<p>One aspect of the invention is an engineered wood board. The wood board has a major face, and is made up of strips of wood which are oriented with the grain vertical relative to that major face. Additionally, the wood board contains an additive, which is present to improve the exterior durability of the wood. Another aspect of the invention is a method for manufacturing an engineered wood board that has a major face. The method includes the step of obtaining strips of wood that have a flat grain surface and a vertical grain surface. Those strips are assembled side by side, and are oriented with the vertical grain surfaces defining the major face of the board. Once the strips of wood are assembled, they are bonded together. At any stage in the method, a treatment is added to the wood to improve its water repellency and exterior durability.</p> |
