Patent number: 11976465Abstract: Disclosed herein are plaster boards having a first surface and an opposing second surface, and a first edge and an opposing second edge that bound the first surface and the second surface. The first surface includes a first section and a second section, the first section being raised compared to the second section, the second section abutting the second edge. The second surface includes a first section and a second section that are separated by a boundary between the first edge and the second edge. The first section of the second surface is substantially parallel to the first section of the first surface. The second section of the second surface slopes toward the first surface from the boundary toward the second edge. Methods for making the plaster boards involve forming wet plaster material and drying the wet plaster material such that the wet plaster material hardens into a plasterboard.Type: GrantFiled: January 3, 2022Date of Patent: May 7, 2024Assignee: CertainTeed Gypsum, Inc.Inventors: John Bridenstine, Christopher G. Riley, James Dimitrakopoulos

Patent number: 11655635Abstract: Disclosed herein are plaster boards that include first and second layers of hardened plaster material, a liner attached to the first layer of hardened plaster material, and a first material (e.g., a polymer material such as a viscoelastic polymer) adhered between the liner and the second layer of hardened plaster material. The liner includes one or more structurally weakened regions each extending substantially from a first edge to a second opposing edge of the plaster board. The structurally weakened regions of the liner may facilitate creation of a fissure that propagates substantially within a plane within the plaster board. Methods for making the plaster boards may involve drying wet plaster material while it is in contact with a liner having structurally weakened regions, processing a liner to form its structurally weakened regions while in contact with wet plaster material, or processing a liner to form its structurally weakened regions while in contact with hardened plaster material.Type: GrantFiled: May 4, 2021Date of Patent: May 23, 2023Assignee: CertainTeed Gypsum, Inc.Inventors: James Dimitrakopoulos, Vincent Infante, John Bridenstine, David William Pugh, David Hagelgans, Ying Wang, Xuejuan Xu

Publication number: 20220074197Abstract: One aspect of the disclosure is a plaster board having a first edge and an opposed second edge, and a third edge and an opposed fourth edge. The plaster board includes a first layer of hardened plaster material including a first surface and an opposed second surface, and a second layer of hardened plaster material including a first surface and an opposed second surface. The second layer of hardened plaster material is stacked against the first layer such that their first surfaces face one another. The first layer and the second layer together define the first, second, third, and fourth edges of the plaster board. The plaster board also includes a viscoelastic polymer disposed between the first surfaces of the first and second layers of hardened plaster material. The viscoelastic polymer does not extend substantially to the first, second, third, and fourth edges of the plaster board.Type: ApplicationFiled: November 16, 2021Publication date: March 10, 2022Inventors: James Dimitrakopoulos, Gregory F.
