Thank you, Bob Knight, CET III 208-318-3057 From: Sprinklerforum [mailto:[email protected]] On Behalf Of Rocci Cetani 3 Sent: Monday, July 31, 2017 2:57 PM To: [email protected] Subject: non combustible/limited combustible space We have a hotel we are working on and we have limited space in the corridors (surprise surprise) so I am trying to not sprinkle the concealed space in the corridor. Situation is a concrete deck with min. ½” plywood sheathing below it followed by 2x8 wood joists with (2) layers of 5/8” type X gyp. The ceiling below is 1 5/8” metal joists with 1 layer of 5/8” type X gyp , attached directly to ceiling joists. ( We have roughly 12” from bottom of (2) layers of gyp to top of ceiling framing.) Because the 2x8 are covered with 2 layers of 5/8” gyp can I consider this space non/limited combustible per 8.15.1.2.2? (BTW the architect is calling this out as a 1 hour rated assembly.)
