Per NFPA 101

3.3.254* Smoke Partition. A continuous membrane that is designed to form a barrier to limit the transfer of smoke.

A.3.3.254 Smoke Partition. A smoke partition is not required to have a fire resistance rating.


3.3.31.2* Smoke Barrier. A continuous membrane, or a membrane with discontinuities created by protected openings, where such membrane is designed and constructed to restrict the movement of smoke.

A.3.3.31.2 Smoke Barrier. A smoke barrier might be vertically or horizontally aligned, such as a wall, floor, or ceiling assembly. A smoke barrier might or might not have a fire resistance rating. Application of smoke barrier criteria where required elsewhere in the Code should be in accordance with Section 8.3.

I hope this help
