Outstanding Performance

Extensive laboratory and field testing by leading institutes around the world (including in New Zealand, USA, UK, Sweden, Malaysia, Indonesia, Russia, the Netherlands and Japan) 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.

DIMENSIONAL STABILITY

- Swelling and shrinkage reduced by 75% or more
- Doors and windows open effortlessly year round
- Paints and varnishes last 3 or 4 times longer,
  greatly reducing maintenance costs

CLASS 1 DURABILITY

- The most durable wood possible
- More durable than teak and the world’s other
  most durable woods
- Perfect for outdoor use

LONG LASTING

- Lasting at least 50 years above ground and
  25 years in ground

ROT & INSECT BARRIER

- Accoya® wood is indigestible to insects and microorganisms
  and is therefore more resistant to decay
- Barrier to wood-destroying fungi
- Accoya® wood is virtually rot-proof

PERFECT FOR COATING

- Easier to coat: less preparation and sanding between
  coatings required
- Improved dimensional stability and UV resistance
  improves the life of coatings
- Perfect for transparent, translucent and opaque coatings

NATURALLY BEAUTIFUL WOOD

- The process does not compromise the wood’s natural
  beauty

NATURALLY INSULATING

- Accoya® wood offers improved thermal insulation
  in comparison with commonly used wood species
- Accoya® wood is ideal for applications where energy
  conservation is important

NON-TOXIC

- Accoya® wood is non-toxic, protecting the
  environment from the harmful effects of poisons leaching
  out of typical wood treatment
- Accoya® wood may be safely reused and recycled

FROM SUSTAINABLE SOURCES

- Sustainably sourced, including from FSC, PEFC and
  other regionally certified woods
- Naturally renewable

UV RESISTANT

- Accoya® wood has superior resistance to UV
  degradation when translucent coated and its natural
  appearance lasts longer
- Accoya® wood is the ultimate substrate and coating
  life is increased

RETAINED STRENGTH & HARDNESS

- The process does not compromise the wood’s strength
- Hardness is increased
- High strength to weight ratio, making it suitable for
  challenging applications

100% RECYCLABLE

- Fully reusable and recyclable
- Reuse is recommended but Accoya® wood may be
  safely incinerated for bio-energy or composted

CONSISTENT QUALITY THROUGHOUT

- Consistent, measurable modification quality from
  surface to core
- No need to apply chemical preservatives when cut or
  planed

MACHINABILITY

- Accoya® wood is easy to machine and process
  manually, creating no challenges for product
  manufacturers and end users

CONSISTENT SUPPLY

- Produced from abundantly available, fast-growing sources
  species such as Radiata Pine
