Vertical full-fill cavity barriers

Tenmat’s NVFB-LD (low density non-ventilated fire barrier) is highly compressible designed to maintain fire resistance performance within external wall cavities, without applying pressure to distort the plank.  Tenmat NVFB-LD is 45kg/m3 can be compressed 20mm onto the reverse of VulcaLap although is fire tested with only 2mm compression.

Plank infill

The overlap of VulcaLap planks inevitably has a ‘blind-spot’ requiring a small infill barrier.  This requires the 110kg/m3 NVFB cut to 12x15mm, screwed in line with the perpendicular barrier, i.e. vertically-laid planks require PBS barrier at the horizontal intumescent barrier position (VFB-Plus), as show below.

Horizontal ventilated cavity barriers

Tenmat’s VFB Plus Ventilated Fire Barriers are ’open state’ cavity fire barriers for ventilated cavities of up to 450mm. Each VFB Plus consists of a specially formulated fire rated stone mineral wool section with an integral high expansion intumescent seal fixed to the leading edge.

Horizontal – shallow ventilated cavity barriers

Tenmat’s FF102/50 Ventilated Fire Barriers is a shallow ’open state’ cavity fire barriers for ventilated cavities less than 50mm. The FF102/50 is identical high expansion intumescent as found on the front of the VFB Plus. This is also fixed as shown on the face of the cladding support rails to eliminate the blind-spot on the front of the rail.
