1 hour fire-rated ceiling for basement is basically, 2 5/8's drywall doubled up. Also anything protruding or flow-throughs need to be caulked with fire rated caulking. Make sure that when you hang the first sheet of drywall that you take, mud and then put the other piece up. That is what makes it 1 hour.
