Top of Wall Firestopping
Can you provide a detail and UL (or other agency) design for firestopping at the joint between top of 2 hour rated CMU fire wall and the underside of a non-rated metal roof deck? (Fire wall may stop at underside of deck per 2015 IBC 706.6, Exception 2.)

I posted this question 10 days ago and haven't received a response from Hilti. I suggest that anyone looking for an answer not look for it here.

Thanks Russell. I submitted for an Engineering Judgement yesterday after calling Hilti directly. Still no response from them on this chat.

Have you tried submitting an Engineering Judgement request? After I posted my comment here I went there and filled out the form and they responded within a couple of days with a design tailored for my particular variation of being accessible from one side. Perhaps give that a try.

I have the same situation and am looking for an answer.
