Many rainscreen and cladding systems are designed with an open cavity to provide back ventilation. The cavity acts like an open chimney to allow for moisture dissipation and to create a back pressure to repel rain ingress.However, in a fire situation this chimney effect creates an open path for the hidden spread of fire both vertically and horizontally behind the cladding system.Building Regulations require that Fire Barriers be installed within the cavity to prevent fire spread. TENMAT’s range of Ventilated Fire Barriers maintain the ventilated cavity, but, in the event of fire, the intumescent Ventilated Fire Barriers quickly expand to seal off the cavity to prevent fire spread.
