Tricoya (part of Accsys) is a modified wood timber technology company offering several advantages over conventional wood.

Tricoya's key features:

  • Process: Tricoya utilizes a proprietary acetylation process that chemically modifies wood fibers at a molecular level.
  • Benefits: This process enhances the following properties of the wood:
    • Durability: Significantly increases resistance to rot, decay, and insect infestation, allowing for longer lifespans compared to untreated wood.
    • Dimensional Stability: Reduces swelling and shrinkage due to moisture fluctuations, making it suitable for exterior applications.
    • Fire Resistance: Offers improved fire retardancy properties.
  • Applications: Tricoya is primarily used in various exterior and high-moisture environments due to its enhanced durability and stability.
    • Examples include:
      • Doors and windows
      • Cladding and facades
      • Decking and outdoor furniture
      • Soffits and fascias


  • Tricoya emphasizes their commitment to sustainable practices:
    • Uses wood sourced from sustainably managed forests certified by independent organizations.
    • The acetylation process utilizes acetic acid derived from renewable sources like wood.
    • Offers a longer lifespan for wood products, reducing the need for frequent replacements.
