Hello, I am looking for ULC details for 8" XFR PVC pipes that penetrate (a) 1-hr. drywall & metal stud wall; (b) 4" thick concrete slab; and (c) OWSJ floor, with 2" concrete topping on metal deck and 5/8" fire-rated drywall on the underside of joists.
Thank you in advance for your assistance!
Jason,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs. At this time, the only listed system we have for an 8" XFR-PVC is cUL CAJ2831 (attached).
As such, we can address your applications through Engineering Judgments, which will be custom details showing your exact applications with the firestop components required to maintain the stated ratings.
