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.

Methods of forming a lightweight reinforced thermoplastic core layer and articles including the core layer are described. In some examples, the methods use a combination of thermoplastic material, reinforcing fibers and bicomponent fibers to enhance retention of lofting agents in the core layer. The processes permit the use of less material while still providing sufficient lofting capacity in the final formed core layer.

A flame-retardant, waterproof and formaldehyde-free board is disclosed. The board includes raw material and a coagulant agent. The mass ratio of the raw material to the coagulant agent is 1:1-5. The coagulant includes Agent (A), Agent (B) and magnesium oxide at a mass ratio of 15:2:8-12. In addition, a method of manufacturing the flame-retardant, waterproof and formaldehyde-free board is disclosed.

A wood chip material, especially a fireproof water resistant wood chip material, especially a fireproof water resistant wood chip material to make oriented strand boards which consists of a mixture containing 30 to 43 weight percent of wood chips, 53 to 61.9 weight percent of an aqueous solution of silicate, 2 to 5 weight percent of aluminium hydroxide, 1 to 3 weight percent of water, 0.1 to 1 weight percent of a stabilizer of the aqueous solution of silicate, and a hardener of the aqueous solution of sodium silicate in the concentration of 0.5 to 5 weight percent to the pure aqueous solution of sodium silicate providing always that the density of the aqueous solution of sodium silicate ranges from 1370 to 1400 kg/m.sup.3 and the SiO.sub.2 to NA.sub.2O molar ratio in the aqueous solution of sodium silicate ranges from 3.2 to 3.4. A method of production of a wood chip material, especially method of production of a fireproof water resistant wood chip material, especially method of production of a fireproof water resistant wood chip material to make oriented strand boards according to which, as the first step, the aluminium hydroxide is mixed with water, then wood chips are added into the mixture and everything is stirred thoroughly in such a manner that a wood chip mixture is formed, then the stabilizer of the aqueous solution of sodium silicate is added in the aqueous solution of silicate and after that the hardener of the aqueous solution of sodium silicate is admixed in this solution. Then the solution is stirred for 1 to 10 minutes until a binding solution is formed. Then the wood chip mixture is poured, at continuous stirring, in the binding solution and everything is stirred thoroughly again. Then the resulting mixture is poured in the place of application.

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.

A wood or engineered wood structural panel, such as, but not limited to, OSB (“oriented strand board”) or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

A process for producing a non-woven grass fibre product comprises providing a grass fibre biomass obtained by aerobic fermentation of a meadow grass slurry and removal of digestible elements released during aerobic fermentation, mixing and shaping the grass fibre biomass to form a non-woven grass fibre mat, and binding and drying the mat to form the non-woven grass fibre product.

The present invention relates to furniture panels, and more particularly, to a method for preparing functional engineered wood. It includes the following steps: make veneer blanks by rotary cutting or splicing, and cut the veneer blanks into desired dimensions to obtain veneers A. Soak the veneers A in a ternary mixed solution of a biomass nanocellulose solubilizer, a fire retardant and an acid dye for toughening, fire retardation and dyeing to obtain veneers B. Add a formaldehyde decomposing powder into a modified MUF adhesive, mix them up, coat the veneers B with the mixture to obtain veneers C. Assemble and cold-press the veneers C to obtain flitches D, and saw the flitches D into desired patterns and dimensions to obtain finished products.

System and method for manufacturing bamboo dimensional lumber having cross-hatched fiber layers. The method involves splitting bamboo poles into smaller slats, which are then and crushed into fibers. These fibers are covered with glue, and laid in alternating perpendicular layers. The combined layers are hot pressed to form a rough lumber board composed of cross-hatched bamboo fiber layers. The board is then cut to any desired dimensions for lumber.
