Abstract: A multi-layer engineered-wood composite panel or board with a core strand layer, with one or both top and bottom surface layers formed with “fluffy” fiber layers. The fibers may be synthetic or natural. The fibers have anti-settling characteristics. The fibers may be micro-fibrillated cellulose and subsequent cellulose elemental fibrils processed to reduce lignocellulosic recalcitrance and allow the structural integrity of cell walls to be loosened and fibers to be unfolded and exposed. The processed fibers when used as a surface layer provide a denser, smoother and more uniform surface than that obtained with particle-based products.

Abstract: 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 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.

Abstract: Thermally-modified panels, boards, and flooring manufactured from engineered wood, including, but not limited to, oriented-strand board (OSB). These products may be in the form of a sub-floor panel or substrate, a board, a panel, a combined panel, tile, or similar form. Heat treatment or thermal modification of wood or wood-based composites provides wood-based products with improved water resistance, dimensional stability, microbial resistance, and related biological durability with reduced use of harmful chemicals and/or the elimination of hazardous chemical pretreatments.

Abstract: A method to manufacture, on one or more production or manufacturing lines, an integrated roofing product, such as a roofing panel or roofing plank. A blank panel of engineered wood is cut or sawn into a plurality of raw planks or raw panels, each with an outer face, an inner face, a top edge, and a bottom edge. Each raw plank or panel is then processed by cutting or routing a profile into the top edge, the bottom edge, or both; affixing a gasket seal to the profile in the top edge or the bottom edge, or both; coating at least some or all of the outer face with a silicone-based or silicone-containing coating; applying a mix of granules and/or sand to the silicone-based coating while wet; and curing the coated plank or panel. A plurality of panels or planks can then be installed on a roofing structure.

Abstract: An engineered wood product with at least one engineered-wood substrate or core layer (such as, but not limited to, OSB), with a connectivity layer configured to reflect RF signals (e.g., wifi and/or cellular signals), thereby enhancing connectivity in adjacent or proximate spaces or areas. The connectivity layer may be a metallic material, such as, but not limited to, aluminum or copper. The layer may be a sheet or film or foil of the metallic material applied to the surface(s), or integrated into the interior, of the substrate or core layer. The layer also may be a coating or deposited layer. A connectivity layer may be “sandwiched” between two or more engineered-wood substrates, thereby forming a composite panel or product. The surface of the connectivity layer may be embossed or patterned.
