About this detail

These architectural details illustrate various rated metal stud wall assemblies with differing STC ratings and fire resistance periods up to two hours. The drawings show head conditions running both parallel and perpendicular to the floor deck, incorporating standard UL joint systems such as UL HW-D-0633 and UL HW-D-0060 with one-inch vertical deflection. Wall configurations feature cold-formed steel studs, acoustical insulation, and specific layers of gypsum board based on the required STC ratings of 48, 52, or 64. Base and plan conditions indicate typical partition anchoring and fireproofing integration where rated floors occur.
