A door skin featuring a facing having an exterior surface and an interior surface can be provided. A wood grain pattern portion can be formed in the exterior surface of the facing. The wood grain pattern portion can feature a plurality of grooves formed in the exterior surface of the facing, the grooves are recessed from a first plane of the exterior surface, and tonal portions formed in the exterior surface of the facing. The tonal portions can include at least a first protrusion, a second protrusion, and a third protrusion. Spacing between the first protrusion and the second protrusion can be different from spacing between the second protrusion and the third protrusion.

A method and equipment to form a digital print by applying dry colourants on a surface of a panel, bonding a part of the colourants with a binder and removing the non-bonded colourants from the surface. The method of forming a digital print on a surface of a panel includes displacing the panel under a digital drop application head, applying a liquid binder with the digital drop application head on the surface; applying colourants on the liquid binder and the surface; bonding a part of the colourants to the surface with the liquid binder; removing non-bonded colourants from the surface such that a digital print is formed by the bonded colourants; and applying heat and pressure on the panel, the surface and the bonded colorants such that the colourants are permanently bonded to the surface.

Building panels with a homogenous decorative surface having a wear layer comprising fibres, binders and wear resistant particles. A building panel including a surface layer and a core, the core including wood fibres, and the surface layer including a substantially homogenous mix of wood fibres, a binder and wear resistant particles, the substantially homogenous mix of wood fibres including natural resins.

A system for constructing a deck using laminated veneer wood products, including, but not limited to, laminated veneer decking (LVD). LVD is comprised of multiple layers of wood and other materials, including, but not limited to, non-wood polymer-based materials, thereby providing specific engineered properties to the product. Each veneer layer can be differentially treated with chemicals, biocides, and other additives, depending on the wood species and position of the veneer in the LVD. Similarly, adhesives used in the formation of each veneer may be differentially treated with chemicals, biocides, and other additives. Adhesives used for secondary bonding of veneer layers to form the LVD also may be similarly differentially treated.

A method and equipment to form a digital print by applying dry colorants on a surface of a panel, bonding a part of the colorants with a binder and removing the non-bonded colorants from the surface. The method of forming a digital print on a surface of a panel includes displacing the panel under a digital drop application head, applying a liquid binder with the digital drop application head on the surface; applying colorants on the liquid binder and the surface; bonding a part of the colorants to the surface with the liquid binder; removing non-bonded colorants from the surface such that a digital print is formed by the bonded colorants; and applying heat and pressure on the panel, the surface and the bonded colorants such that the colorants are permanently bonded to the surface.

A method of forming a digital embossing on a surface by bonding hard press particles to a carrier. A liquid binder pattern is applied on the carrier by a digital drop application head. Hard press particles are applied on the carrier and the binder pattern such that some hard press particles are bonded to the carrier by the liquid pattern and non-bonded press particles are removed. The carrier with the bonded hard press particles is pressed to the surface and an embossing is formed when the carrier with the hard press particles is removed.

In one aspect, composite construction materials are described herein. In some embodiments, a composite construction panel comprises a substrate layer, a cover layer separated from the substrate layer by one or more spacers, and at least one mat disposed between the substrate layer and the cover layer, wherein the mat comprises at least one phase change material disposed in at least one phase change region.

A method of forming a digital print on a surface (2) by applying powder of dry ink (15) including colourants (7) on the surface, bonding a part of the dry ink (15) powder to the surface (2) by a digital heating print head (80) such that the digital print is formed by the bonded dry ink colourants (7) and removing non-bonded dry ink (15) from the surface (2).

Various examples are provided for polymer reinforced composite plywood and laminates. In one example, among others, polymer reinforced composite plywood includes a multilayer polymeric film bonded to a first ply of wood veneer and a second ply of wood veneer. A second multilayer polymeric film can be bonded to the second ply of wood veneer and to a third ply of wood veneer. In another example, polymer reinforced composite plywood includes a monolayer polymeric film bonded to a first ply of wood veneer and to a second ply of wood veneer. A second monolayer polymeric film can be bonded to the second ply of wood veneer and to a third ply of wood veneer. In another example, low pressure laminate includes a polymeric film layer bonded to a base layer that forms a protective lamination layer over the base layer.
