Abstract: A system, flashing apparatus, and associated methods for protecting vertical butt joints in installed siding having locking profiles. The lower profiled edge of the siding is modified proximate the ends during manufacture or in a factory setting to create a modified section configured to mate with a unique piece of factory-produced or pre-made flashing of similar or matching profile. The flashing piece fits with the ends of the adjacent siding boards in a horizontal row and aligns with the profile of the locking edges of vertically adjacent siding boards so the system sheds water effectively and prevents water from penetrating behind the siding. In addition, the factory-modified siding and the pre-manufactured flashing pieces may be supplied as a ready-to-install system that simplifies the siding installation process and shortens the time and cost of installation.

Abstract: A unique modified shiplap joint with matching or corresponding reverse curves on opposing edges or ends of a piece of siding, each forming one-half of the joint: an underlap edge, and an overlap edge. The respective curves engage and resist or prevent separation of the edges, particularly under a pre-determined wind load. A fastener channel in the underlap section allows for a nail or fastener to be used, while the nail head is then covered by the adjacent overlap section. The respective edges form an angled gap, which is configured to prevent water or rain from entering.

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.
