What UL recommended for penetration of Schedule 40 PVC drain waste vent through rated walls/floors. What would you recommend where the pipes are vertical through the bulkhead wall space but with a rating above and below in the floors and ceilings.
Hi Timothy we most likely will have systems for you however we would need to know more about your building and penetrations. We would need know the hourly rating, types of walls (and ceilings which sound like G500), size of penetrations, opening sizes, etc. If you want to submit the details to Hilti Construction Platform (below) we can help you out or get you in touch with the local FPS.
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.
