Existing building, metal stud drywall partitions. We are trying to create a 1 hour rated horizontal separation at the ceiling level. Are there any products/details that depict how we can modify the existing partitions, at the ceiling locations, to create a continuous rating? We are trying to avoid having to remove all existing drywall and replace. We were hoping that there is some kind of rated infill that can be used at the partition cavities at the ceiling area.
Matthew,
Do you have a sketch or a detail of the application? Normally we don't infill the cavity to provide a rating. Our products need to be applied at the surface between rated assemblies based on UL 2079 guidance. A sketch or detail should help us to clarify if I am not understanding your question properly.
Regards,
Tyler Thomas
Tyler-
See attached sketch. I'm trying to figure out how to fire rate the shaded area of the existing partition.
We are trying to avoid having to remove/rebuild partitions, or add layers of drywall. I wasn't sure if there were any products (spray infills, batts/blocks, etc.) available that we could fill the partition void with and achieve a continuous rating at the ceiling level.
Hopefully this helps.
