ABSTRACT:
A unitary composite frame member of two or more structural elements. A first and a second of the elements each contributes strength to the member. The second element which is preferably a plastic, has a conductivity not exceeding 5% of that of the first element, and covers the first element, contributing to the shape of the frame member. Preferably each of the two elements is strong enough to retain its shape without aid from the other element, and the second element contributes at least 10% of the structural strength of the member. The elements are molded together, with the covering element in a plurality of similarly shaped openings in the element that it covers.
