The FF102/25 Ventilated Cavity Fire Barrier is constructed from a low smoke, zero halogen, high expansion intumescent material. Its primary purpose is to restore fire resistance to external wall cavities that must remain ventilated (open-state) during non-fire conditions. The FF102/25 is manufactured from a rigid intumescent material allowing it to be provided in a strip format, it is also covered with a protective layer of aluminium foil for ease of handling and increased durability. In the event of a fire the FF102/25 intumescent material will expand to close the external wall cavity, providing effective fire resistance, for integrity and insulation for up to 60 minutes depending upon the construction of the external walls.
