welcome to the future of wood

Accoya® wood 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. Imagine a wood that will act as a better carbon sink during its extended life span. A wood that can be safely recycled at the end. Such a wood exists. It is Accoya® wood: 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. This provides 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 cladding and siding, and even for applications which were once only feasible with non-sustainable materials.

tried and tested

Accoya® wood has been tested over prolonged periods in all types of weathering conditions – above ground, below ground and even in water for 20 years. It has been proven to withstand the toughest of external environments.

The exceptional durability and dimensional stability mean that Accoya® wood requires significantly less maintenance. In fact, test results between Accoya® wood and unmodified wood constantly prove that coatings last up to 3 times as long on Accoya® wood.
