FV025 Small Ventilated Cavity Barrier is suited to an open state cavity of up to 25 mm, manufactured from a directionally expansive intumescent material encapsulated in a foil barrier.
FV025 is a fire rated product designed to act as an external wall cavity barrier at the required locations such as compartment
floors, around windows, doors, etc. and within uninsulated cavities requiring permanent (open-state) ventilation, to reinstate fire resistance performance. In the event of a fire FV025 will expand to close the external wall cavity, providing effective fire resistance, for integrity and insulation for up to 60 minutes depending upon the performance ability of the external walls. FV025 is designed for use within a 25 mm cavity, and once installed will close the remaining free air gap (in front of the 4 mm thick cavity barrier) of 21 mm.
