Is there a UL-listed firestop detail, or the closest applicable system, for an HSS beam penetrating a 1- or 2-hour rated gypsum wall where the beam is not fireproofed? If not, can you provide an Engineering Judgment (EJ) for this condition?
Hi Rich, unfortunately we do not have any UL listed systems with HSS in a gypsum wall. We have an HSS in a gypsum shaft wall (W-L-7321) and a W beam in a gypsum wall (W-L-7188) but we do not have an HSS beam in a gypsum wall. We can provide you the solution in an Engineering Judgement (EJ). Please see below on how to submit for an EJ.
Thank you,
Chase Hellan
Sr. Fire Protection Engineer
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.
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.
