Its primary use is for fire containment located between the concrete floor slab edge and exterior walls in high-rise building construction. DELTA®SAFING Mineral Wool BOARD can be used as a “poke through” fire barrier for part of a hourly-rated assembly in cracks, crevices, openings, and around penetrations.
