Firestopping systems for hollow core concrete blocks
Hello, I'd like to make sure I understand this correctly. If a system states "Wall may also be constructed of any UL Classified Concrete Blocks*." Does it include UL Classified Hollow Concrete Blocks? I would assume so but then some systems specifically mentions the hollow core ones.

Hi,
Apologies for the delay in response, the reply had not posted earlier.
Kindly send the system you are referring to and more details about the walls you have and the application to cafirestop@hilti.com so we can assist you with this inquiry.
