Abstract
A composite framing member especially suited for use as a stile in a stile and rail door or window assembly. The framing member includes a hollow member, preferably manufactured from a fiberglass reinforced plastic. The hollow member is overlayed with two wood edge inserts and two wood overlays to give the appearance of a solid wood door or window assembly. The edge inserts include surfaces which are coplanar with the longitudinal surfaces of the hollow member, and the overlays are affixed to both the longitudinal surfaces and the coplanar surfaces of the edge inserts to provide added strength at glue lines. The composite framing member further provides a passage within which a locking mechanism may be disposed, yet not visible or accessible, which gives added security.
