Hello Percy,
Thank you for using ASK Hilti!
If you're looking to use a gypsum patch for this opening we will not be able to provide guidance as that's not firestop and we would recommend reaching out to the gypsum manufacture instead. However, if you're looking to firestop this opening we can review this application for an Engineering Judgment (EJ) to accommodate the firestop application described in your inquiry. EJ's are custom details showing the exact application with the firestop components required to maintain the stated ratings.
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: https://www.hilti.com/ej (US) or https://www.hilti.ca/ej (Canada.)For instructions on how to register along with how to navigate the new platform, please see the attached document.
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.)Thank you for choosing Hilti as your firestop experts!
