I have an existing penetration going through a non-rated floor that is transition from non-fire rated to a 2-hour rating. What provisions do I need to take to upfit the existing conduit penetration to also be 2-hour rated?
Hi Eric,
Thank you for your question. We do not have an off the shelf listed system for you to utilize for your application. The firestopping solution will depend on how the assembly is being built up from non-fire rated to be fire-rated and other variables. Therefore, we will need to review your application for an Engineering Judgment (EJ) to accommodate the firestop application you described in your inquiry. EJ's are custom details showing your 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.)
