摘要： An insulating radiant barrier sheathing product formed by directly bonding or applying an insulating radiant barrier (IRB) material to the interior surface (i.e., facing the attic or other interior space) of a wood, wood-based, manufactured wood, or cellulosic panel or structural or sheathing panel. The IRB panel product may be used as a roof sheathing panel, with one or more outer protective and finishing layers applied to the outer surface, such as, but not limited to, an underlayment and roofing shingles. The IRB material may comprise a mixture of a radiant barrier (RB) paint and a granulated insulating material. The granulated insulating material may comprise cork, EPS, XPS, poly-iso, other similar insulating material, or combinations thereof.

摘要： An apparatus and method of applying a finish or paint coating in a prefinishing or finishing line to a fencing panel or picket that disguises the screen-back texture of the engineered wood substrate. After paint or similar coating is applied (such as by one or more spray nozzles) to a face to a fence picket or fencing product or component, the fence picket passes under a roller, brush, or roller brush or similar paint applicator while the paint is still wet. The roller/brush removes some of the paint and applies an angled pattern to the face, which disguises the screen-back texture of the substrate.

摘要： A radiant barrier sheathing product formed by directly bonding an unbacked, metallized polyethylene (PET) sheet or film, or similar sheet or film, directly to a wood or cellulosic structural panel. A very thin layer of aluminum (or similar metal) is deposited via vapor deposition manufacturing processes onto one or more sides of a polyethylene sheet to form a metallized PET sheet. The elimination of the backing substrate eliminates the cost and conversion expense of producing a combined overlay product.

摘要： A system for introducing a noise-dampening polymer in-line in the manufacturing process of a manufactured wood product to achieve higher acoustic performance in siding, sheathing, roofing, flooring, and similar applications using the manufactured wood product. Several lines or bands of the noise-dampening polymer are deposited transversely across one side or face of the product. The polymer is deposited where the product is expected to contact joists or studs. The polymer may be a viscoelastic polymer.

摘要： A plurality of ventilation elements, vents, slots, or gap elements or similar features that are applied to, or machined into, one or more sides of exterior siding products, such as lap siding, panel siding, decorative trim, or other cladding materials. When the exterior siding product is installed, the ventilation elements, vents, slots, or gap elements or similar features provide a built-in air and water gap to facilitate and increase water drainage and air circulation behind the siding or panel, thereby minimizing water storage in the space behind the siding and lowering the equilibrium moisture content of the siding itself. The ventilation features are incorporated into the corresponding product in-line or during the manufacturing process, and do not require any further work during assembly or construction on-site (e.g., furring strips or other similar drainage mechanisms are not needed). Some or all of the ventilation features or elements are located to improve the product's ability to equilibrate (moisture-wise) in a product stack before installation as well as after installation.

摘要： An integrated joint sealing system that is incorporated into the edges of a sheathing panel, which also may have a factory bonded weather resistive barrier. The edges of each panel are configured as a shiplap joint, or similarly functioning joint, that is present as either an overlap or underlap on each of the four panel edges. The arrangement of the joints are such that one edge will have an overlap and the opposite edge will have an underlap. A flexible gasket material (or materials) is factory applied to one or both sides (underlap and/or overlap) of the shiplap joint. This flexible gasket material, when overlapped with adjacent shiplap panels, provides a weather resistive seal to limit both water and air penetration.

摘要： A process for producing a smooth-sided strand-based siding or wood structural panel using a secondary pressing process. The secondary pressing process is performed after the primary process completes pressing and consolidation of the substrate/board. The secondary process applies and cures the overlay after applying a water spray on the hot board immediately out of the primary process press, and before overlay application. The application of the water spray causes the surface of the board to swell and cure. A settling period follows to allow the top surface particles and strands to swell along with absorption and evaporation of the moisture. This is followed by surface sanding to remove the telegraphing and produce a smooth surface, which is then followed by lamination of the overlay(s). The process is completed by post-lamination treatment and coating of the board.
摘要翻译：一种使用二次压制工艺生产光滑侧面的基于股线的侧板或木结构板的方法。在主要工艺完成基板/板的压制和固化之后执行第二次压制工艺。二次加工在紧接着一次加工印刷机之外并且在覆盖应用之前对热板施加喷水之后施加和固化覆盖层。水喷雾的施加导致板的表面膨胀并固化。随后的沉降期允许顶部表面颗粒和线股随着水分的吸收和蒸发而膨胀。接着进行表面砂光以除去刻印并产生光滑的表面，然后层压覆盖层。该过程通过后贴合处理和涂覆板完成。

摘要： A method provided for forming a multi-layer lignocellulosic product. The method comprises providing lignocellulosic particles. Then, the particles are initially separated by size into a plurality of fractions of lignocellulosic particles including a fraction of larger lignocellulosic particles and a fraction of smaller lignocellulosic particles. Next, the fraction of larger lignocellulosic particles and the fraction of smaller lignocellulosic particles are treated with an adhesive bonding material and formed into a multi-layer lignocellulosic mat. The mat has at least one core layer comprising said fraction of smaller treated lignocellulosic particles and at least one face layer comprising said fraction of larger treated lignocellulosic particles. The fraction of smaller treated lignocellulosic particles and the fraction of larger treated lignocellulosic particles in said multi-layer lignocellulosic mat are then bonded together to form said multi-layer lignocellulosic product.

摘要： A multi-layer fire-resistance treatment (FRT) panel for use as structural sheathing. The wood structural panel may be OSB or plywood, coated or treated during the manufacturing process with a product that provides fire resistance. The treatment may be integrated with the material forming the wood structural panel, or may be a coating layer applied to the mat or mat layer. A burn-through layer also may be applied. A protective layer comprising a resin-impregnated paper overlay may be applied on one or both sides of the panel.
