ABSTRACT:
To provide a frame with members having two outer elements which are interconnected by an insulator, each member is formed from a hollow bar in which the insulator is molded and then two longitudinal strips are removed from the bar, the two remaining parts of the bar forming the outer elements of the frame member. The bar is provided with longitudinal weakening grooves to facilitate removal of the strips, or the strips constitute mold members which clamp the outer elements and, together with the outer elements, define the hollow cavity within the bar.
