Abstract: A system for constructing a deck using engineered wood products, including, but not limited to, structural composite lumber (SCL). Deck boards may be formed from a plurality of veneer layers treated with fire protection treatments, preservatives and/or other chemical treatments, which may be specific to a particular veneer layer, and assembled with adhesives binding the layers together in a stack, resulting in a deck board with unique properties in aggregate. The veneer layers directly adjacent to the two outer face layers may be positioned so that the direction of the wood grain is cross-directional to the direction of the wood grain in the surface layers. The boards are also subject to a multi-layer surface finishing treatment with aesthetic components and a protective component.

Abstract: An assembly with acoustic dampening properties for use in building or structure construction, a first panel, a second panel, and one or more connection elements therebetween. The first panel is a manufactured-wood acoustic panel with multiple lignocellulosic material-based layers, wherein one or more of the layers having a noise-reducing polymer integrally coating or permeating the lignocellulosic material. The noise-reducing polymer does not form a homogenous layer. The assembly can include insulation, gypsum board, or similar materials to form wall assemblies, roof assemblies, floor assemblies, and ceiling assemblies.

Abstract: A manufacturing process for manufacturing wood products with acoustic dampening properties. A noise-dampening polymer is introduced in-line in the manufacturing process to achieve higher acoustic performance. The polymer can be a viscoelastic polymer which is added during blending of the lignocellulosic strands prior to mat formation, or sprayed or otherwise coated on the lignocellulosic strands during mat formation, prior to formation of any boards or panels.
