Accoya

ITI NZ

Accoya® is the world leading high-technology wood. It is produced from a non-toxic cellular modification process known as acetylation. The softwood used in this process is Radiata Pine sourced from sustainably managed forests in New Zealand. The result is a durable, stable and non-toxic material with performance characteristics better than any hardwood. Accoya holds industry-leading environmental credentials. The exceptional durability of Accoya is warranted for a minimum life of 50 years above ground and 25 years in the ground. 

Accoya wood is perfect for many outdoor and indoor applications such as cladding, decking, panelling, timber fins, fences and joinery. 

Board lengths range from 1.8m to 4.8m
