Abstract: A panel for a shaftwall system includes a panel body with a core and at least one outer facing layer and an opposite backing surface. A score line is formed in the facing layer, defining two folded panel portions. The panel is folded along the score line to form a folded edge, and the folded panel portions are arranged so that the backing surfaces of the panel portions contact each other. A companion shaftwall building structure system is provided, including a plurality of the panels defining an enclosure, each panel being a ½-inch thick wallboard panel having a “V”-shaped score line defining a pair of panel portions, the score line forms a tapered edge of the folded panel. A plurality of brackets is provided, each bracket defining a panel track dimensioned for slidingly accommodating the folded panel and retaining the panel in place without the use of fasteners.

Abstract: This invention provides low dust low density gypsum wallboard products having high total core void volumes, corresponding to low densities in the range of about 10 to 30 pcf. The wallboards have a set gypsum core formed between two substantially parallel cover sheets, the set gypsum core preferably having a total void volume from about 80% to about 92%, and made from a slurry including stucco, pregelatinized starch, and a naphthalenesulfonate dispersant. The combination of the pregelatinized starch and the naphthalenesulfonate dispersant also provides a glue-like effect in binding the set gypsum crystals together. The wallboard formulation, along with small air bubble voids (and water voids) provides dust control during cutting, sawing, routing, snapping, nailing or screwing down, or drilling of the gypsum-containing products. This invention also provides a method of making the low dust low density gypsum products including the introduction of soap foam in an amount sufficient to form a total void volume, including air voids, preferably from about 80% to about 92% in the set gypsum core, corresponding to a set gypsum core density from about 10 pcf to about 30 pcf. The wallboards produced by the method generate significantly less dust during working.

Abstract: A formable trim strip for use in connection with drywall applications includes two or more layers, including a trim strip body and a backing paper. The trim strip body extends along a body axis and has a top surface and a bottom surface. The trim strip body comprises a polymer material. The backing paper includes a portion secured to the bottom surface of the trim strip body without an intervening layer of adhesive material. The trim strip body is coated onto the portion of the backing paper when a temperature of the trim strip body is within the melting point range such that the bottom surface of the trim strip body contacts the portion of the backing paper. As the trim strip body cools to a temperature below the melting point range, the portion of the backing paper bonds to the bottom surface of the trim strip body.

Abstract: Embodiments of a system and a method for evaluating a joint compound specimen can be used to determine a numerical sandability value for the specimen. A moving assembly is configured to move a sanding member in a sanding direction relative to the joint compound specimen supported in a support fixture. An actuator assembly is configured to drive the sanding member into contacting relationship with the joint compound specimen such that the sanding member exerts a controlled amount of pressure against the joint compound specimen. The force gauge is configured to measure a resistance force against the sanding member in a resistance direction in opposing relationship to the sanding direction. A processor programmed with a joint compound analyzing application is configured to use a force signal from the force gauge that is indicative of the resistance force to determine the sandability value for the joint compound specimen.
