This paper extends previous studies on the sound transmission through single-skin profiled metal cladding systems to cover realistic double-skin cladding constructions. A method for predicting the sound reduction of such double-skin cladding systems is developed which takes proper account of the orthotropic nature of the cladding sheets, the sound bridging through fixing supports, and the transmission loss through the in-fill insulation. The method is verified against sound reduction measurements made on a variety of commercial cladding products which cover a good range of basic double-skin cladding construction types. Good agreement between prediction and measurement is found.
