ABSTRACT:
The specification discloses metallic structural channel members for building construction which are characterized by low thermal conductivity and low sound transmission. The channel members have two end panels connected by a side panel. The side panel has a plurality of rows of strips, severed from the side panel along two coextensive parallel slits and stretched out of the plane of the panel. The rows of strips are displaced variously all to one side or all to the other, or part to one side and part to the other of the side panel. The end panels are also provided with severed strips, somewhat wider than the strips on the side panel, for mounting wall board or metal lath elements.
