TENMAT offers Ventilated Fire Barriers suitable for a wide range of cavity sizes and constructions. Modern constructions often require external cladding, external facades and rainscreen systems to be held away from the building structure to allow ventilation and improve the building energy efficiency.
This resulting cavity creates a serious fire protection threat to structures and people. The void acts like an open chimney and allows the fire to spread quickly both vertically and horizontally around the building. TENMAT’s range of Intumescent Ventilated Fire Barriers or ‘Open State’ Cavity Fire Barriers are designed to maintain the ventilated cavity in normal conditions but will rapidly expand to seal off the gap in the event of a fire.
