Our Accoya®-based products represent the cutting edge in wood treatment and finishing. All Accoya® wood is sustainably-sourced, and processed through acetylation to create a durable and stable product throughout the core of the entire wood board.We use Accoya® in our Shou Sugi Ban products to create a strong charred face that won’t easily damage through normal handling. We also utilize and recommend Accoya® for exterior installations, due to its ability to withstand exposure to the elements.
