Tenmat FF102 Ventilated Fire Barriers
TENMAT's FF102 Ventilated Fire Barriers are designed for use in ventilated cavities behind cladding and rainscreen systems, offering high-performance fire protection in modern constructions. These ‘Open State’ Cavity Fire Barriers maintain ventilation during normal conditions but rapidly expand in the event of a fire to seal the cavity, preventing vertical fire spread. Suitable for 25mm and 50mm gaps, FF102 strips are rigid, high-expansion intumescent seals encased in aluminium foil and can be mechanically fixed in a wide range of construction types. Extensively fire-tested and rated for up to 60 years of service life under New Zealand conditions, they provide a simple, reliable, and site-friendly installation solution.
