Tenmat - Model VFB 60/60 -Ventilated Cavity Fire Barrier
Tenmat’s VFB 60/60 Fire Barrier is an ’open state’ or ventilated cavity fire barrier for ventilated cavities of up to 450mm. Specially formulated for fire stopping: Each VFB 60/60 consists of a specially formulated fire-rated stone mineral wool section with an integral high expansion intumescent seal fixed to the leading edge. VFB 60/60 then leaves a maximum 25mm air gap to allow for drainage and maintain ventilation in normal use. In a fire situation, the intumescent seal rapidly expands to seal off the air gap and prevent vertical fire from spreading within the external wall.
The products hold 3rd Party Certification after having undergone extensive fire testing following the principles of BS EN1363-1 and in accordance with ASFP TGD19 (Fire Resistance Test for ‘Open-State’ Cavity Barriers). The VFB 60/60s are mechanically fixed horizontally within ventilated cavities behind the external wall substrate following the fire compartment line.
The VFB 60/60 ventilated cavity fire barriers are used horizontally and can be installed in conjunction with Tenmat NVFB Non-Ventilated Fire Barriers which provide vertical fire separation along fire compartment party wall lines.
