Abstract: In accordance with at least one aspect of this disclosure, a door comprises a frame comprised of two horizonal rail portions and two vertical stile portions. At least one of the vertical stile portions includes a first ply formed of a first material, a second ply formed of a second material that is different from the first material, and a third ply formed of the first material, the three plies forming a layered stack. A stack direction of the layered stack is such that the first ply defines an outer peripheral surface of the frame, the third ply defines an inner peripheral surface of the frame, and the second ply is sandwiched between the first ply and the second ply. The second material is configured to prevent warping of the frame and configured to provide repeated positive engagement for a fastener installed through the frame.
