An engineered wood based siding, cladding or panel with a microstrand interface layer (MIL) applied to the top of the main strand matrix layers to minimize telegraphing, add rigidity and strength, and provide an improved surface appearance. The MIL comprises microstrands applied to the surface of the strand matrix or mat during production, prior to deposition of a fines layer. The MIL prevents the loss of fines into the strand matrix, and helps prevent or eliminate strand telegraphing.

Microstrand interface layer for improved engineered wood products

An integrated joint sealing system that is incorporated into the edges of a sheathing panel, which also may have a factory bonded weather resistive barrier. The edges of each panel are configured as a shiplap joint, or similarly functioning joint, that is present as either an overlap or underlap on each of the four panel edges. The arrangement of the joints are such that one edge will have an overlap and the opposite edge will have an underlap. A flexible gasket material (or materials) is factory applied to one or both sides (underlap and/or overlap) of the shiplap joint. This flexible gasket material, when overlapped with adjacent shiplap panels, provides a weather resistive seal to limit both water and air penetration.

Integrated joint sealing system

An engineered wood based siding, cladding or panel with a pre-consolidated fines layer (PCF) applied to the top of the main strand matrix layers to minimize telegraphing and provide an improved surface appearance. The PCF is consolidated prior to application to the surface of the strand matrix or mat, and takes the place of a loose fines layer. The PCF prevents the loss of fines into the strand matrix, effectively keeping 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.

A wood or engineered wood structural panel, such as, but not limited to, OSB ('oriented strand board') or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

Fire-rated structural OSB panels with overlaid water-resistant barrier

A mesh tape bonded to the outer edge or outward side of sheet panel products. The mesh tape is applied so that the tape overhangs the edge of the panel for the purpose of adjoining to the adjacent panel following installation of the panels at a job site. The mesh may be applied to two edges of the sheet panel, one along the panel width and another along the panel length. When installed, the panel edge with the mesh tape applied is overlapped with the edge of an adjacent panel that does not have tape applied, both along the length and width, thus allowing for a faster, more robust and reliable installation of panel sheathing.
