Schematic only. These drawings show common joint types in general terms. They are not a specific tested system, and they carry no rating, product or approval. The sealant, depth, backing and installation for any given project are set by that project’s specified building system and documentation.

Each project has different requirements, so fire rated caulking should be completed according to the specified building system, product requirements and project documentation.
