Looking at the termination of corridor walls and non-rated partitions at a 1 hour floor/ceiling above.
IBC 2015 Section 714.4.2, Exception 7, states:
The ceiling membrane of 1- and 2-hour fire resistance-rated horizontal assemblies is permitted to be interrupted with the double wood top plate of a wall assembly that is sheathed with Type X gypsum wallboard, provided that all penetrating items through the double top plates are protected in accordance with Section 714.4.1.1 or 714.4.1.2 and the ceiling membrane is tight to the top plates.
It appears this exception "went away" or may have been relocated in the 2018 IBC. Can someone give me some direction?
Thanks in advance.
