A chase partition assembly consists of two parallel rows of steel studs faced with five-eighths inch gypsum board on each exterior side. A sound attenuation blanket fills the cavity between the stud walls, which are connected by lateral bracing spaced across the variable chase width. Dimensions indicate five-eighths inch thick gypsum board, two and one-half inch steel studs, and a variable spacing in between as sized per plan. The assembly references UL design number U493 for fire rating compliance.
