The present disclosure relates generally to building surface products, for example, suitable for forming a building surface. The present disclosure relates more particularly to a building surface product including a panel having a front surface, a rear surface, and a gypsum body between the front surface and rear surface. A first attachment clip is secured to the rear surface of the panel and includes a first leg extending outward from the rear surface of the panel. A retaining flange is coupled to the first leg and extends over the rear surface in a first direction. The retaining flange includes a slot that is configured to receive a post so as to secure the building surface product to a support structure. A first fastener that penetrates the rear surface of the panel is attached to the first leg so as to secure the attachment clip to the panel.

Building surface product including attachment clip, building surface system, and method of manufacture

The present disclosure relates generally to wallboards, for example, suitable for use in constructing internal walls. The present disclosure relates more particularly to a wallboard and a method that provides simplified high-quality surface finishing. The wallboard includes a wall panel having a front surface and a rear surface. A sandable coating is disposed on the front surface of the wall panel. The method includes positioning wallboards adjacent to one another, applying sandable joint compound over joint formed between the wallboards, and sanding the joint compound and the sandable coating of the wallboards.

Wallboards, wallboard systems and methods for installing them

The present disclosure relates generally to building surface products, for example, panels suitable for forming a building surface. The present disclosure relates more particularly to a building surface product including a gypsum panel with an upper edge that overlaps a lower edge of a neighboring gypsum panel.

Interlocking gypsum building surface products, methods of manufacture, and interlocking gypsum building surface systems

The present disclosure relates to devices and methods for determining the density of insulation. For example, one aspect of the disclosure is a device that includes a sound generator and one or more sound sensors configured to detect sound that is generated by the sound generator and transmitted through the insulation to the one or more sound sensors. The device also includes a control system configured to cause the sound generator to generate the sound and use the sound detected by the one or more sound sensors to generate output that represents the density of the insulation. Another aspect of the disclosure is a method for using the device to determine the density of insulation.
