What is Accoya?

What is Accoya?

Accoya is an acetylated form of Radiata Pine.

 General timber fibres contain an abundance of chemical groups called ‘hydroxyls’, this essentially allows general timber to absorb / release water causing the material to swell and shrink which is also one of the principal reasons that wood is prone to decay. 

 Acetylation is a non toxic process in which the pine is soaked in acetic anhydride (an organic compound related to vinegar)

 Acetylation transforms the hydroxyl groups to (also naturally occurring) acetyl groups, causing a strong reduction of water uptake making it not only dimensionally stable but also extremely durable.

Some major benefits of using Acetylated Wood (Accoya):

-               A non-toxic, fully recyclable wood

-               Outstanding durability

-               Confidence in coating

-               Dimensionally stable 

-               Wide boards

-               Improved installation efficiency 

-               Can be cut or profiled without exposing unprotected surfaces

-               A high durability achieved by stopping the rot fungi from digesting wood, not by killing them with toxins 

-               Accoya boards may be performed with trim free corners and mitre joints 

Accoya is warranted: 

50 years above ground & 25 years in ground
