Abstract
In one aspect, a method of preparing a composite wood panel is provided herein which includes: providing a flat core formed of cellulosic material having opposing top and bottom faces, wherein a density profile is defined across the core representing density of the core at different locations between the top and bottom faces, the density profile including a first density profile portion extending from the bottom face towards the top face and including a first maximum density, a second density profile portion extending from the top face towards the bottom face and including a second maximum density, and a third density profile portion extending between, and connecting, the first and second density profile portions; removing the top face, and an adjacent layer, of the core to remove the second maximum density and to define an exposed face; and, adhering, using an adhesive, a veneer to the exposed face.
