Abstract: An example plasterboard includes a layer of hardened plaster having a first surface and an opposed second surface, a layer of polymer material having particles of one or more cementitiously-active substances mixed therein, and a liner between the first surface of the layer of hardened plaster and the layer of polymer material. Another example is a method of forming such a plasterboard. The method includes loading an extruder with the polymer material having the particles of one or more cementitiously active substances mixed therein, extruding the polymer material through a die to form the layer of polymer material on a surface of the liner, contacting with a layer of wet plaster material, the liner having the polymer material applied thereon such that the surface of the liner faces away from the wet plaster material, and drying the layer of wet plaster material to form the layer of hardened plaster.

Abstract: An example plasterboard includes a layer of hardened plaster material having a first surface and an opposed second surface and a layer of molded material having a surface that faces away from the layer of hardened plaster material. The surface of the layer of molded material has one or more raised features. The plasterboard also includes a liner between the first surface of the layer of hardened plaster material and the layer of molded material. Other examples include a method of forming such plasterboards and a method for installing such plasterboards.

Abstract: The present disclosure relates generally to building surface joint supports, for example, suitable for covering a seam between two building surface panels. In certain aspects, the disclosure provides joint supports that include an elongate layered structure having inside and outside surfaces, the elongate layered structure including a support strip that includes first and second elongate flanges. In certain embodiments, the elongate layered structure also includes an inner facing sheet disposed on the inside surface of the support strip; and an outer facing sheet disposed on the outside surface of the support strip, wherein the each of the inner facing sheet and the outer facing sheet is formed from a fibrous polymer material. In other embodiments, each flange of the first and second elongate flanges includes apertures therethrough, each aperture having a width that extends laterally across at least 50% of the width of the respective flange; and the elongate layer structure also includes an outer facing sheet disposed on the outside surface of the support strip.

Abstract: The present disclosure relates generally to building surface joint supports, for example, suitable for covering a seam between two building surface panels, such as drywall. The present disclosure relates more particularly to a joint support including an encapsulated adhesive for securing the joint support to the building surface panels. The joint support includes a support strip having a width, a length, a first end, a second end, a contact surface, and an outer surface. An adhesive is disposed on the contact surface of the support strip. The adhesive includes a first set of capsules and each capsule of the first set of capsules includes a membrane enclosing a first component of an adhesive composition.
