Accoya

Accoya

Natural wood. Performance, precision, and a lifetime of durability.

Accoya is a sustainably modified wood that delivers unmatched stability, durability, and environmental performance.

  • Unmatched Durability: Guaranteed for up to 50 years above ground, Accoya resists rot, decay, and insect damage even in the harshest conditions.
  • Exceptional Stability: The acetylation process virtually eliminates swelling, shrinking, and warping for precision performance in any climate.
  • Superior Finish Retention: Holds coatings and finishes up to twice as long, reducing maintenance and preserving a refined appearance over time.
  • Sustainably Sourced: Made from FSC®-certified renewable wood and modified through a non-toxic process that enhances longevity without harming the environment.
  • Low Maintenance, High Value: Long life span and minimal upkeep translate into significant savings and enduring design integrity.

Accoya represents a new generation of wood. Real timber is transformed through an innovative acetylation process that enhances its natural structure at the molecular level. The result is a stable, durable, and sustainable building material that performs beyond even the most durable hardwoods.

Thanks to its dimensional stability and resistance to moisture, Accoya is ideal for applications where precision and longevity are critical, such as cladding and decking. It holds finishes exceptionally well, allowing for rich colors and textures.

Accoya is sourced from fast-growing, responsibly managed forests. Its non-toxic, fully recyclable composition and carbon-efficient production make it one of the most sustainable wood products available today.

Overview of the Species

Accoya is a distinct modified wood product crafted from sustainably sourced softwood that has been treated through a specialized acetylation process. This modification significantly enhances the material's dimensional stability and consistency when compared to traditional, unmodified wood options. The result is a high-performance material designed to meet the rigorous demands of professional architectural specifications.

Common Uses and Applications

This species is frequently specified for applications where precision and predictability are paramount requirements. It is widely utilized in both exterior and interior settings, serving as a reliable choice for cladding, decking, windows, and doors, as well as intricate architectural elements. Its versatility allows it to function effectively in areas where other materials might struggle to maintain their form.

Appearance and Grain Characteristics

Accoya presents a highly uniform appearance with minimal variation, distinguishing it from species that exhibit wild or unpredictable grain patterns. This visual consistency makes it particularly suitable for contemporary and modern designs that require a clean and cohesive aesthetic. The material provides a sophisticated canvas that aligns well with precise architectural visions.

Performance and Material Properties

The material is valued across the industry for its exceptional reliability, particularly when installed in demanding environments. The acetylation process ensures that the wood maintains tight tolerances, reducing the risk of movement often associated with organic building materials. This inherent stability offers architects and builders confidence that the product will perform as intended.

Working With This Species

Despite its advanced modification, Accoya can be processed using standard woodworking tools and established techniques. Builders and fabricators can mill, cut, and join the material without the need for specialized machinery, allowing for seamless integration into existing manufacturing and construction workflows.

Aging, Weathering, and Long-Term Appearance

When left unfinished, the material weathers in a manner similar to other natural wood products. Over time, exposure to the elements will cause the surface to naturally evolve, eventually developing a weathered patina. This characteristic allows the material to settle into its environment while retaining the structural benefits imparted by the modification process.

Is This Species Right for Your Project?

This material is an optimal selection for projects demanding high levels of dimensional stability and a consistent, modern visual character. It is best suited for specifications where long-term reliability is critical, offering a solution that bridges the gap between natural timber beauty and engineered performance. If your design requires a product that upholds tight tolerances in both exterior and interior applications, Accoya merits serious consideration.

Frequently Asked Questions

Is Accoya suitable for high-performance exterior cladding applications?
Yes. Accoya is exceptionally durable and dimensionally stable, making it a premier choice for exterior cladding. Its acetylation process ensures it resists rot, swelling, and warping, delivering consistent performance even in harsh or humid climates where traditional timbers may fail.
What distinguishes Accoya wood from standard softwoods?
Accoya is radiata pine that has undergone a non-toxic acetylation process. This modification significantly enhances the wood’s durability and stability while increasing its resistance to decay, effectively transforming a softwood into a high-performance building material.
What is the expected service life of Accoya?
Accoya is engineered for longevity, carrying a 50-year warranty for above-ground applications and a 25-year warranty for in-ground or freshwater contact. This extended service life makes it a reliable material for projects requiring long-term structural integrity.
How does Accoya compare to Western Red Cedar?
While Western Red Cedar offers a classic natural aesthetic, Accoya provides superior dimensional stability and a longer lifespan. For architectural projects where minimizing movement and maintenance is a priority, Accoya is often the preferred specification.
Is Accoya considered a sustainable building material?
Absolutely. Accoya is FSC® certified and sourced from fast-growing, sustainably managed pine forests. The acetylation process is environmentally responsible, resulting in a non-toxic product that aligns with green building standards.
Does Accoya require frequent maintenance?
Accoya requires significantly less maintenance than traditional wood species. Because it absorbs minimal moisture and remains stable, applied finishes (such as paints and stains) are not subjected to the expansion and contraction that typically causes peeling, extending the maintenance intervals.
Can Accoya be custom milled for specific architectural profiles?
Yes. Accoya machines with the ease of traditional wood, allowing for precise custom milling. It is ideal for executing complex profiles and intricate architectural detailing.
