OK. Need a little help here. Frustration at dangerous level and rising..
Many times in the past I have drawn/specified and had approved the following as a 1hr. fire rated wall.
5/8X gyp.bd.int. finish, 2x4 studs 16"o.c., db. top pl., sgl. bot. pl., 3&1/2 FG batts, 1/2" osb/ply'd sheathing with 3&5/8" thk. brick veneer ext. finish.
Now the new plan checker wants me to indicate a specific assembly listed in the IRC table 720.1 or a UL approved assembly. for a one hour wall.
There are dozens in the IRC but none exactly like this and only about a gadzillon UL listed assemblies that would take days to search through.
Anyone have any idea where I might get this information. Thanks
