About this detail

This suspended gypsum board ceiling and soffit detail features a dropped framing layout supported by overhead steel framing or a concrete slab. Three-and-five-eighths-inch by twenty-gauge steel studs spaced at sixteen inches on center form the vertical soffit framing with a maximum height of eight feet, braced by diagonal studs at thirty to forty-five degrees spaced at forty-eight inches on center maximum. One-and-a-half-inch carrying channels spaced at forty-eight inches on center maximum suspend the ceiling grid, which uses seven-eighths-inch furring channels spaced at twenty-four inches on center maximum. The ceiling and soffit planes are finished with one-half-inch gypsum board typically unless noted otherwise, complete with a corner bead at the exterior soffit edge.
