We have a military project (UFC 3-600-01 and NFPA 101 criteria) with 1/2-hour fire-resistance-rated fire barriers between each sleeping unit.
Each 1/2-hour wall consists of gypsum on each side of a metal-studded wall. The gypsum runs within about an inch of the floor in each room (not touching the floor, intentionally, to avoid soaking up moisture/water) where it has metal stud on the backside.
Is firestop required along the base of the gypsum to maintain the 1/2-hour rating?
