VFB 120/120 - Ventilated Cavity Fire Barrier
Verified by manufacturer 6 months ago
IFCC
Certificate type
A cavity fire barrier system for ventilated cavities up to 450 mm.
Application
The VFB 120/120 can be mechanically fixed horizontally within ventilated cavities behind external wall systems to act as a cavity fire barrier, and can be complemented by the NVFB for vertical applications. Suitable for use within the majority of construction types.
Description
Tenmat VFB 120/120 Ventilated Fire Barriers are ’open state’ cavity fire barriers for ventilated cavities of up to 450mm. Each VFB 120/120 consists of a specially formulated fire rated stone mineral wool section with an integral high expansion intumescent seal fixed to the leading edge.
The VFB 120/120 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 spread within the external wall.
The products have 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 120/120s are mechanically fixed horizontally within ventilated cavities behind the external wall substrate following the fire compartment line. The VFB 120/120s 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.
