ABSTRACT:
Plastic shutters and the like are manufactured by attaching a decorative plastic shroud to a supporting frame without substantial use of adhesives by a process in which a generally pan-shaped rectangular shroud is heat formed, the supporting frame is positioned within the plastic shroud, and the sides of the plastic shroud are post-formed to embrace the outer rim of the supporting frame. Since the supporting frame and the plastic shroud are not completely bonded to each other, the shroud and the frame can separately expand or contract without materially warping or distorting the shroud.
