I've seen a few posts regarding firestopping the top of a wall from one side but they pertain to shaft walls. Do you have a system to firestop a 1 hour rated metal stud wall from one side? We are trying to assure firestopping at the top of wall but one side is not feasibly accessible due to existing steel framing. Top of wall is against metal decking with concrete poured over it. Conditions are both perpendicular and parallel to deck flutes. Thank you for any information you can share! Tim
Hello Timothy,
We have system HW-D-0388 that may work for you. If not, you would need to submit for an engineering judgement request as we do not have any other systems for the top of a gypsum wall from one side only. Please use the link below to start the engineering judgement process.
