I have a surgery center going in a PEMB. There is a 1-hour sepeartion wall (UL419) with no good details. Our architect has not been able to satisfy the fire marshall for the head of wall condition. The state wants the cut sheets and the details on site for the 80% inspection. The problem is, we need to leave the vapor barrier and insulation in place to avoid condensation and mold happeing in the wall. The drywall company hung the sheetrock tight to the deck and wants to just fire-caulk the joint. The fire marshall says he cannot attest to the system because it's about a 20 year old building and we don't know the flame spread on the vinyl face. Surely there is some information about this as these buildings have been around for a long time now. I don't know how to satisfy all parties.
Hello,
I've attached a few systems that I believe may meet your needs based on the conditions. If these will not work for you, we will need to create an Engineering Judgement (EJ) for you. I've included information on where you can submit a request below.
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.
