Accoya Wood

« Back to Glossary Index

Are you looking for a sustainable, versatile and innovative building material? Then Accoya wood might be exactly what you’re looking for. For architects, contractors, timber suppliers and sustainability-oriented homeowners, Accoya wood offers an excellent balance of quality, environmental friendliness and performance.

What is Accoya Wood?

Accoya wood is a modified timber produced through a special process called acetylation. This process, where Radiata pine (a fast-growing softwood species) is treated with acetic anhydride, changes the chemical structure of the wood.

The result? A durable, dimensionally stable and extremely weather-resistant product that revolutionizes the world of timber applications. Compared to other modified wood types, such as thermally modified wood or furfurylation, Accoya has unique advantages. For example, it retains its strength and natural appearance while delivering exceptional environmental performance.

The Properties and Benefits of Accoya Wood

What makes Accoya wood so special? Here are the key properties and benefits at a glance:

1. Top Class Durability

Accoya is classified as durability class 1, the highest possible classification that performs better than tropical hardwood. This makes it perfect for outdoor use and resistant to the harshest weather conditions.

2. Dimensional Stability

Thanks to the acetylation process, Accoya wood hardly moves. This means less shrinkage, swelling and deformation occurs, even with large temperature and humidity differences. Ideal for facade cladding and terrace projects!

3. Resistance to Rot and Fungi

With impressive resistance to rot, fungi and wood-eating insects, Accoya is a low-maintenance and reliable material, even in humid or wet environments.

4. Reduced Moisture Absorption

The acetylation process significantly reduces the moisture absorption of the wood, contributing to its stability and longer lifespan.

5. Sustainability Classifications and Certifications

Accoya wood is FSC certified and has a Cradle to Cradle Gold certification, guaranteeing that it comes from sustainable sources and has minimal environmental impact.

Applications of Accoya Wood

The versatility of Accoya wood makes it suitable for a wide range of applications, including:

Facade cladding: Thanks to its stability and durability, Accoya cladding is a popular choice for high-quality projects.

Window frames and doors: The minimal movement ensures that frames and doors maintain their shape and continue to close perfectly.

Terraces and outdoor flooring: An Accoya deck combines luxurious appearance with robust performance, even with intensive use.

Water works: Jetties, bridges and other water-related constructions benefit from the high resistance to moisture and rot.

Garden wood and outdoor furniture: Ideal for garden projects where style and functionality go hand in hand.

Accoya vs Traditional Wood Species

1. Comparison with Tropical Hardwood

While tropical hardwood is known for its durability, it has disadvantages such as deforestation and long growth cycles. Accoya offers a more environmentally friendly alternative with the same, if not better durability and performance.

2. Comparison with Untreated Softwood

Untreated softwood is often cheaper but has a much shorter lifespan and requires regular maintenance. Accoya maintains its properties without intensive treatment.

3. Performance Compared to Other Alternatives

Thermally modified wood, for example, can be more brittle, while Accoya remains strong and flexible thanks to acetylation.

Processing and Installation of Accoya Wood

Working with Accoya wood is simple and comparable to other wood species, but with some specific considerations.

Workability: Accoya can easily be sawn, sanded and planed without special tools.

Fixing: Use stainless steel screws to prevent corrosion and maintain durability.

Surface treatment: Accoya can be painted or stained and retains coatings longer due to lower moisture absorption.

Focus on Sustainability

The environmentally friendly character of Accoya wood is one of the biggest selling points. Here are the main sustainability benefits:

FSC Certification: The raw material comes from sustainable, controlled forests.

Cradle to Cradle certification: Accoya is recyclable and meets circular economy principles.

CO₂ storage: With its long lifespan, Accoya keeps more CO₂ stored than alternative wood species.

Choose Innovation, Choose Accoya

With its exceptional properties, versatile applications and commitment to sustainability, Accoya wood is the choice for contemporary building projects. Whether you’re an architect looking for sustainable facade cladding, or a homeowner with a passion for environmentally friendly materials, with Accoya you make a future-proof choice.
