Accoya Wood: A Sustainable Solution for Modern Building Needs

Accoya Wood: A Sustainable Solution for Modern Building Needs

Accoya Wood is a top choice for builders and architects worldwide with its innovative properties, eco-friendly profile, and the assurance of a 50-year warranty. In today's construction landscape, sustainability and performance are paramount. The numerous benefits and applications of Accoya Wood are examined here, showcasing its ability to meet modern building needs while also promoting environmental stewardship.

What is Accoya Wood?

Accoya Wood is created through a revolutionary wood modification process called acetylation. This technique enhances the natural qualities of softwood by altering its cell structure, significantly increasing its durability and stability. Unlike traditional wood treatments that use toxic chemicals, acetylation employs naturally occurring compounds to improve performance, making it safe and sustainable.

The Benefits of Accoya Wood

Unmatched Durability. Accoya is exceptionally durable. The acetylation process makes it highly resistant to rot, decay, and insect damage, allowing structures made from this wood to withstand harsh weather conditions for decades with minimal maintenance. Tested to last 50 years above ground and 25 years in-ground or freshwater contact, outperforming all other traditional wood species.

Dimensional Stability. This material is known for its superior dimensional stability, meaning it does not warp, swell, or shrink even under extreme temperature and humidity changes. Therefore, it is ideal for applications requiring precision and consistency, such as window frames, doors, and cladding. Additionally, it performs exceptionally well in diverse climates, from the low humidity of Arizona to the high humidity of Miami.

Sustainability. Accoya is sourced from fast-growing, FSC sustainably managed forests, primarily radiata pine. The environmentally friendly acetylation process enhances the wood without harmful chemicals. Fully recyclable and biodegradable, Accoya Wood aligns with circular economy principles, reducing the carbon footprint of construction projects and promoting a greener future. Furthermore, Accoya's "Cradle to Cradle" certification underscores its commitment to sustainable and responsible production.


Whether enhancing the exterior of a modern building or providing a safe, long-lasting surface for outdoor spaces, Accoya Wood delivers unmatched performance and low maintenance requirements.

  • Ensures buildings remain beautiful and functional for decades
  • Easily painted or stained
  • Provides versatile design options for architects and builders

Accoya Wood Decking

  • Offers unparalleled performance for outdoor spaces
  • Does not warp or splinter like traditional decking materials
  • Stays smooth and stable, providing a safe, attractive surface
  • Ideal for patios, balconies, and boardwalks
  • Resistant to moisture and decay, perfect for wet environments (e.g., poolside areas, waterfront properties, and docks)
  • Low maintenance, requiring only periodic cleaning

Bridges and Walkways

Accoya Wood's exceptional durability and resistance to moisture make it an ideal choice for bridges and walkways, particularly in environments where exposure to water and humidity is a concern. Its dimensional stability ensures that the wood does not warp, swell, or shrink, maintaining structural integrity over time. This makes Accoya an excellent material for pedestrian bridges and boardwalks in parks, nature reserves, and coastal areas.

Environmental Impact and Certifications

Accoya's eco-friendly status is validated by several significant environmental certifications, providing builders and consumers with confidence in its sustainability:

Forest Stewardship Council (FSC) Certification. Ensures responsible sourcing from managed forests.

Cradle to Cradle Gold Certification. Recognizes its contribution to a circular economy and minimal environmental impact.

Nordic Swan Ecolabel. This certification signifies that Accoya meets strict environmental standards throughout its lifecycle, from production to disposal. It's a trusted symbol for environmentally responsible products in Nordic and European markets.

Comparing Accoya Wood to Other Building Materials

Accoya Wood stands out when compared to other building materials:

Environmental Impact vs. Composite Materials. Composite materials, often made from wood fibers and plastic, have significant environmental impacts during production and disposal. Accoya Wood, fully recyclable and sourced from renewable forests, is a more eco-friendly alternative.

Cost-effectiveness vs. High-end Materials. High-end materials like tropical hardwoods offer durability and aesthetics but come with high environmental costs due to deforestation and transportation. Accoya Wood provides comparable performance at a lower environmental and financial cost, making it a smart choice for sustainable building.

Real-World Examples

Accoya Wood has been used in numerous high-profile projects worldwide:

The University of Alberta Botanic Garden. Features a new Welcome Center with Accoya wood siding, which includes ticket booths, a gift shop, restrooms, and a large outdoor canopy designed to host various functions. Inspired by a tree and shaped like a fallen leaf, the pavilion's design complements the garden's natural beauty while providing shade and shelter to visitors. This structure exemplifies the sustainable and aesthetic benefits of using Accoya wood in construction projects.

New Pilarín Bayés Library in Vic, Barcelona. Designed by BCQ Arquitectura Barcelona studio, this modern space offers traditional reading, consultation, and study areas, alongside a children's area, music rooms, social spaces, and a gaming area. Completed with a double façade made of Accoya wood, the library allows natural light to fill the interior and offers views of the surrounding trees, garden, and old town. Accoya was selected for its natural look, durability, stability, and sustainability, highlighting how Accoya combines sustainability and aesthetics in contemporary architectural projects.

Installation and Maintenance Tips

To maximize lifespan and performance, proper installation and maintenance are key:

Installation. Follow manufacturer guidelines, use stainless steel or coated fasteners to prevent corrosion, and ensure proper ventilation to minimize moisture buildup.

Finishing. Wood can naturally weather to a gorgeous silver color over time. Alternatively, applying a finish can enhance its appearance and provide additional protection. For the best results, use high-quality paints or stains that are compatible with acetylated wood.

Maintenance. Requires minimal upkeep. Regular cleaning with mild soap and water is usually sufficient. Periodically inspect for damage or wear and address any issues promptly.


Accoya Wood is revolutionizing the construction industry with its combination of durability, stability, and sustainability. From siding and cladding to decking and structural applications, this innovative material meets modern building demands while promoting environmental responsibility. By choosing Accoya Wood, builders and architects can create beautiful, long-lasting structures that contribute to a greener future. Embrace Accoya Wood for your next project and experience firsthand the benefits of this sustainable solution.
