Gypsum panels and methods for their manufacture are provided herein. The gypsum panels include a gypsum core having a first surface and a second opposed surface and a first fiberglass mat associated with the first surface of the gypsum core, such that gypsum from the gypsum core penetrates at least a portion of the first fiberglass mat.

Described herein is a drywall apparatus and method. The apparatus includes a finishing drywall liner, a framing drywall liner, a first gypsum-containing segment between the finishing drywall liner and the framing drywall liner, and a second gypsum-containing segment between the finishing drywall liner and the framing drywall liner. The first segment and the second segment are connected by a hinge formed from the finishing drywall liner and the framing drywall liner to allow an angle between the first segment and the second segment to vary.

A plasterboard comprising a gypsum matrix having wood particles embedded therein in an amount of at least 2 wt % relative to the gypsum, the gypsum matrix further comprising glass fibres in an amount of at least 1 wt % relative to the gypsum.

Disclosed is a composite gypsum board comprising a board core and a concentrated layer, as well as related methods of preparing board and slurries. The board core and the concentrated layer both are formed from water and stucco. The concentrated layer is designed to have higher density and/or nail pull than the core. The concentrated layer is further formed from a polysaccharide that forms a complex with calcium ions, e.g., an alginate compound such as sodium alginate. In some embodiments, the concentrated layer is formed from an enhancing additive to enhance strength therein, while the core is formed without using enhancing additive or less enhancing additive than used in forming the board core.

A plasterboard comprising a gypsum matrix having wood particles embedded therein in an amount of at least 2 wt % relative to the gypsum, the gypsum matrix further comprising glass fibres in an amount of at least 1 wt % relative to the gypsum.

A wall is made with the aid of drywall panels and a background. The drywall panels are provided with edge coupling profiles on their edges, which are arranged to be secured to the background and, subsequently, coupled to each other. The drywall panels may also be provided with a rear coupling profile. The drywall panels can be hooked together or coupled to each other by means of transverse sliding. The edge coupling profiles may also comprise anti-adhesive extensions, forming anti-adhesive edge areas at the front side of the drywall panel on which stucco mass does not adhere. The measures according to the invention are intended to provide drywall panels which, after use, can be disassembled easily and cleanly so that the drywall panels can be reused as drywall panels, resulting in that the environment is not burdened with gypsum waste caused by damaged, broken and destroyed drywall panels.

A corner drywall section has a drywall corner extending vertically from a floor to a ceiling. Further, the corner drywall section has a first wing extending a first side of the drywall corner at a first angle such that the first wing extends horizontally to a first stud, the first wing extending vertically from the floor to the ceiling and a second wing extending from a second side of the drywall corner at a second angle such that the second wing extends horizontally to a second stud, the second wing extending vertically from the floor to the ceiling, wherein the drywall corner, the first wing, and the second wing are a unitary piece of drywall.

The present invention is directed to a gypsum board and a method of making such gypsum board. In one embodiment, the gypsum board comprises a gypsum core including a first gypsum core layer and a second gypsum core layer sandwiching a laminate layer. The laminate layer comprises two outer laminate layers sandwiching an inner laminate layer, wherein the two outer laminate layers have a higher elastic modulus than the inner laminate layer. The method of making the gypsum board includes steps of providing facing materials and corresponding gypsum slurries wherein the laminate layer is provided in-line during the manufacturing process of the gypsum board.

A drywall system is provided including a first drywall panel and a second drywall panel connected to the first drywall panel via a main hinge. A first drywall flap connected to the first drywall panel via a first hinge, and a second drywall flap connected to the second drywall panel via a second hinge. The first drywall panel, the second drywall panel, the first drywall flap and the second drywall flap can hinge to assume at least one corner configuration in which the first and second flaps lie on a first plane, the first drywall panel lies on a second plane and the second drywall panel lies on a third plane, such that the first plane, the second plane and the third plane are mutually orthogonal. A coating can be provided on an external surface of the framing drywall liner for strengthening the groove which, in embodiments can be polyester strip that extends over portions of the first and second gypsum-containing segments on either side of the of the groove.

Gypsum panels and methods for their manufacture are provided herein. The gypsum panels include a gypsum core having a first surface and a second opposed surface and a first fiberglass mat associated with the first surface of the gypsum core, such that gypsum from the gypsum core penetrates at least a portion of the first fiberglass mat.
