Greetings Yousef! Thank you for checking out ASK Hilti! You would need to refer to the project plans or AHJ to determine if the intersecting wall are rated. Then you would need to determine which product was installed within the joint. If the product cannot be determined, then you may need to take the existing product out and install a listed UL/cUL firestop system.
You can browse available UL/cUL listed firestop systems via the HCP by following the link below:

If you have any questions, please reach out to our customer service team at 1-800-879-8000 (US) or 1-800-363-4458 (Canada) for assistance.
Thank You for choosing Hilti as your Firestop Experts!
