I need some facts or opinions. Mine doesn't seem to count any longer. I have 2x9 solid wood floor joist (150 year old historical building) that I'm attaching gypsum board to the bottom in order to eliminate having to sprinkler a concealed combustible space. The architect is asking me if the gypsum board needs a fire rating and do the joints need to be mudded. I say yes to both but he needs more than my opinion.
Can you help, please?
