Sustainable Lumber Co.’s Prefabricated Architectural Wall Panels are made from reclaimed pallet boards, barn wood and recycled flooring. The indoor-only panels are designed for clean, quick and easy installation. Prefabricated Architectural Wall Panels are available in two colors: Barnwood Grey and All Natural Pallet Wood. Barnwood Grey panels are stained and sealed; the All Natural Pallet Wood contains no stain or sealer. Each panel is 1-inch thick and measures 12-inches tall by 48-inches wide. The company’s patent-pending interlocking and ship-lap panel design reduces labor costs and installation time by as much as 90 percent.
