Building Regulations require that fire barriers be installed within the cavity of rainscreen/cladding systems to prevent the spread of fire.
Safire ® Ventilated Rainscreen Barriers allow the cavity to be retained for normal functions, but in the event of fire the intumescent Ventilated Rainscreen Barrier quickly expands to seal off the cavity to prevent the spread of fire.
