Above Ground
50 Year Warranty
Acetylated wood is the main ingredient of Accoya and is a special chemical treatment that increases the durability, stability and resistance to decay of the wood. The acetylation process changes the cellular structure of the wood, reducing its ability to absorb water and providing superior resistance to biodegradation. Tree scientists have been researching and testing the effects of this process in detail for many years.
Studies have shown that acetylated wood has a much longer lifespan than traditionally treated wood. Acetylated wood has been documented to perform particularly well in exterior applications—such as cladding, window and door systems, marine structures, and other wood elements exposed to harsh weather conditions.
Test Results
Trada & Bre
Accoya’s superior durability has been proven by scientific tests and is directly comparable to other types of wood. Tests carried out in European standards to determine the resistance of wood to decay clearly demonstrate Accoya’s performance compared to its competitors. The most important of these tests is the EN 113 standard, which assesses the resistance of wood materials to biodegradation and fungal decay. Accoya achieved the highest level of resistance in these tests, exceeding even tropical hardwoods. This success has been confirmed by the independent research organisations BRE (Building Research Establishment) and TRADA (the UK’s leading independent wood research association).
This superiority of Accoya is directly related to the fact that the acetylation process changes the molecular structure of the wood. Acetylated wood gains a natural immunity to rot and fungal attacks, while its water absorption rate is significantly reduced. This not only increases durability, but also maximizes the dimensional stability of the wood. In line with this scientific data and long-term field tests, Accoya is now offering a 50-year warranty, unprecedented in the wood sector, thus confirming its confidence in its durability.
Promising long-lasting performance in outdoor applications and even in the harshest climatic conditions, Accoya continues to be a pioneer of sustainable and high-quality wood solutions.
Under the Ground
25 Year Warranty
Accoya wood is one of the most reliable wood solutions preferred in modern construction and design projects with its unique features and long-term warranty conditions. Modified with the acetylation process, Accoya has a much longer life than ordinary wood types and offers high durability.
Thanks to these superior qualities, it meets expectations at the highest level both aesthetically and functionally. One of the most striking features of Accoya is that it offers a unique warranty period of 25 years underground or in fresh water and 50 years in outdoor applications. While traditional wood types become vulnerable to decay, fungal growth and pest attacks over time, Accoya eliminates these risks and provides long-lasting use.
