Abstract
An insulating composite frame member is disclosed which comprises an elongated gutter member and an elongated face member disposed in parallel, spaced apart relation. First and second facing flanges project toward one another from the gutter member and the face member respectively. A thermal isolator comprised of a thermally insulating material has first and second jaw-like clamps formed on opposite sides thereof which engage the first and second facing flanges respectively to secure the gutter member and the face member to the isolator. The frame member further includes means formed on the gutter member and the face member for crimping against the clamps of the isolator to lock the isolator to the gutter member and the face member. In the disclosed embodiment the isolator is adhesively bonded to the gutter member and to the frame member in addition to the mechanical coupling provided by the jaw-like clamps of the isolator. Also in the disclosed embodiment mutually engaging surfaces of each of the jaw-like clamps and their respective flanges are knurled to provide enhanced resistance to longitudinal shear forces.
