What Is Accoya?

This modified wood is sustainably sourced with FSC® certification and it has minimal environmental impact throughout its entire life; from production, through its use, right the way to the end of its life.

Accoya is wood.

Right, ok.

So why have you never heard of the Accoya tree?

Well that’s because they don’t exist. Accoya starts life as a fast-growing pine tree (Pinus radiata) grown in managed forests. The pine tree is harvested once it reaches maturity at around the 30 year mark. It’s at this point its journey isn’t the same as other timber. We introduce the raw timber to a modification process as a plank or beam, the so-called acetylation process using acetic acid. Read more about acetylated wood here. This process creates extremely dimensionally stable and durable wood.
