Where fire resistance-rated floor or floor ceiling assemblies are required where the unprotected void at the edge of slab becomes a chimney or flue for fire to rage up the inside of the building, transmitting fire from floor to floor. Voids created at the intersection must be sealed with an approved system to prevent the interior spread of fire.
Cavity barrier performance has to be the same or better than the performance of the barrier they’re installed above. They are not the same as fire barriers. Instead, they are designed to reduce the spread of fire and smoke in the ceiling void, which means they do not work for maintaining compartmentation. Fire barriers actually provide compartmentation in the ceiling and roof voids as long as the system is as good as or better than the specified fire rating of the structure below it. Also as long as they are tested and certified as safe and suitable to be used together.
