Abstract: An engineered wood based siding, cladding or panel with a fines interface layer between the main strand matrix layers and the fines layer to minimize telegraphing and provide an improved surface appearance. The fines interface layer is applied to the surface of the strand matrix or mat prior to application of the fines layer. The FIL sits between the strand matrix and the fines layer, and prevents the loss of fines into the strand matrix. The FIL thus keeps the fines at the surface so they can effectively and efficiently function to prevent or eliminate strand telegraphing, and provide a smooth finished surface for the product.

Abstract: A plurality of ventilation elements, vents, slots, or gap elements or similar features that are applied to, or machined into, one or more sides or faces of exterior siding products, such as lap siding, panel siding, vertical siding, horizontal siding, flat (or non-overlapping) siding, flap siding, decorative trim, trim system components or other forms of panels or cladding materials. When the exterior siding product is installed, the ventilation elements, vents, slots, or gap elements or similar features provide a built-in air and water gap to facilitate and increase water drainage and air circulation behind the siding or panel, thereby minimizing water storage in the space behind the product and lowering the equilibrium moisture content of the siding itself. The ventilation features are incorporated into the corresponding product in-line or during the manufacturing process, and do not require any further work during assembly or construction on-site (e.g., furring strips or other similar drainage mechanisms are not needed). Some or all of the ventilation features or elements are located to improve the product's ability to equilibrate (moisture-wise) in a product stack before installation as well as after installation.

Abstract: A lap siding product with a unique shiplap joint that spaces abutting pieces of siding correctly from each other without installer measurements. The shiplap joint comprises a bottom element and a top element. A lap siding panel or board has a bottom element shiplap joint at one end, and a top elements shiplap joint at the other end. The corresponding ends of two lap siding panels or boards (i.e., one bottom element and one top element) together form the unique shiplap joint of the present invention. One or more drainage channels or grooves help re-direct water from the joint, and at least one of the channels or grooves also provides a visual element for proper spacing. An engineered “stop” on the underside of the top element also helps space the pieces of siding correctly, without requiring measurement during installation.

IPC: B27D1/00
Abstract: An improved engineered wood product, and related methods, with improved actual and apparent surface quality. The product includes a high basis weight fines layer overlaying a strand matrix base layer, with one or more overlay layers. The fines layer may be placed between the overlay layers, if multiple overlays are present. The configuration of fines layer and overlay layer(s) minimizes the presence of sub-surface imperfections that may result in visible telegraphing on the exposed surface. A light pattern or texture may be embossed on the outermost overlay layer during the pressing process. Additionally, a paint primer layer or coating with added aggregate may be applied to help camouflage inherent sub-surface defects.

Abstract: A manufactured wood panel or board with an integrated conveying laminate that conveys a fire resistant (FR) additive to specific locations within the panel or board during the manufacturing process, and the process and system for producing a panel or board with an FR conveying laminate. The laminate may be a natural or synthetic material with a closed (i.e., solid) or open (i.e., mesh-like) surface. In addition to providing resistance to fire spread and fire combustion, the laminate also may be selected from a group of materials that produce desired structural properties (i.e., minimize cracking, enhance structural integrity) both before and during a particular event, such as a fire event.

Abstract: A lap siding or panel siding product with a unique shiplap joint that spaces abutting pieces of lap siding correctly from each other without measurements taken or needed by the installer. The shiplap joint comprises a bottom element and a top element, each extending from the respective piece of lap or panel siding. A set of “tabs” or “hook-tabs” is engineered on or adjacent to the underside of each joint element to space the pieces of lap or panel siding correctly, without requiring measurement during installation. The locations of the tabs or hook-tabs serve as a stop point for placement of the two pieces of lap or panel siding, allowing self-indexing. Post-installation, as the siding pieces expand or elongate length-wise or laterally, the two tabs or hook-tabs move away from each other, thereby allowing expansion and/or elongation without distortion or warping of the siding pieces.
