Abstract: A method for preparing an overlaid composite product comprises treating a web comprising a functional barrier on one face of the web with a binding agent; placing the treated web directly adjacent an unconsolidated substrate wherein the unconsolidated substrate comprises an uncured first resin; and concurrently consolidating the unconsolidated substrate and curing the binding agent and first resin thereby bonding the web to the substrate without addition of a separate adhesive. An overlaid composite product produced by this method is described. An overlaid composite product can be, e.g., a paper laminated oriented strand board.

Abstract: A load transfer device (LTD) allowing for reliable connection and linkage of composite wood boards is provided. A LTD is configured for containment within openings within peripheral edges of wood boards which are cut into a complementary shape to that of the device. The device, when assembled in panel openings, permits separation of adjacent boards, as well as, sufficient load bearing strength for the overall construction within which such connected wood boards are utilized. The separation of wood boards permits proper sealing therebetween and proper distance for shrinking or swelling during the lifetime of the edifice. The ability to impart increased load bearing strength allows for an increase in construction materials to be carried and kept on such a structure during construction. The method of manufacture of a structure utilizing load transfer devices between boards is also disclosed.

Abstract: A composite wood panel having a first and a second longitudinal edge comprising an essentially parallel first surface and second surface, a core, a spacer integrally formed in or attached in the core on at least the longitudinal edges wherein the spacer extends from an edge a pre-determined distance whereby upon placing one panel adjacent to a second panel a spacer of the first panel will abut a spacer of or an edge of a second panel thereby forming at least a first aperture between the adjacent panels wherein an aperture is located between adjacent edges of the panels. A spacer can push into its panel upon linear expansion of a panel. The spacer can be, e.g., a tongue, edge profile, or separate spacing material. Methods for making and using panels are disclosed.
