Accoya® is wood, but not as you know it. It is modified timber in which a process called acetylation, a cutting-edge patented technology, enables it to resist rot, defy the elements and stay strong for decades. Guaranteed for 50 years above ground and 25 years in ground or freshwater, its performance and properties are remarkable. From joinery for the home to bridges submerged in water, Accoya® long life wood is a leading material that stands up to every application challenge – wood decking, wood cladding, landscape timbers, sidings, wood windows and more. TimberTown offers Exterior Accoya® Wood Cladding as well as Accoya® Wood Decking at both our Austin and Atlanta Locations.
