Accoya Wood Accsys Group

Durable, stable & sustainable

Accsys is a chemical company focused on the production of Accoya® lumber through the acetylation process. Accoya® wood has been produced by Accsys continuously since 2007. Volume has grown each year it has been sold through a select group of distributors and selected partners in North America, and the world over. The acetylation of lumber was developed by the USDA Forest Products Lab, Madison WI during the 50’s to 90’s. Despite the performance potential, it proved very difficult to scale up; until Accsys developed Accoya®.

Stable wood for exterior applications

Imagine a solid wood that is sourced from fast-growing responsibly managed forests, has zero toxicity and provides dimensional stability and durability that exceeds even the best tropical hardwoods.

Imagine a wood that can replace increasingly scarce tropical hardwoods, treated woods and less sustainable materials in new and existing outdoor applications. Imagine a wood that will act as a better carbon sink during its extended life span and can be safely recycled at the end. Such a wood exists. It is Accoya®: the world’s leading high technology wood.

Natural Science

Spanning eight decades of research, Accoya® wood combines past and present scientific wood acetylation study with a proprietary production process to deliver reliable commercial-scale results.

In producing Accoya® wood, the chemical structure of the wood is modified from the surface to the core, providing a class leading durable and exceptionally stable product. Accoya® wood is fast becoming the material of choice for exterior applications and can be used for virtually anything, from windows to doors, decking to siding and siding, and even for applications which were once only feasible with non-sustainable materials.
