DCT Tenmat Fire Barriers

Modern construction often requires external cladding, external facades and rainscreen systems to be held away from the building structure to allow ventilation and improve the building energy efficiency. Within this void, it is essential to have a cavity barrier. 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 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. For vertical applications we recommend our non-ventilated “Closed State Cavity Barriers”.
