Abstract: A cornerbead for installation at a drywall outside corner includes a substrate forming a nose and first and second elongated flanges. Each flange has an inner edge and an opposing outer edge and joins an opposing side of the nose at the flange's respective inner edge. Each flange is formed with discrete holes. There is pressure sensitive adhesive on the interior surface of at least the first flange.

Abstract: A trim piece for installing at a drywall external right angle corner which is provided with a bullnose corner bead includes an intermediate portion which wraps over the convexly curved portion of the bullnose corner bead and has two edges extending parallel to the edges of the flanges of the corner bead. Two leaves are attached to the intermediate portion of the trim piece at the two edges respectively. The intermediate portion of the trim piece has an interior surface at a first end matching closely the exterior surface of the corner bead and an exterior surface which is convexly curved at the first end and is right-angled at the opposite second end and provides a transition from the convex curve to the right angle between the first and second ends.

Abstract: A bottom sill finish material for a window opening is made of synthetic polymer material and has a return portion which extends into the window opening, a sill projection which extends from the return portion beyond vertical wall in which the window opening is formed, and a molding profile portion which extends downward from the sill projection, substantially perpendicular to the return portion.
