PFC Corofil Cavity Fire Barrier CCFB is a full fill cavity fire barrier manufactured from a 100mm thick low density stone wool product installed between the inner and outer substrates of a masonry façade to reinstate the fire resistance performance of the cavity. The lighter density allows greater scope for compression when installing within brickwork cavities when using wet mortar.
PFC Corofil cavity Fire Barrier has been tested to EN1366-4:2021 and will provide up to 120 minutes integrity and 60 minutes insulation fire resistance performance (please see the tables on page 4 for the full fire resistance performance based on cavity widths and orientation).
