Is there a UL listed firestop detail for duct and conduit penetrations at a 1hr rated horizonal shaft wall condition?
Hello!
I wanted to let you know we don't have an exact system to address this application. We however 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. If you would like to get an engineering judgment, please follow the information below for submitting a request.
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.
