Safire® Raised Access Floor Barriers are purpose manufactured from rock fibre material to seal the void between a raised access floor and the floor slab, thus preventing the spread of fire and smoke within concealed floor spaces and at junctions between floor and walls.
Access Floor Barriers are compression fitted into the void and the thickness of the access floor barrier should be 5% to 10% higher than the measured height of the void.
For voids over 100mm high, securing clips are provided for extra support. The direction of these are staggered such that each length of access floor barrier is supported.
Access floor Barriers are supplied in lengths of 1200mm to the correct height as specified by the site. Barriers are butt jointed to form a tight seal between adjoining lengths.
Installation is continued in this way with barriers at 10m or 20m as required by Building Regulations.
Temporary pinning or taping together of sections may be carried out if desired to avoid accidental disturbance before the installation of the access floor.
For barriers over 100mm high, special securing clips are provided for extra support. the direction of these alternates such that each length of access floor barrier is supported on both sides. Clips are supplied pre-cut to penetrate approx. 75% of the barrier thickness and should be fitted at 300m centres, or 200mm centres if the barrier is over 450mm high.
The barriers can be mechanically fixed to the structural floor as required.
Safire® Raised Access Floor Barriers are available from a national distributor network, enabling fast delivery to site directly from stock.
