Accoya is the benchmark in high-performance modified timber. Through a proprietary wood-acetylation process developed by Accsys Technologies, fast-growing, sustainably sourced softwood is transformed into a remarkably durable, dimensionally stable and versatile material. The result: a wood product that out-performs traditional hardwoods and many man-made alternatives, while offering outstanding environmental credentials.
Superior durability & long life
Accoya is classified in the highest durability class (Class 1) and carries warranties such as 50 years above ground and 25 years when in-ground or freshwater exposure.
Exceptional dimensional stability
Thanks to the acetylation process, Accoya resists swelling, shrinking, twisting and warping much more than standard timbers, making it reliable in variable climates.
Strong sustainability & environmental credentials
Accoya is made from fast-growing, sustainably managed forests (FSC or PEFC certified), is non-toxic, 100% recyclable and holds certifications including Cradle to Cradle Gold.
