Wes,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs. It sounds like you have several different applications. For your stud framed exterior wall, I would suggest looking at something like HI/BP 120-03. For your other two conditions, we have multiple systems that could work, so I would suggest looking at the Firestop Selector to find an application that works for your needs. If there is not a system that works for you, then 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 and the Hilti Firestop Selector. You can find more information on how to access this new platform here: https://www.hilti.com/ej (US) or https://www.hilti.ca/ej (Canada.)
Along with HCP, Hilti is excited to announce our new mobile app for all your firestop needs: Hilti Firestop Selector. Using the Firestop Selector app gives you easy access to the Hilti Fire Protection Design Team from the jobsite, on the road, or in the office to request a new EJ, an EJ Revision, or ask a Question anytime, anywhere. You can download the app using the Google Play Store or Apple App Store.
If you have any questions, please reach out to our customer service team at 1-800-879-8000 (US) or 1-800-363-4458 (Canada) for assistance.
Thank you,
Jessica Starks
