I am searching for a 1HR fire rated head of wall detail with a UL number.
The wall assembly is 6" metal stud framing with 5/8" type 'x' gypsum board each side of wall, 1HR fire rated wall assembly. The top of wall will be attached to the underside of existing non-rated 2"x6" wood roof joists (24" O.C.), which run perpendicular to the new 1HR fire rated wall assembly. Please refer to the attached detail for your reference.
Hello Please submit an Engineering Judgment request (EJ) - see below on how to submit. As an FYI with the wood joists there is a high likelihood we will not be able to provide a rated solution here.
Thank you,
Chase Hellan

We are proud to announce the launch of the HILTI CONSTRUCTION PLATFORM (HCP), our company’s new engineering service website. This platform will be the home for all of your Fire Protection Design needs. Instead of emailing a PDF form for a request, the platform enables you to create new Engineering Judgment (EJ) requests, submit revisions to previously completed EJs or connect with an FPE on a question. HCP also enables you to track the status of your request.
You can find more information on how to access this new platform here: http://www.hilti.com/ej (US) or http://www.hilti.ca/ej (Canada.) If you have any questions or require assistance navigating the platform, please call Customer Service for help at 1-800-879-8000 (US) or 1-800-363-4458 (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 a Question anytime, anywhere. You can download the app using the appropriate link below.
