealed with 100mm aluminium foil tape.

• Two FB brackets to be used per 1 metre length fixed at a maximum distance of 250mm from each end, for lengths less than 500mm one bracket can be used, dimensional tolerance for bracket installation is +/- 20mm.

• Minimum one stainless steel fixing per bracket.

• FB brackets must penetrate not less than ¾ of the cavity width fixed through the middle of the barrier depth.

• FireBlox™ Plus can be face fixed in cavity widths between 20mm and 70mm with a 3mm compression. Fix using Grayson Multi-Purpose (MP) stainless steel screws, suitable for the width of the cavity barrier and substrate. The screw head must fully penetrate the face of the cavity barrier by at least 3mm and fixed at a maximum of 500mm centres.
