About this detail

This one-hour fire-rated partition assembly terminates at a concrete over metal deck ceiling above and a concrete deck or curb at the floor below. The head detail features a metal runner track matching the partition stud gauge, secured to the concrete deck with two powder-actuated Hilti X-U fasteners at twenty-four inches on center with a minimum one-and-one-quarter-inch embedment per ESR-2269. Continuous fire sealant is applied at both sides of the head joint for fire-rated conditions, and gypsum board is kept secure to studs below the deflection track. The wall cavity contains batt insulation between metal studs faced with a single layer of five-eighths-inch Type X gypsum board on each side. At the sill, a minimum twenty gauge continuous metal runner is anchored with powder-actuated Hilti X-U fasteners at sixteen inches on center with one-and-one-quarter-inch minimum embedment. Ceramic tile and base trim are installed where indicated by finish schedules.
