Abstract: A door skin comprises an exterior side and an interior side for being secured to a frame member. First and second molded, spaced stiles lie on a first plane. A flat planar portion is disposed between the stiles and lies on a second plane spaced from the first plane. A first interface portion is disposed between and contiguous with the stiles and the flat planar portion. First and second integrally molded, spaced rails lie on a third plane, wherein the third plane is intermediate the first and second planes.

Abstract: A composite building component includes a non-planar molded composite web having two outer zones and two angled zones wherein the caliper of the angled zones differs from the caliper of at least one of the outer zones, and a flange disposed on an outer surface of an outer zone. A method of providing a composite building component also is disclosed.

Abstract: A universal door skin blank comprises an exterior side and an interior side for securing to a frame member, first and second molded, spaced stiles, and a flat planar portion disposed between the stiles and lying on a plane spaced from the plane of the stiles. An interface portion is disposed between and contiguous with the stiles and the flat planar portion. The invention also relates to a door having at least one universal door skin blank, with at least two separately formed rails secured to the planar portion of the blank at opposite ends thereof.
