Hello.
Can Hilti Firestop products be used over / on top of existing firestopping materials from other manufacturers?
Thank you
Hi Jake - this will be addressed on a case-by-case basis. For specific applications, please submit a Question request through our online platform, HCP. We will need the PDS and SDS for any products that will be coming into contact with our firestop products, along with a detailed description of how the products will be installed and interface.
Hilti is proud to announce the launch of our engineering website, the HILTI CONSTRUCTION PLATFORM (HCP). This platform will be the home for all of your Fire Protection Engineering needs, including Engineering Judgment requests. You can find more information on how to access this new platform here: https://www.hilti.com/ej (US) or https://www.hilti.ca/ej (Canada.)
