About this detail

A metal runner track beds in a continuous bead of acoustical sealant directly on the floor slab. One side of the assembly receives two layers of 5/8-inch gypsum wallboard over RC-1 resilient channels spaced at 24 inches on center, while the opposite side receives one layer of 5/8-inch impact-resistant gypsum wallboard. Batt insulation fills the stud cavity between the layers. Acoustical sealant is applied to both sides at non-rated partitions, or firestop sealant is used at rated and smoke partitions.
