Abstract
This composite building stud combines two metal shapes, inner and outer, with an insulating material to form a composite structural member having 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. The shapes, inner and outer, with an insulating material form a composite structural member that has an interlocking shape which holds the insulating material in compression and mechanically couples the inner and outer members.
