About this detail

A top-of-wall partition assembly intersects a concrete slab on metal deck with a slip track connection. Metal studs frame into a slotted slip track, secured at the center of the slot with number six screws to allow vertical deflection. A three-inch wide, twenty-gauge sheet metal strap fastens to the metal deck or slab with concrete screws at two feet on center. Minimum four pounds per cubic foot mineral wool packs the flutes, and open deck cell cavities receive safing insulation when the partition aligns with an open cell. Acoustical attenuation insulation fills the stud cavity, and a one-half-inch gap is maintained between the studs and the top track. A minimum one-sixteenth-inch sprayed fill material is applied with a minimum one-half-inch overlap onto the deck and gypsum board.
