Extrusion devices for mounting wall panels

An extrusion device for mounting a wall panel has an outer cap extending to an edge on at least one side which is positioned against an outer surface of a wall panel, having a pair of spaced-apart insertion fingers, and a receiver base having a planar mounting portion and a pair of angled receiver flanges projecting upwardly to receive the insertion fingers therein. The two-piece extrusion permits wall panels to be mounted or removed from the underlying wall structure in on-sequential order. The receiver base and cap can be provided on both sides to form an "H" type extrusion, or on only one side in a "J" type extrusion. Preferably, the outer cap is made of metal, and the tips of the insertion fingers are beveled at a slight angle of about 7° to 14° to allow easy insertion into the receiver flanges. The cap has compound water-shedding edges formed with a rounded rain-drip edge spaced in close proximity to a sharply inclined knife edge. In another variation, a one-piece extrusion device has a rear base portion and a front cover portion forming a pocket therewith, and a ramp formed on the base portion within the width of the front cover portion for gradually forcing the edge of a wall panel inserted in the pocket toward the front cover portion clear of the heads of screws used to mount the base portion to the underlying wall structure. The base portion is formed with a hook indentation on a back side of the ramp on a rear surface of the base portion, and interconnects with a "Z" type extrusion having a hook end to form a right angle connection. The one-piece extrusion may be formed as a "J" (one-sided), "H" (two sided), "C" (corner), or other suitable types.

Composite light weight gypsum wallboard

The invention generally provides a light weight composite gypsum board including a foamed low density set gypsum core, a top non-foamed (or reduced-foamed) bonding high density layer and a bottom non-foamed (or reduced-foamed) bonding high density layer, a top cover sheet bonded to the foamed low density set gypsum core by the top non-foamed (or reduced-foamed) bonding high density layer, and a bottom cover sheet bonded to the foamed low density set gypsum core by the bottom non-foamed (or reduced-foamed) bonding high density layer. The foamed low density set gypsum core and the non-foamed (or reduced-foamed) bonding high density layers are made from a gypsum slurry including stucco, pregelatinized starch present in an amount of about 0.5-10% by weight based on the weight of stucco, preferably a naphthalenesulfonate disperant present in an amount of about 0.1-3.0% by weight based on the weight of stucco, and preferably sodium trimetaphosphate present in an amount of about 0.12-0.4% by weight based on the weight of stucco. Other slurry additives can include accelerators, binders, paper fiber, glass fiber, and other known ingredients. The foamed low density set gypsum core is prepared having a density of less than about 30 pcf using soap foam in the gypsum-containing slurry. The combination of components provide a composite gypsum board having light weight and high strength. A method of making the composite gypsum board is also provided.

Strengthened, light weight wallboard and method and apparatus for making the same

A novel wallboard composition is disclosed comprising a unique combination of synthetic binders selected for their ability to establish a strengthened permanent bond in the final dry state for use in a wallboard composition comprising primarily gypsum, and in a wallboard composition comprising an expanded mineral such as Perlite which largely reduces the amount of gypsum over current gypsum wallboard formulations, thus reducing the weight while maintaining the strength of the wallboard structure. In a preferred embodiment, the lightweight, strengthened wallboard of the present invention also comprises an optional covering veneer that is applied to the top ply of the face paper to provide increased strength, moisture resistance, and fire retardency, and the back paper top ply is treated to provide increased flexural strength. Additionally, this invention relates to the unique manufacturing process to produce the wallboard composition of the present invention in order to create a lightweight, strengthened, moisture resistant, and fire retardant wallboard used to cover walls and ceilings in construction applications. Still further, this invention relates to the apparatus for manufacturing the wallboard composition of the present invention, including a method and apparatus for economically converting a standard gypsum wallboard manufacturing facility into a facility for manufacturing wallboard of the present invention.

Fire-rated joint system

A fire-rated angle piece and wall assemblies or other assemblies that incorporate the fire-rated angle piece, in which the angle piece can include an intumescent or other fire-resistant material strip. The angle can be attached adjacent to a corner of a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed between the framing member and a wall board member at a perimeter of a wall assembly to create a fire block arrangement. A fire spray material can be applied over a portion of the angle piece.

Composite facer for wallboards

A composite facer material for use with cementitious wallboards, where the composite facer is embedded in a top and bottom face thereof. The composite facer material, in a most preferred embodiment, comprises two layers. The first layer is preferably a carded polyester nonwoven mat, which is bonded to a second layer comprising preferably a tri-directional laid scrim fabric reinforcement layer made of continuous glass fibers. The two layers are preferably bonded together using an acrylic adhesive, which offers superior adhesion between the layers as well as superior adhesion between the composite facing material and the cementitious core.

Wall panel system with insert

A wall panel system including a mounting bracket, a wall panel, and a clip attached to the wall panel, the clip having an engaging element that secures it to the mounting bracket. The wall panel system also includes a slot in the clip facing outwardly from the wall panel, a spline slidably positioned in the slot of the clip, and a sealing insert positioned between the mounting bracket and the spline. The sealing insert may be in the shape of an X, and may be made from polypropylene foam. The sealing insert may also have a gasket tape on one side to provide an improved seal.
