can firecaulk be covered by SFRM ?

Raphael,
 
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs.
 
We will need more information before we can provide you a definitive answer on this, so I would recommend sending over an Engineering Question.
 
Hilti is proud to announce the launch of our engineering website, the HILTI CONSTRUCTION PLATFORM (HCP).
