We have existing interior walls that extend above the suspended ceilings. The studs extend to the deck but the substrate does not. Looking for a 1 hour system that can be inside the wall at the ceiling level. I attached a detail of what were looking for and picture of existing condition.
Hello,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs.
We do not have a listed system that matches this condition but we can address your application through an Engineering Judgment which will be a custom detail showing your exact application with the firestop components required to maintain the stated ratings. Make sure to specify if this is a "fire barrier" or "fire partition".
To officially submit for Engineering Judgment please go to www.hilti.com/ej

Ricardo Mejia
