About this detail

An acoustically lined thru-wall sheet metal transfer duct penetrates an acoustically rated partition with dimensions of 22 inches, 46 inches, or 70 inches as sized per plans. The duct features a 1-inch, number-two density insulation lining and is configured with an offset length to avoid line of sight. Acoustic sealant is applied on both sides around the structural deck and the duct opening. The surrounding partition consists of a gypsum wallboard ceiling, scheduled flooring and base, and a full-height sound attenuation blanket.
