Which firestop is suitable for sealing joint between facade curtain wall and edge of slab with joint widht 15 inches
Hello Hadi,
Thank you for your question. Please note that there is no UL or Intertek listed system that allows for a 15" joint width. Depending on the current design, the Hilti Fire Protection Design Team should be able to accommodate a 15" joint at the edge of slab in an Engineering Judgement (EJ), or a custom, project specific firestop design. To request an EJ, please submit a request through the Hilti Construction Platform by visiting https://www.hilti.com/ej (US) or https://www.hilti.ca/ej (Canada). Note that if this is your first time requesting an EJ, you will need to create an account. If you need any assistance registering or navigating the platform, please reach out to our customer service team at 1-800-879-8000 (US) or 1-800-363-4458 (Canada).
Please let me know if you have any additional questions.
Thank you,
Michael Duncan
Fire Protection Engineer
