Patent number: 11661790Abstract: A door includes a first skin, a second skin, two stiles, a core, and a gas permeable membrane. The first skin provides a first outer door surface. The second skin provides a second outer door surface. The two stiles are disposed at least partially between the first skin and the second skin. At least one stile defines a vent therein. The core comprises a foam material and is disposed between the first skin and the second skin. The gas permeable membrane, which is permeable to gas but not to the precursors of a foam material, is disposed on the at least one stile covering the vent. The gas permeable membrane contacts the foam material in the core, and separate the foam material in the core from the vent.Type: GrantFiled: May 27, 2022Date of Patent: May 30, 2023Assignee: PLASTPRO 2000, INC.Inventors: Scott Evert Johnson, Shirley Wang, Jared Andrew Garrett

Publication number: 20190211616Abstract: A method for making a door skin or making a door is provided. A wood board is first provided. The wood board comprises a surface having a first texture with a first plurality of grains, and at least one knot, which has a predetermined depth of crack. The surface of the wood board is scanned to obtain a first profile of the first texture. The first profile of the first texture is modified to provide a second profile of the second texture, which includes a second plurality of grains and the at least one knot. A mold comprising a metal surface is formed based on the second profile of the second texture.
