Abstract

A plurality of stacked door skins is provided, the plurality including at least first and second door skins each including at least one inner panel, an outer body portion surrounding the at least one inner panel, and at least one contoured portion surrounding the at least one panel and interconnecting the at least one panel to the outer body portion. The at least one contoured portion includes a substantially V-shaped indent area adjacent to and within the outer body portion, a planar area that is substantially parallel to the outer body portion and is adjacent to and within the substantially V-shaped indent area, and a declining area adjacent to and within the planar area and terminating at the inner panel.

3. The stack of door skins of claim 1 , wherein the first inner panel is continuous and flat and positioned centermost relative to the first contoured portion, and wherein the second inner panel is continuous and flat and positioned centermost relative to the second contoured portion.

4. The stack of door skins of claim 1 , wherein the first and second door skins comprise a wood composite composition.

5. The stack of door skins of claim 1 , wherein the first and second door skins comprise a fiberglass-reinforced polymer.

6. The stack of door skins of claim 1 , wherein the at least one first contoured portion is formed as a unitary piece with the at least one inner first panel and the first outer body portion, and wherein the at least one second contoured portion is formed as a unitary piece with the at least one inner second panel and the second outer body portion.

7. A stack of door skins, comprising:

a first door skin comprising

a first outer body portion;

at least one first inner panel extending between and terminating at a first continuous planar outer perimeter, an entirety of the first inner panel within the first continuous planar outer perimeter being parallel to and recessed from the first outer body portion, the first inner panel being recessed from the first outer body portion in a first declining direction; and

at least one first contoured portion surrounding the at least one first inner panel and interconnecting the at least one first inner panel to the first outer body portion, the at least one first contoured portion comprising

a first V-shaped indent area surrounded by the first outer body portion,

a first planar area that is parallel to the first outer body portion, and is surrounded by the first V-shaped indent area, and

a first declining area sloped in the first declining direction surrounded by the first planar area and terminating at the first continuous planar outer perimeter of the first inner panel; and

a second door skin with an identical profile to and stacked on the first door skin, the second door skin comprising

a second outer body portion spaced from the first outer body portion;

at least one second inner panel extending between and terminating at a second continuous planar outer perimeter, an entirety of the second inner panel within the second continuous planar outer perimeter being parallel to and recessed from the second outer body portion, the second inner panel being recessed from the second outer body portion in a second declining direction, the second inner panel being spaced from the first inner panel; and

at least one second contoured portion surrounding the at least one second inner panel and interconnecting the at least one second inner panel to the second outer body portion, the at least one second contoured portion comprising

a second V-shaped indent area surrounded by the second outer body portion, the second V-shaped indent area nesting in contact with the first V-shaped indent area;

a second planar area that is parallel to the second outer body portion, and surrounded by the second V-shaped indent area, the second planar area being spaced from the first planar area, and

a second declining area sloped in the second declining direction surrounded by the second planar area and terminating at the second continuous planar outer perimeter of the second inner panel, the second declining area nesting in contact with the first declining area.

8. The stack of door skins of claim 7 , wherein the first planar area is coplanar with the first outer body portion, and the second planar area is coplanar with the second outer body portion.

9. The stack of door skins of claim 7 , wherein the first inner panel is continuous and flat and positioned centermost relative to the first contoured portion, and wherein the second inner panel is continuous and flat and positioned centermost relative to the second contoured portion.

10. The stack of door skins of claim 7 , wherein the first and second door skins comprise a wood composite composition.

11. The stack of door skins of claim 7 , wherein the first and second door skins comprise a fiberglass-reinforced polymer.

12. The stack of door skins of claim 7 , wherein the at least one first contoured portion is formed as a unitary piece with the at least one inner first panel and the first outer body portion, and wherein the at least one second contoured portion is formed as a unitary piece with the at least one inner second panel and the second outer body portion.

13. A stack of door skins, comprising:
