In one aspect, the present disclosure relates generally to a set acoustic adhesive composition having a storage modulus at 20° C. of at least 2.0 MPa over a frequency of 1-10 kHz, the set acoustic adhesive composition comprising: a continuous phase of a viscoelastic material present in an amount in the range of 60-95 wt % of the set adhesive composition; and dispersed in the continuous phase, a particulate polymer filler present in an amount in the range of 5-40 wt % of the set adhesive composition, wherein the particulate polymer filler has a storage modulus at 20° C. of at least 50 times a storage modulus at 20° C. of the continuous phase at 20° C., over a frequency of 1-10 kHz; and/or the viscoelastic material of the continuous phase has a glass transition temperature (T g ) no greater than 0° C., and the particulate polymer filler has a glass transition temperature (T g ) of at least 60° C.

The present disclosure relates generally to plaster wall panels, for example, suitable for covering interior wall frames. The present disclosure relates more particularly to a plaster wall panel including a first plaster layer, a second plaster layer, and a damping layer disposed between the first and second plaster layers. The first plaster layer has a first thickness and is composed of a first plaster material that has a first material property. The second plaster layer has a second thickness and is composed of a second plaster material that has a second material property. The first thickness is smaller than the second thickness, and the first and second material properties are different.

A gypsum-based construction material may include a gypsum core. The gypsum core may have a core bubble median size (D50) of at least about 150 microns and not greater than about 600 microns, and a contacting bubble surface percentage of not greater than about 50%. The gypsum core may further have a water absorption of not greater than about 5.0%.

A system and method for indicating a force applied to a tool is disclosed. The system can include a tool configured to engage a surface of a building; a handle configured to apply a first force to the tool, and a force indicator configured to indicate a representation of the first force to an operator. The method can include receiving a first force at a first tool, where a handle is configured to apply the first force to the first tool and cause the first tool to engage a surface of a building; and indicating, via a force indicator, a first indication to an operator when the first force is within a first predetermined range.

The present disclosure relates to a plaster board comprising a first panel having an outer surface, an inner surface, a first edge, a second edge, and a center between the first edge and the second edge, a layer of hardened plaster material coupled to the inner surface of the first panel, wherein the hardened plaster material has a first density proximate the first edge of the first panel and a second density proximate the center of the first panel, the first density being greater than the second density, and a second panel having an outer surface, an inner surface, a first edge, a second edge, and a center between the first edge and the second edge, wherein the second panel is coupled to the hardened plaster material opposite the first panel.

An elongated element can include a first flange and a second flange, where the first flange is joined to the second flange at an apex, and a reinforcement element can be embedded within the elongated element, where the reinforcement element is made from a first material and the elongated element is made from a second material, wherein the first material is different than the second material. A method can include extruding a reinforcement element from a first material, feeding the reinforcement element to an extruder, extruding a body of an elongated element from a second material, where the body comprises a first flange, a second flange, and a first apex, where the first flange is joined to the second flange at the first apex, and where the first material is different than the second material, and embedding the reinforcement element into the body.

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.

The present disclosure relates generally to building surface systems, for example, suitable for forming an internal or external surface of a building. The present disclosure relates more particularly to a building surface system including a support structure and a plurality of building surface products attached to the support structure. The support structure includes a first vertical rail that has a longitudinal section and a vertical receiving slot in the longitudinal section. A first building surface product includes a panel and a first attachment post extending outward from a rear surface of the panel. The first attachment post includes a shaft that extends through the vertical receiving slot of the first vertical rail such that the longitudinal section of the first vertical rail is clamped between a head of the first attachment post and the rear surface of the panel so as to secure the first building surface product against the support structure.
