FV050 product image

FV050 Small Ventilated Cavity Barrier is suited to an open state cavity of up to 50 mm, manufactured from a directionally expansive intumescent material encapsulated in a foil barrier.

Usage/purpose

FV050 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. In the event of a fire FV050 will expand to close the external wall cavity, providing effective fire resistance, for integrity and insulation for up to 120 minutes depending upon the construction of the external walls. FV050 is designed for use within a 50 mm cavity, and once installed will close the remaining free air gap (in front of the 6 mm thick cavity barrier) of 44 mm.
