21 THERMALLY INSULATAED COMPOSITE FRAME MEMBER AND METHOD FOR MANUFACTURE Abstract of the Disclosure A thermally broken composite frame member, including, irnner and outer elongated metal elements in parallel spaced apart relation interconnected by a connector of rigid insulating material. The frame member includes a mechanical interlock between the metal elements and the connector which prevents the metal elements from becoming laterally or longitudinally displaced with respect to the connector in response to tensile or shearing forces. Thus, the structural integrity of the frame member is not solely dependent on the adhesion between the insulating material and the metal elements, and insulating materials which do not adhere to metal to any appreciable degree may be employed.
