(1) the presence of the gypsum board does not change the construction to non-combustible.
(2) good question, that one is not clear to me. My initial response would be "yes", but the requirement is vague. Paul J. Pinigis, P.E.

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 Thanks Shawn Fenneran CET#105218 _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field)
