Flanking paths associated with exposed roof decks in condominiums.
View through CrossRef
An award winning residential/commercial condominium project featured two-story loft condominiums with an industrial look. The building was constructed with steel structure, exposed concrete on metal deck floors, and an exposed metal deck roof. Condominiums were separated by gypsum board on metal stud walls. A number of owners in the building complained of poor sound isolation from adjacent units. Field tests showed that sound isolation of the walls fell below expectations for the design. Subsequent investigation showed that a variety of structureborne and airborne flanking paths contributed to poor sound isolation. Improving sound isolation required a combination of conventional and creative methods.
