Don I have a GC client that’s asking me a question that I cannot answer.
For a 1 hour / non load bearing masonry wall that would be between two floors, do you need to have any special caulking (fire or other) at the top on the masonry wall, besides the mortar joint.
This is new to me so let me know your opinion on this.
As long a there is a full mortar joint the face shell thickness on both sides of the wall there should be no question about the overall fire rating of the wall. Consider that the entire wall is FILLED with joints filled with mortar the face shell thickness of the wall. The joint at the top of the wall would be no different.
