Engineered Wood Products

According to the American Plywood Association (APA), Engineered Wood Products (EWP) are a good choice for the environment. They are manufactured for years of trouble-free, dependable use. They help reduce waste by decreasing disposal costs and product damage. Wood is a renewable resource that is easily manufactured into a variety of viable products.
