Embodiment Construction

[0018] now refer to figure 1 , the present corner bead, generally indicated at 10 , is shown mounted over a siding corner 12 formed by the approximately 90° intersection of adjacent edges of two siding panels 14 and 16 . The panels 14, 16 are secured by fasteners to a frame member 18, typically made of wood or metal, as is known in the art. The procedures for attaching the siding panels 14, 16 are well known to those skilled in the art. It is desirable to apply the present corner bead 10 to produce a finished wall that can be easily painted. The corner bead 10 is secured to the corner 12 using siding joint compound and fasteners such as screws or nails, as is known in the art.

[0019] now refer to Figure 1 to Figure 4 , in general, the present corner bead 10 is formed as an elongated strip 20 formed from a web of at least one nonwoven fabric layer, which is subsequently impregnated with resin and shaped to form a shape typically at about 80-90° or Corners at other desire...

Abstract

A preformed corner bead (10) for use in wallboard construction is provided and includes an elongate strip (20) formed of a web of at least one layer of non-woven fabric, a resin impregnating the strip.

Description

technical field [0001] The present application relates generally to siding construction techniques and materials, and more particularly to corner beading used to form durable, aesthetically pleasing corners at the junction of adjacent siding panels during interior construction. Background technique [0002] During siding construction, the joints or seams formed by adjacent siding panels are typically completed using paper or fiber tape extending the length of the joint. Siding joint compound is then applied to the strip and feathered or troweled. When dry, the joint compound is sanded and reapplied as needed to create a smooth, seamless joint. To complete the exterior corners, metal or plastic corner beading is typically installed. In many applications, the metal bead is fastened to the corner in some way with fasteners or chemical adhesives. Corner beading is also used in some applications to protect inside (concave) corners. [0003] Corner beading is traditionally man...
