Tenmat FF102/50 Fire Barrier
Tenmat’s FF102/50, Ventilated Cavity Fire Barriers, are manufactured from a low smoke zero halogen high expansion intumescent material. They are designed to reinstate fire resisting performance to external wall cavities that are required to be ventilated (open-state) in non-fire conditions.
The FF102/50 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.
In the event of a fire the FF102/50 intumescent material 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.
The FF102/50 is designed for use within cavities of up to 50mm and once installed will close the remaining free air gap in front of the 6mm cavity barrier of up to a maximum of 44mm (depending on construction type).
•An “open state” cavity fire barrier for use horizontally within uninsulated, ventilated and drained cavities
•Fire Rated for up to 120 minutes for both integrity and insulation when tested to the general principles of BS EN 1363-1 following ASFP TGD 19 guidance
•Ventilated design – developed to allow maximum ventilation and drainage of cavities reducing the need for cavity trays or weepholes
•Suitable for “open-state” ventilated cavities up to 50mm wide
•Provided in strips of 1m long, 75mm wide and 6mm thick
•Lightweight – designed to be easily and quickly installed
