The FV144 Large Ventilated Cavity Barrier is a fire-rated solution specifically designed for use in external wall cavities at critical locations such as compartment floors, around windows and doors, and within uninsulated cavities requiring permanent ventilation. Engineered for cavities up to 450 mm in depth, FV144 incorporates a 6 mm thick barrier and maintains a free air gap of 44 mm. During a fire, the barrier expands to close the gap between its leading edge and the cladding’s internal face, providing up to 180 minutes of fire resistance for both integrity and insulation, depending on the construction of the external walls.
