A drywall board system for use in conjunction with a baseboard is described. The drywall board system includes a drywall board for securing to framing members and a baseboard backing that receives a baseboard to form a reveal.

A mobile home skirting base comprising: a horizontal surface; and two substantially equal, substantially symmetrical vertical surfaces co-extruded with the horizontal surface forming a channel to insert a mobile home skirting panel wherein the vertical surfaces each having an inwardly oriented retention edge that secure the mobile home skirting panel. The height of the vertical surfaces and the inward orientation of the vertical surfaces' retention edges, along with the other aspects of the invention, allows the mobile home skirting base to provide strong support, stabilization, and protection of the skirting panels.

An apparatus includes a body assembly configured for installation relative to a wall assembly that extends vertically. The wall assembly is supported by a wall-support structure that extends vertically. The wall assembly has a wall edge. The wall-support structure is positioned proximate to any one of a sub-floor and a finish floor that extends horizontally. The body assembly includes a wall-support contact portion configured to be coupled to the wall-support structure. The wall-support contact portion extends vertically. A finished-edge portion extends horizontally from the wall-support contact portion in such a way that the finished-edge portion is spaced apart from any one of the sub-floor and the finish floor. A horizontal portion extends vertically from the finished-edge portion. A wall-contact portion extends upwardly from the horizontal portion. A visual-reveal feature is formed between the finished-edge portion and the top of any one of the sub-floor and the finish floor.

A reglet may include a first base extending in a first plane. A reglet may include a first backbone integrally formed with and extending from the first base in a second plane that is substantially perpendicular to the first plane. A reglet may include a first mud flange integrally formed with and extending from the first backbone in a third plane that is substantially perpendicular to the second plane and substantially parallel to and spaced apart from the first plane. A reglet may include a second side forming an angle of between 0 and 180 degrees with the first side of the reglet, wherein the first side and the second side of the reglet are integrally formed to meet at a corner.

A system of a skirting board (1) and at least one fixing element (2) for connecting the skirting board (1) with a floor (P) and an adjacent wall (S). the fixing element (2) comprising a rigid part (3) to be fixed immovably to the wall (S) and a resilient assembly (4) engaging the skirting board (1), the skirting board (1) comprising an internal shelf (7) extending towards the fixing element (2). wherein the resilient assembly (4) comprises at least one resilient arm (6) extending parallel to the wall (S) and being adapted to resiliently deflect parallel to the wall (S), said at least one resilient arm (6) projects obliquely from the rigid part (3) towards the floor (P) and has a free ending (6), said shelf (7) comprising a coupling protrusion (8) adapted to be snapped with said fee ending (6) so that said coupling protrusion (8) is pressed by the at least one resilient arm (6) in a direction different from horizontal. in particular in a direction selected from a group comprising the vertical direction and a direction slanting both to the wall (S) and the floor (P).

A system comprises a first baseboard element, a second baseboard element, and a spline configured to couple with the first baseboard element and the second baseboard element. Another system comprises a first crown element, a second crown element, and a spline configured to couple with the first crown element and the second crown element. Other embodiments are disclosed herein.
