Soli wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material. Engineered wood includes plywood, oriented strand board (OSB) and fiberboard. The fact that a product is made from solid wood is often touted in advertisements. However, using solid wood has advantages and disadvantages.
