By the time Snavely acquired the remaining stock of Perennial Wood, Weinstein was fully on board with acetylated lumber. He’d bounced around the wood industry, getting interested first in thermally modified lumber and working on a manufacturing venture that ultimately failed.
Typical attack of the late wood in the acetylated SYP (non-Accoya) after exposure to M. darwiniensis in a Hazard Class H3 field trial.
Acetylated wood has been studied for many decades. It has been under commercialization for over 25 years, but cost limited its adoption. Basically, a chemical is added (acetic acid) to the wood and a chemical reaction takes place that changes the wood so that the wood is more decay resistant, stable with moisture changes, yet easy to work with.
Acetylation of wood A review Roger M. Rowell* ... In the late 1980s in Japan, Daiken started commercial production of acetylated wood for flooring called alpha-wood. Also in the late 1980’s and early 1990’s, ACell, in Sweden, were granted many patents and built two pilot plants:
Accoya is the world's leading long life sustainable wood. With a 50 year guarantee not to rot, Accoya delivers remarkable levels of performance. Using our Acetylated Wood Modification process we convert sustainable FSC softwood into timber with the properties of hardwood.
Acetylation Process 2. What is acetylated wood? ... Residual acetic anhydride and by products of the reaction are removed from the wood; Acetylated wood is quality checked; Acetic anhydride is recycled and used in future production batches; The main by-product, acetic acid, is sold as amaterial for other industries ...
"Mechanical properties and dimensional stabilities of wood-polypropylene composites prepared using mechanochemically acetylated Japanese cedar (Cryptomeria japonica) wood meal," BioRes. 11(2), 3825-3839.
Acetylated wood is quality checked Acetic anhydride is recycled and used in future production batches The main by-product, acetic acid, is sold as amaterial for other industries
Accoya wood is a brilliant material for windows and doors as it offers improved thermal insulation in comparison with commonly used wood species and is more durable and dimensionally stable than the best tropical hardwoods.
Treating Wood with Acetylation Process Woodworking Network. 4 Oct 2010 by the University of Florida in an international competition. Acetylation changes the free hydroxyls within the wood into acetyl groups, by
Acetylated wood has the strength of regular wood that is very dry, Rowell says. For every 1% gain in moisture, wood loses about 5% of its modulus of rupture, a measurement of how a material bears a large load.
Accoya Wood Used in International Solar Decathlon Competition - 10/06/2010 University of Florida uses sustainable Accoya wood in zero-energy
To clarify the role of lignin in the affinities of acetylated wood for organic solvents, the effects of delignification on the solvent adsorption of acetylated wood were investigated. Acetylated wood meals rapidly adsorbed organic solvents that were hardly adsorbed by unmodified wood. For nonpolar ...

Chemical Modification of Wood by Acetylation or Furfurylation: A Review of the Present Scaled-up Technologies George I. Mantanis Significant developments in the area of wood modification have been achieved during the last three decades.
Furthermore, acetylated wood has credible Eco friendly and sustainable standards and accreditations such as FSC, PEFC, Singapore Green Label and Cradle to Cradle certifications. In a nutshell , the final say is still up to the home owner as what kind of wood, he or she would like to have for the balcony decks as well as other forms of woodwork ...
Acetylated wood is an alternative to conventional chemical treatments, but the company didn't see a quick enough return on its investment to continue producing it.
Acetylated Treated Lumber — What's Up with That? Here's an interesting discussion about the durability, fastener compatibility, and other properties of acetyl treated lumber, such as "Accoya," with some useful links to more. ... Acetylated wood has been studied for many decades. It has been under commercialization for over 25 years, but cost ...
For every 1% gain in moisture, wood loses about 5% of its modulus of rupture, a measurement of how a material bears a large load. “Is acetylated wood stronger?” he asks. “Yes, by quite a bit, because it is drier.” Similarly, acetylated wood resists termites partially because it is harder than unmodified wood.
Using our Acetylated Wood Modification process we convert sustainable FSC softwood into timber with the properties of hardwood. Accoya is the world's leading long life sustainable wood. With a 50 year guarantee not to rot, Accoya delivers remarkable levels of performance.
