A third-party environmental study commissioned by the Western Red Cedar Lumber Association revealed that Western Red Cedar siding and decking, such as Knotty Beveled Siding (shown), outperforms its vinyl, fiber cement, brick, and composite counterparts in all seven criteria for decking and five of the seven criteria for siding. The siding is available in Select Knotty, Architect Knotty, Quality Knotty, and Proprietary knotty grades. Beveled options include Plain Bevel, Rabbetted Bevel, and Wavy Edge Bevel. Boards range from 5/8" by 6" to 7/8" by 12", depending on the style selected. wrcla.org
