The cove base molding strip includes a body including a planar portion having a front surface and a rear surface and a curved portion having a concave surface continuous with the front surface and a convex surface continuous with the rear surface. The rear surface includes at least a first channel. A cove anchor projects from the convex surface, and the intersection of the front surface and the rear surface define a rounded tip that projects from the planar portion.

A device for laying floor and wall covering for outside corners includes two portions, namely a rigid central first portion that is substantially in the shape of a hollow tetrahedron or of a quarter of a truncated cone, and a flexible peripheral second portion that is substantially triangular in shape and that extends from the periphery of the central portion. The peripheral portion comes to bear against the floor portion and against the wall portions that are disposed facing the device.

The present invention relates to a polymeric cove base support for installation where flooring meets a wall, comprising extruded straight portions and molded exterior corner and end portions. The cove base support comprises an upper wall portion, a lower toe portion and an intermediate curved or concave cove. The wall portion is substantially perpendicular to the toe portion. The curved cove comprises an outer cove surface for facing the wall-floor interface and a spaced apart inner curved cove surface facing the room when installed. The spacing between the two curved coves for the straight portion creates an open area, where the open area includes a supporting or reinforcing bar juxtaposed between the curves, preferably positioned perpendicular between the two curve coves in the center region of the open area, and extending the length of the cove base. The corner and end portions have outside surfaces facing the wall and a floor, the outside surfaces defined in part by spaced ribs extending perpendicular to each of the toe and wall portions.

A system for crown molding that enables safely incorporating electrical and communications cabling within crown molding by creating one or more protected paths which inherently prevent overly sharp bends in crown molding corners and by mitigating damage from penetrating punctures through a decorated face designed to fracture when improperly penetrated by a screw or nail, and enables the secure installation of hardware either concealed within the molding or securely and favorably positioned through the decorative face to view or sense a room, and enables additional cable capacity that is concealed within a light reflector to increase lighting efficacy as well as power and data delivery capacity.

A crown molding assembly that enables safely incorporating electrical and communications cabling within the crown molding by providing segregated compartments for electrical and copper communications cabling, wherein the decorative face is formed of a composite of fiber reinforcing polymer (FRP) including a fiber-reinforced structure having an increased directionality of said reinforcing fibers causing the decorative face to fracture upon being pierced by a fastener in a manner that renders the damaged section of the decorative face unable to hold the fastener, protecting the electrical cables and any other equipment located behind the decorative face from damage, and enables the secure installation of hardware either concealed within the molding or securely and favorably positioned through the decorative face to view or sense a room, and enables additional cable capacity that is concealed within a light reflector to increase lighting efficacy and power and data delivery capacity.

A method for determining an edge profile of a custom decorative article to be installed in an installation area is disclosed, the installation area having a perimeter having a plurality of corners. A computing device receives data indicative of a plurality of coordinates corresponding to the plurality of corners of the perimeter of the installation area. Based on at least first, second, and third coordinates respectively corresponding to first, second, and third corners of the plurality of corners of the perimeter of the installation area, the computing device determines dimensional and/or geometric characteristics of a pair of opposed portions of the edge profile that, in an installed position, are configured to meet to form a corner of the custom decorative article when installed at the second corner of the perimeter of the installation area.

A construction component comprising a foamed cellular board comprising smooth exterior surfaces separated by a cellular network and cut edges, and sealed caps adhered to the cut edges on the foamed cellular boar. The board has a density of less than 0.55 g/cm.sup.3, and the cut edges on which the sealed caps are adhered are unmelted edges.

A molding system installed at or near the top of a vertical wall having a molding portion and an attachment portion, where the attachment portion is attached securely to the wall above at least the center of mass of the molding portion, and the molding portion has an outwardly visible decorative face which extends down to where the lower edge of the molding portion meets the wall. The attachment portion is enabled to flex as it is firmly attached to an imperfect wall, and the structure of the molding portion is such that the decorative face of the molding system remains preferentially straight and preferentially positioned as the molding system is installed on an irregular wall. A hinge-like flex is enabled along the length of the molding above the center of mass of the molding portion such that the decorative face of the molding can pivot like a pendulum ensuring the lower edge of the molding is placed against the wall. None of the methods of installation of this system violate the decorative face of the molding and a consistent decorative face profile extends around the entire installation.

A trim piece for sealing a work surface including a body having a first side, a second side, and a span disposed between the first side and the second side, wherein the first side and the second side are joined at a junction defining an angle between the first side and the second side of between 80 degrees and 100 degrees, a topcap is affixed to the span of the body, wherein the topcap includes a left side having a first wing and a right side having a second wing, an adhesive is bonded to the first side of the body and an aperture is disposed within the body.
