We are using Firestop Top Track Seal CFS-TTS system in a 1 hour rated drywall, a metal conduit runs through the wall right below the track seal that has been fire caulked. The fire caulk is touching the top track seal. Can the same brand, but two different systems touch each other? picture shows a black pvc coated conduit below top track seal with fire caulk touching the track seal.
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 showing a penetration through the joint with a top track seal; however, 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.
Hilti is proud to announce the launch of our engineering website, the HILTI CONSTRUCTION PLATFORM (HCP). This platform will be the home for all of your Fire Protection Engineering needs, including Engineering Judgment requests.
