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 the course of a fire this 'chimney effect' is an open path for the spread of fire, both vertically and horizontally, behind the cladding system.

A potential fire spread risk with rainscreen cladding in the 'chimney effect' of the ventilation space.

Fire rated cladding seals maintain the ventilated cavity in normal conditions, leaving a continuous free air space, but, in the event of a fire, the intumescent fire barrier will quickly expand to seal off the cavity to prevent the spread of fire.
