I had a question today about whether a one hour rated wall requires the door frame to be grouted. I was given the UL number A-1924 as well as UL 10C U8C7-2(1997)
Any help in either the direction I could approach this or an all out answer would be appreciated.
I did call UL's architectural services people who told me that it should be listed in the installation instructions or is up to the AHJ. :roll:
