Improves cladding performance
Creates a fire barrier within the cladding
30-120 minutes rating
Horizontal and Vertical use
Suitable for ventilated cavities from 15mm
Tested to BS 476Part 20
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.
The Astroflame range of fire rated cladding seals will maintain the ventilated cavity in normal conditions, leaving a continuous free air space, but in the event of a fire, the intumescent ventilated fire barrier will quickly expand to seal off the cavity to prevent the spread of fire.
