    About Accoya Wood

    Accoya wood’s durability makes it very long lasting, at least:
    - 50 years above ground
    - 25 years in-ground or freshwater contact

    Accoya wood forms an effective barrier to mold and insect attack; it is indigestible to microorganisms and insects and therefore more durable to wood-destroying fungi and virtually rot-proof.

    Extensive laboratory and field testing by leading institutes around the world has shown the performance of acetylated wood to be extremely reliable. Accoya® wood has been thoroughly tested for dimensional stability, durability, UV resistance, paint retention and in-ground conditions to ensure optimal performance. Indeed, it is so reliable that for many years it has been – and continues to be – used by scientists as the benchmark against which other treatments and modifications are measured.
