摘要： A multi-layered integrated roofing plank or panel with a base layer comprising engineered or manufactured wood, a water resistant barrier layer covering at least the outer face of the base layer, and at least one of the edges of the base layer. A silicone layer may cover at least a portion of the outer face. The silicone layer may be embossed with a pattern. A texturizing material also may be affixed to, or integrated with, the water resistant barrier layer. The edges of the roofing plank or panel may be configured as part of a joint with adjacent planks or panels, including, but not limited to, shiplap joints, tongue -and-groove joints, bead-and-cove joints, butt joints, or combinations or variations thereof.

摘要： An improved engineered wood product, and related methods, with improved actual and apparent surface quality. The product includes a high basis weight fines layer overlaying a strand matrix base layer, with one or more overlay layers. The fines layer may be placed between the overlay layers, if multiple overlays are present. The configuration of fines layer and overlay layer(s) minimizes the presence of sub-surface imperfections that may result in visible telegraphing on the exposed surface. A light pattern or texture may be embossed on the outermost overlay layer during the pressing process. Additionally, a paint primer layer or coating with added aggregate may be applied to help camouflage inherent sub-surface defects.

摘要： An improved blending apparatus for manufactured wood products with a rotating blending drum or cylinder with a pattern of alternating flights of different configurations extending from the interior of the drum. The flights lift the strands as the drum rotates to different heights before the strands free-fall back to the bottom of the drum. One flight is shorter, and may be trapezoidal in cross-section. The second flight is taller, and may have a "bull-nose" configuration with substantially vertical sides. During operation, the alternating pattern causes a more consistent and dispersed fall of strands as the drum rotates, resulting in a significantly larger and more consistent amount of the sprayed adhesives and waxes being applied to the strands, and not passing through gaps to build up on the drum wall.

摘要： A lap siding product with a unique shiplap joint that spaces abutting pieces of siding correctly from each other without installer measurements. The shiplap joint comprises a bottom element and a top element. A lap siding panel or board has a bottom element shiplap joint at one end, and a top elements shiplap joint at the other end. The corresponding ends of two lap siding panels or boards (i.e., one bottom element and one top element) together form the unique shiplap joint of the present invention. An engineered "stop" on the underside of the top element spaces the pieces of siding correctly, without requiring measurement during installation. This also eliminates the need for caulk, pan flashing or joint covers in the joint between the pieces of siding or cladding. The shape of the joint also reduces the intrusion of water, and re-directs water down and out from behind the siding.

摘要： An engineered wood based siding, cladding or panel with a microstrand interface layer (MIL) applied to the top of the main strand matrix layers to minimize telegraphing, add rigidity and strength, and provide an improved surface appearance. The MIL comprises microstrands applied to the surface of the strand matrix or mat during production, prior to deposition of a fines layer. The MIL prevents the loss of fines into the strand matrix, and helps prevent or eliminate strand telegraphing.

摘要： A unique modified shiplap joint with a transverse spline extending into the respective edge of each piece of siding forming the joint. The spline ensures that the two adjacent pieces of siding are properly and adequately connected to each other, and, through the nail in the underlap portion of the joint, to the wall. The spline may be located in four possible positions: (1) attached to the back side of the underlap section of the joint (i.e., closest to the wall); (2) through the center of the underlap section of the joint; (3) directly attached to the front face of the underlap section of the joint; and (4) through the overlap section of the joint (i.e., closest to the outside face). The spline may be installed on one of the pieces of siding during manufacturing or at the factory, or alternatively, at the job site.

摘要： An integrated roofing product comprising a wood or cellulosic structural or roof sheathing base or core panel with a rigid foam insulation sheet or layer laminated or otherwise attached to the panel's inner face. Shingles and/or other protective material may then be attached to the panel's outer face. A plurality of parallel air channels extend vertically in the rigid foam insulation sheet or layer, providing a pathway for air to pass up and out of the cave space. Some or all of the air channels are disposed on the surface of the foam layer that is laminated or attached to the panel's inner face, so that part of the air channel is formed at the interface. A radiant barrier layer may be placed on the inner face of the rigid foam insulation sheet or layer, or between the foam insulation and the inner face of the roof sheathing base or core panel.

摘要： A system and methods for manufacturing and constructing a fence panel or pickets using engineered wood products, including, but not limited to, oriented-strand board, fiber strand, or laminated strand lumber. An entire engineered wood panel is divided into multiple fence blanks of equal size. Each fence blank is then subjected to edge profiling on top and bottom edges, and top feature milling to create fence top features, with finishing, texture, printing, paper overlay, or combinations thereof, added to one or both faces of the blank. Blanks may then have finishing features added to create a finished fence panel. Alternatively, a fence blank can be cut into multiple raw pickets, also with finishing treatments to one or both faces, to create a series of raw pickets. The resulting finished fence panel or pickets provide the authentic look and appeal of real wood, but with the advantages of treated engineered wood.

摘要： A lap siding product with a central face cut, allowing an installer or user to break the lap siding product in half manually, without tools, resulting in two pieces of lap siding. The central face cut extends for the length of the product, and its depth is a substantial portion of the thickness of the lap siding product. A central back cut opposite to the central face cut may be provided, as well as a pair of back spacing cuts along the edges of the back face of the product. A pair of machined nail lines on the face of the product assist in determining locations for nailing the post-break pieces of lap siding during installation.
