EXTERIOR ENGINEERED WOOD DECK SYSTEM
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.
1 . A deck board for an exterior deck, comprising:
a substrate with a top, bottom, front edge, back edge, first end, and second end, said substrate comprising a plurality of layers adhered to one another;
further wherein one or more of the plurality of layers is treated individually and independently of at least one of the remaining substrate layers prior to formation of the substrate;
further wherein said individual treatment constitutes application of one or more of a preservative, a fire retardant, and a fire protection or resistance treatment.
2 . The deck board of claim 1 , wherein said fire protection or resistance treatment constitutes one or more of a combustion resistant, flame spread resistant, and ignition resistant treatment.
3 . The deck board of claim 1 , wherein said individual treatment comprises application of an adhesive.
4 . The deck board of claim 1 , wherein said plurality of layers comprises a top surface layer, a bottom surface layer, a first subsurface layer immediately adjacent to the top surface layer, a second subsurface layer immediately adjacent to the bottom surface layer, and a plurality of interior layers therebetween.
5 . The deck board of claim 4 , wherein the first subsurface layer is positioned cross-directionally with respect to the top surface layer.
6 . The deck board of claim 4 , wherein the first second subsurface layer is positioned cross-directionally with respect to the top surface layer.
7 . The deck board of claim 5 , wherein each layer has a wood grain orientation, and the wood grain orientation of the first and second surface layers is cross-directionally oriented with the respect to the wood grain orientation of the top surface layer and bottom surface layer.
8 . The deck board of claim 1 , further comprising one or more aesthetic layers and/or one or more protective layers on the top of the substrate.
9 . The deck board of claim 1 , further comprising a base layer and a visual aesthetic layer on the top of the substrate, and a protective layer overlaying the base layer and visual aesthetic layer.
10 . The deck board of claim 8 , further comprising one or more aesthetic layers and/or one or more protective layers on the top of the substrate.
11 . The deck board of claim 1 , wherein the visual aesthetic layer comprises a digitally printed image or images.
