What is Accoya® wood?

 

Accoya® is the result of more than 75 years’ research and development that have brought together a long-established and extensively researched wood modification technique, acetylation, and leading-edge technology to create and make this extraordinary “new wood” commercially available for the first time.

Accoya® is set to become the material of choice for exterior applications and can be used for virtually anything, from windows to doors, decking to cladding and even for applications which are presently the preserve of non-sustainable materials.

Accoya® is perfect for outdoor use, with the performance of the best tropical hardwoods and much more besides:

  • Class 1 durability - the best available
  • Outstanding dimensional stability which dramatically improves coatings adhesion and product performance
  • Lasting for 50 years above ground and 25 years in-ground
  • Environmental compatibility - non-toxic, 100% recyclable and sourced from sustainable forests
  • Consistent, measurable quality all the way through the wood, not just at the surface
  • Retained natural strength and beauty, increased hardness
  • Consistent supply from sustainably managed forests and plantations
  

 
 
 
 

The Acetylation Process -

 

1. Rough sawn sustainable wood is soaked in acetic anhydride

2. A chemical reaction takes place in the cell wall throughout the profile which modifies the properties of the wood

3. Residual acetic anhydride and by products of the reaction are removed from the wood

4. Acetylated wood is quality checked
  
 
 
 
 

•Only naturally occurring wood compounds are added to the wood
•Result is a non-toxic, fully recyclable wood
•Modifies the wood to its core
•Unlike biocide impregnation
•Can be cut or profiled without exposing unprotected surfaces
•The acetylation process is irreversible
•No risk of leaching/loss
•Permanent improvement in performance
•Acetylation changes wood at the molecular level
•Durability is achieved by stopping the rot fungi from digesting wood, not by killing them with toxins
