Does your project have horizontal rated lids? I’m not talking about rated ceilings that are part of floor ceiling assemblies. I’m talking about a rated ceiling where the entire rating comes from a gypsum assembly.
If you have one, did you know that there are no systems for anything other than the ceiling.
There are no listed systems for access panels.
There are no listed systems for firestopping penetrations through these fire rated ceilings.
There are no listed systems for control joints in these assemblies.
If you are designing with these assemblies, please be aware of this.
If you are building these assemblies, please ask questions before you start.
