To all: I am doing a Project 4 Story Residential building witch is designed per NFPA 13 and it is being built with Type V Construction. The Stairs are being sheet rock w/ 1 layer of 5/8" GWB underneath all landings, and all walls in the stair. It does state in NFPA 13 8.14.3, Combustible Construction. Sprinklers shall be installed beneath all stairway of combustible construction. (1) Does putting 5/8" GYB Sheet rock underneath the landing makes this a Non combustible stair? (2) If this is considered a combustible stair do we have to put sprinklers underneath all landings, not just underneath the entry on each floor, including underneath the intermediate landing between the floors
