A metal stud partition terminates at a concrete-filled metal deck with firestop systems. The assembly incorporates a slotted top track supporting type 3 insulation and spray-applied fire stopping. The perpendicular and parallel metal deck configurations correspond to Underwriters Laboratories design numbers HW-D-0569 and HW-D-0570 respectively. Clearances include three-quarters of an inch typically with a one-and-a-half inch maximum spacing.
