We are looking to obtain a 1.5 hour fire rating around large ICI duct work that penetrants though a block wall. The problem is our gaps are larger then we exspected. Do you have a product to help ?
Hi Terry - without knowing the specific parameters for your condition, it would be hard to give you guidance on whether we have a listed system that would work here. My first recommendation would be to check out the firestop system selector through our online platform, Hilti Construction Platform (HCP). If a system doesn't exist for your condition from there, I would request an Engineering Judgment through HCP.
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: hilti.com/ej (US) or hilti.ca/ej (Canada.)
Hope this helps point you in the right direction.
Regards,
Nate Crawford - Lead FPE
