Accoya siding is made of FSC-certified wood that has undergone an acetylation process, promising durability, sustainability, and low maintenance. According to the manufacturer, acetylated wood is rot-resistant without containing biocides or harmful chemicals and is likely to stay free of any visible distortion over its lifetime. The siding takes a range of finishes, including Shou Sugi Ban, and comes in custom board sizes and profiles. Left unfinished, the wood will weather naturally. accoya.com
