ABOUT ACCOYA
Why use Accoya? Accoya® wood represents a major development in wood technology. It enables the consistent supply of durable, non-toxic, dimensionally stable wood. This makes it an ideal material for manufacturing high performance, exterior timber products like wood siding and outside decking. Accoya is manufactured through the acetylation of plantation grown softwood. For over 80 years this has been the gold standard in the academic field of wood science. A breakthrough in close-loop engineering, culminating in 2007, led to the first commercial scale production of the product in the world.
Accoya should be specified in conjunction with the large number of companies manufacturing cladding, decking, landscape timbers and joinery using Accoya wood.
Looking to the future, we will strive to retain our strong sustainability position and further improve Accoya wood's outstanding environmental performance. With our environmentally sound production process in place and the continuous improvements we make, we are confident that Accoya will remain a world leader in sustainable wood technology.

OUTSTANDING PERFORMANCE
Extensive laboratory and field testing by leading institutes around the world ( including in New Zealand, USA, UK, Sweden, Malaysia, Indonesia, the Netherlands and Japan ) has shown the performance of acetylated wood to be extremely reliable.
Accoya® treated wood has been throughly tested for dimensional stability, durability, 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 modified timbers are measured.

ACCOYA® WOOD DECKING
ACHIEVE A BEAUTIFUL ALL WEATHER, LOW MAINTENANCE DECK WITH ACCOYA®
When deciding what timber to use for outdoor decking materials; beauty, strength, sustainability and all-weather decking performance are important. Accoya® wood embodies the beauty of natural wood with exceptional performance characteristics. Selecting a dimensionally stable material for outdoor decking is essential to ensure the timber used for decking will stay flat and not warp, split, swell or be affected by fungi, water uptake or rot. It is also crucial that your decking materials is non-toxic and therefore totally safe for people and pets. Accoya® decking, meets every one of these exacting requirements. All of its features combined mean that Accoya® produces both a long-life and low maintenance decking solution which few other decking materials are able to offer.
Accoya® wood is proven to deliver outstanding results as timber for decking in a wide range of decking projects from around the world. It can be machine profiled to suit the project specifications and comes with a 50 year warranty against rot and decay. Accoya® wood has enhanced resistance against UV light and comes with enhanced coatings performance which can last up to 3-4 times longer.

INSECT DECAY
Accoya® wood is indigestible to a wide range of pests and an effective barrier to attack. For example, testing for termites according to AWPA E1 test standards yielded appearance ratings always ≥ 9 (Light Attack) versus control sample averages of 3.5 (worse than Heavy Attack). Weight loss averaged only 1.43% for Accoya® wood versus control sample averages of 32.06%.
MACHINABILITY
Processing does not affect the unique properties of Accoya® wood, as it is modified throughout and not leachable. It is relatively easy to process and can be compared to profiling a soft wood species. No special tools are required for cross cutting, ripping, planing, routing and drilling. Sanding before finishing is rarely required.
GLUING
Both load bearing and non-load bearing applications have been tested using adhesive systems related to laminating, finger jointing and frame corner joints. While good results can be achieved with most common adhesives, PU, epoxy and PRF adhesives give the best results. The results of gluing with polyvinyl acetate (PVAc) and melamine urea formaldehyde (MUF) can vary greatly. Specific recommendations for your project are available upon request.
FINISHING
Most commonly used coating systems can be used on Accoya® wood. Testing has been performed with a full range of oilbased and water-based coating systems. Leading coating manufacturers have found that their products last three or more times longer when used on Accoya® wood. Specific recommendations for your project are available upon request.
FASTENING
In good joinery practice, the use of corrosion-proof steel fastenings that conform to EN 10088-1 is recommended such as A2, A4 quality stainless steel. Use of other metals and alloys is included in the Accoya® Wood Information Guide.

PLYWOOD
Plywood is a popular choice for residential and light-duty construction and is made from thin sheeets of veneer that have been peeled from debarked wood. These thin layers, also called plies, are glued together in alrernating, perpendicular directions to create a cross-graining pattern. This pattern results in added strength and stability that resists shrinkage and expansion.
