Sorry if this has been addressed in a previous thread; I did a search but didn't find anything. We use the 2009 IBC.
Table 601 requires 1 hr protection for primary structural frame, interior and exterior bearing walls, floor construction and secondary members, and roof construction and secondary members.
Assuming the use of 5/8 Type X gypsum for fire rating:
So will a second story floor have 5/8 Type X on the bottom and the top of the floor joists? Also, will the ceiling/roof assembly have 5/8 Type X on the bottom and top of the rafters? Basically every structural member is wrapped in 5/8 Type X gypsum.
Thanks in advance.
