  • Patent number: 8065851
    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.

  • Publication number: 20070157994
    Abstract: An overall method of making engineered strand wood products in relation to a number of different possible criteria is provided. Such a method may involve any combination of different screening procedures to determine the best wood sources from which individual strands may be prepared. Such screening procedures may include initial determinations of certain physical characteristics of individual logs, further or initial determinations of certain physical characteristics of portions of sawn logs, further or initial determinations of certain physical characteristics of individual strands, and any combinations thereof. Additionally, after the initial physical characteristic sorting is completed, optionally the wood may be cut into uniformly sized and shaped strands for incorporation within a target strand product.
