A corner trim material that is made of a material that will bond with current industry mastics such as all purpose joint compounds, resists impact, resists abrasion, and readily accepts common coatings such as drywall mud, texture and paints. The surface of this material generally does not need to be covered by any secondary fiber based material such as paper to improve bonding or coating on the inside or outside. The material generally consists of a polymer mixed with a fibrous material like pulp or glass fiber. A corner trim piece can be directly extruded from the mix. The corner trim piece can have a center hinge, can be bullnose, and the flanges can optionally have holes or optionally be coated with adhesive.

A vent member includes a first member and a second member. The first member includes a first portion, a second portion offset from the first portion and a first transverse panel extending transversely from the second portion. The second member includes a third portion for being received behind the second portion of the first member, a fourth portion extending below the third portion, a second transverse panel, and a third transverse panel above the second transverse panel. The vent member may be mounted over upper and lower walls.

A wallboard-fastening device for securing first and second wallboards to a framing member in an outside-corner configuration includes: first and second framing panels that connect to each other to form an inner corner seam that fits against the framing member; first and second corner panels that connect to each other to form an outer corner seam; a first bridge panel that connects to (i) the first corner panel to form a first outer seam and (ii) the inner corner seam; a second bridge panel that connects to (i) the second corner panel to form a second outer seam and (ii) the inner corner seam; a first flat-spring flange that connects to the first outer seam to form a first channel sized to accept the first wallboard; and a second flat-spring flange that connects to the second outer seam to form a second channel sized to accept the second wallboard.

Methods, systems, and an apparatus for constructing a termination point in a wall are provided. A rigid, cured cement board is attached to exterior sheathing of the wall. A stop bead apparatus is attached to the rigid, cured cement board at a terminating location of the wall. An edge of a rigid, cured cement board is inserted into a gap formed between a base panel of the stop bead apparatus and the exterior sheathing. A finish layer is applied to an exterior surface of the cement board, whereby the finish layer covers the base panel of the stop bead apparatus.

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.

A casing bead apparatus includes a base panel with at least one opening through the base panel. With the apparatus mounted at a vertical wall, the base panel is disposed along the vertical wall. A stop bead wall extends from the base panel. The stop bead wall includes a first side, a second side opposite the first side, and a flange at a distal end of the stop bead wall distal from the base panel and extending partially over the base panel. A spacing element is disposed at the second side of the stop bead wall. An adhesive element is disposed at the spacing element. With the apparatus mounted at the vertical wall, the adhesive element engages a horizontal surface perpendicular to the vertical wall to adhesively attach the apparatus at the horizontal surface and the spacing element is disposed between the stop bead wall and the horizontal surface.
