    摘要： 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.

    摘要： 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.
