Tried and Tested Accoya has thoroughly been tested for dimensional stability, durability, paint retention and in-ground conditions, Accoya 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.
In contrast to other modification techniques, it is possible to measure the quality of Accoya by determining the acetyl content of the wood, once it has been modified by measuring the percentage of acetyl groups present. Using an array of analytical techniques, Accoya’s producers ensure that every batch is of consistent quality and reaches the highest performance standards.
With such strong scientific credentials, Accoya is guaranteed for 50 years when used above ground, and 25 year when used for below-ground and freshwater applications.
