I'm looking for a 1 hour UL listed fire barrier for an exterior aluminum curtainwall at spandrel glazing and at metal panel. 5/8" Type X drywall and framing would be located at the interior to achieve the rating. In my search, I could find many examples of horizontal perimeter fire barrier systems at the wall/floor intersection. However, I'm looking for a 1 Hour UL listed vertical fire barrier because the building is close to a property line. Is there a UL rated assembly as shown in the uploaded details and as described above?
Hello,
Thanks for using the AskHilti platform. Hilti does not manufacture any fire-rated exterior curtain walls. Some manufacturer's we've worked with in the past who have fire-rated curtain walls are Technical Glass Products and Aluflam. They would be a better start for a something like this.
If you are looking for UL/Intertek Approved Perimeter Joint Systems, we have several that would work in order to help you comply with requirements outlined in IBC Section 715.4. We can also look at providing customized details for your conditions.
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.
