FB Cavity Barrier
FB Cavity Barrier is also well suited for attic venting. In that regard, it is mounted in the air gap at the eaves level.
In the case of a fire, the cavity barrier will instantly seal the cavity and prevent fire spread. It is tested according to sudden direct flame impingement ASTM 2912:13.
FB Cavity Barrier is available in fire classes EI30, EI60 and EI90.
Like other Firebreather products, the FB Cavity Barrier combines the need for adequate venting behind the cladding with the need to limit the spread of fire.
