Accoya® turns everything you know about wood on its head. Through a revolutionary scientific process called acetylation, it modifies wood to give it properties above and beyond the very best hardwoods – and in many cases, aluminum and PVC.

Accoya® has been selected by hundreds of manufacturers as their wood of choice and used on some of the most architecturally significant projects in the world. Its unparalleled credentials make it the ideal material for windows, doors, shutters, decking, siding and much more.

Why Accoya®?

  • Unprecedented reliability for lumber – it is checked and trusted not to visibly swell, shrink or distort
  • 50 year above ground, and 25 year in ground or freshwater warranty
  • Coatings and finishes look brilliant and last longer, resulting in hassle-free care while saving time and money long-term
  • Huge design freedom with the ability to create a multitude of textural finishes such as smooth, charred and brushed
  • Accredited by the FSC® and Cradle to Cradle Gold certified™, it is the only construction material in the world to achieve C2C Platinum certification™ for Material Health
  • Non-toxic, making it safe for people and pets as well as the planet


Tricoya® is a completely new, high performance, medium density fiberboard (MDF) panel product. It uses a proprietary acetylated wood technology and a modified MDF manufacturing process to create a wood panel product with outstanding durability and dimensional stability, even in the most extreme and challenging environments - both exterior as well as interior, wet and high moisture applications.

Why Tricoya®?

Can be cut, coated, sanded, glued, machined and fastened the same as any other high performing wood fiberboard, allowing users all the freedom associated with MDF.

  • Highly durable and longer lasting, perfect for outdoor use or wet interior environments
  • 50 year above ground, and 25 year in ground warranty
  • Dimensionally stable – swelling and shrinking dramatically reduced
  • Sustainably sourced FSC® certified
