Do you have a 2 hour head of wall detail for PEMB

Hi Bob,
Hilti has a few details that may work in your application. UL system CJ-D-0004 is a two hour gypsum wall to bottom of a non fire rated horizontal (steel) assembly in the perpendicular configuration. If you have this in a parallel configuration then you would need an engineering judgement (EJ). Below is how to submit an EJ along with why they are required.

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.

_________________________

Because of the numerous field conditions encountered, it is not always possible to identify a firestop system that has been tested / classified by a nationally recognized independent testing laboratory (such as Underwriters Laboratories, Underwriters Laboratories of Canada, Factory Mutual, Intertek/Omega Point, etc.). In such a case, an Engineering Judgment (“EJ”) or Firestop Custom Detail (“FCD”) may be appropriate. An EJ/FCD represents a firestop solution that would be expected to pass the stated ratings and requirements if tested.

All Hilti EJ’s/FCD’s are designed in accordance with the International Firestop Council (“IFC”) guidelines. These EJ’s/FCD’s are designed by our experienced degreed fire protection technicians using, as the basis for our opinion:
• relevant 3rd-party testing in accordance with ASTM E-84, ASTM E-119, ASTM E-136, ASTM E-814, ASTM E-1966, ASTM E-2307, CAN/ULC-S115-11, UL 263, UL 723, UL 1479, UL 2079, or ASTM E-2837 • wide-ranging related internal testing of our firestop products, and • extensive knowledge and experience of the performance characteristics of Hilti firestop products, and firestopping technology generally.
Pursuant to IFC guidelines, each EJ/FCD is intended for one specific jobsite, since even slight variances from one application to the next can affect system performance.
