Abstract
This composite building stud combines two metal shapes, inner and outer, with an insulating material to form a composite structural member having excellent acoustical properties. The stud also has an insulating valve (R-value) greater than a similar metal member normally used as a stud in a residential structure. The composite also has a strength comparable to that of a similar steel member normally used as a stud in a residential structure. One shape encompasses the other shape. The composite structural member eliminates any direct metal connections and thus eliminates any thermal shorts that reduce the overall insulating value (R-value) of the composite member.
