NYC Building Code 2014 > 7 Fire and Smoke Protection Features > 721 Calculated Fire Resistance > 721.3 Concrete Masonry > 721.3.2 Concrete Masonry Walls > 721.3.2.2 Finish on Fire-Exposed Side
JUMP TO FULL CODE CHAPTER
Where plaster or gypsum wallboard is applied to the fire-exposed side of the wall, the contribution of the finish to the total fire-resistance rating shall be determined as follows: The time assigned to the finish as established by Table 721.2.1.4(2) shall be added to the fire-resistance rating determined in Section 721.3.2 for the masonry alone, or in Section 721.3.2.1 for the masonry and finish on the nonfire-exposed side.
