Accoya Lumber - In Stock!

We are proud to announce that we are now a distributor for Accoya! Alongside the Alan McIlvain Company on the East Coast, we will be expanding the market for the new Tennessee production of Accoya lumber. That's right, in 2024 Accoya added a new proprietary acetylated wood manufacturing facility in Kingsport, Tennessee for the North American market. As the US seeks more sustainable building materials, there is a burgeoning market for high performance wood. 

What is Accoya Lumber?

"WOOD TO CHANGE THE WORLD" - Accoya is a revolution in modified dimensionally stable wood, delivering remarkable levels of performance. A product made to last: warrantied for 50 years above ground, and a 25 years in ground or freshwater warranty.

Fast-growing, certified sustainable Radiata Pine is transformed into Accoya wood through a proprietary acetylation process. The result is high performing sustainable lumber with sustainability credentials that exceed those of man-made, intensely resource depleting and heavily carbon-polluting alternatives. This gives the world the choice to build sustainably, offering new opportunities in sustainable building materials.

What is Acetylation?

Treating or modifying wood by subjecting a softwood to a vinegar, which turns it into a hardwood by preventing the cells in the wood from being able to absorb water. So acetylated wood is… Pickled wood? More or less. Yes.

Acetic anhydride, a really strong vinegar in its concentrated form, interacts with the wood to make the wood molecules resistant to binding with water. And, the liquid left over really is just strong vinegar. Accoya can even send this by-product out to be used in other industries, or reprocess it so to use it again.

Treating or modifying wood by subjecting a softwood to a vinegar, which turns it into a hardwood by preventing the cells in the wood from being able to absorb water. So acetylated wood is… Pickled wood? More or less. Yes.

To understand the benefits of using acetylated timber, we will point out the importance of acetylated wood not absorbing water. When making anything out of wood, its water that’s the main trouble maker.
Keep wood dry and well maintained and it’s one of the greatest materials of all time. But introduce water, and problems begin to seep in. With untreated, badly treated or unmodified wood, water can bring a whole host of problems including rotting, warping, splintering, swelling, shrinking and being food for hungry insects.
So acetylation wood technology removes the issue at source; rather than treating wood with a toxic chemical trying to stop rot or insect attack and not helping with other water issues. The result is real wood that doesn’t rot. It doesn’t warp, swell or shrink. It doesn’t splinter, and it isn’t termite food. In fact, removing all these traditional issues means that acetylated wood presents even more benefits than just ‘not failing’. It is so dimensionally stable (maintains its original shape and dimensions) that it’s perfect for coating and has outstanding durability. This wood, Accoya®, is acetylated wood, the only acetylated wood.
No longer at risk of traditional wood failure gives you confidence of longevity. Meaning any deck, cladding, windows or doors, boat, desk, fence, shed, sculpture, or whatever else you want to make, it’s going to last so much longer than any traditional alternative. So Accoya® is an investment in the future.  No water. No movement. No problem!
