Accoya turns everything you know about wood upside down. The benefits of Accoya mean that wood projects can now be designed with absolute confidence. whaT IS ACCOYA? Redefining the World of Wood Accoya is a modified wood type that stands out with its superior durability and dimensional stability. Thanks to the acetylation process, it gains maximum resistance to decay, swelling, and shrinkage. This innovative process turns Accoya into a longer-lasting and low-maintenance material compared to traditional wood species. The Most Durable and Stable The Best Wood in the World Accoya wood is produced in the city of Arnhem, the Netherlands, in a high-tech facility using fast-growing and certified sustainable timber. Modified through acetylation technology, this unique wood achieves exceptional durability and dimensional stability, making it a superior alternative to traditional materials. Compared to energy- and resource-intensive materials, Accoya is a low-carbon solution that maintains high performance with minimal environmental impact. Its long service life and resistance to decay, swelling, and deformation make it a reliable material for long-term projects. Accoya is certified for sustainability and performance, making it a strong and responsible choice for architects and designers worldwide. Lifetime Use Why Choose Accoya Wood? Since its launch in 2007, Accoya has been a trusted choice by manufacturers worldwide. From windows and doors to decking, cladding, and outdoor furniture, Accoya has been used in a wide range of demanding applications. Thanks to its durability and high performance, it stands out in architectural wood applications and extreme conditions. Its long lifespan and eco-friendly features make Accoya the ideal sustainable wood solution. Çapa 1 ACETYLATION PROCESS How Does the Modified Wood Process Work? 1 Hydroxyl Groups Wood's Water Sensitivity Natural wood contains water-attracting hydroxyl groups, which cause swelling and shrinkage. Over time, this leads to deformation and reduced durability. 2 Acetyl Groups Natural Water Resistance By replacing hydroxyl groups with acetyl groups, wood becomes more water-resistant and stable, reducing the risk of swelling and rot. 3 Acetylation Chemical Transformation for Moisture Resistance Wood is treated with acetic anhydride, which chemically changes its structure to enhance moisture resistance, minimize swelling, and extend lifespan. 4 Acetylated Wood Maximum Durability & Sustainability Accoya retains the same elements as natural wood but with increased acetyl content, resulting in outstanding durability, minimal maintenance, and superior dimensional stability. Acetylated Wood Accoya The Foundation of Superior Durability Accoya gains exceptional durability, dimensional stability, and high resistance to decay compared to traditional wood through an innovative modification process called acetylation. This advanced technology strengthens the wood’s cellular structure permanently, minimizing swelling, shrinking, and deformation. Thanks to this innovative process, Accoya becomes a long-lasting wood solution backed by a 50-year warranty. Additionally, it stands out as an eco-friendly building material since it is produced from FSC® certified sustainable sources and contains no toxic substances. Developed with acetylation technology, Accoya sets a new standard in the construction industry in terms of sustainability, durability, and low maintenance requirements.

The owners wanted to build a sustainable home that took advantage of its hilltop location, and the structure was designed to open up in three different directions, offering impressive views of the sea and Dungeness headland. The architects, who wanted to use environmentally friendly and weather-resistant materials for the project, chose Accoya wood, which stands out for its high durability and sustainability. Accoya is known in the architecture industry as a reliable material with a long-lasting and stable structure. Caspar Rodgers from Alma-nac explains their choice as follows: “We chose Accoya because we wanted to build with an environmentally friendly material that is resistant to changing weather conditions. Accoya is known in the industry as a highly sustainable product that offers high durability and stability, so it was the ideal material for us.” The exterior windows, window sills and doors in the project are made of Accoya wood. A total of 38 fixed and opening Accoya windows and 22 glazed door wings were installed. Accoya's special acetylation process makes the wood extremely durable, stable and long-lasting, ensuring that the doors and windows require minimal maintenance for years. Thanks to these superior performance features, Split House stands out as both an aesthetic and sustainable structure. The Hague, Netherlands Accoya Wood at the American School of The Hague - 7 Years Later The American School of The Hague, located in The Hague, Netherlands, was originally a 16th-century farmhouse that was transformed in 2014 into a modern school complex that offers a comfortable learning environment for approximately 250 children aged 0-6. In this transformation, Accoya wood was used not only in the façade, wooden windows and doors, but also in the roofs and wooden substructures of the old barn. In this way, a strong architectural connection was established between the historic farmhouse and the modern school structure. Rotterdam-based Kraaijvanger Architects worked meticulously to create this synergy, achieving the best balance between sustainability and the environment in their third project using Accoya wood. The classrooms are positioned on a sloped site so that the children can benefit from maximum daylight. When we revisited the project in the summer of 2021, we were faced with a school complex that had matured naturally and become more beautiful over time. The building facade, which was initially vanilla in color, turned into a platinum silver tone thanks to the unprotected (unpainted) installation of Accoya wood, giving the project an aesthetic depth. On the other hand, the windows and doors were protected with a transparent coating, increasing their durability. La Paz, Baja California Sur – Mexico Maritime Themed Architecture and Use of Accoya Baja Club is a 32-room lifestyle hotel designed for hotel group Grupo Habita, located in the historic center and coastline of La Paz, Mexico. The architectural design of the hotel features maritime-inspired details. The horizontal fluid form and curved partition elements in the newly built structure are complemented by Accoya wood cladding, reinforcing the maritime concept. The 3623 m² project involves the restoration and re-use of a colonial-style villa dating back to 1910, combined with a newly built four-story annex and basement. The new structure reflects the villa’s L-shaped floor plan, creating a harmonious architectural unity surrounding a central courtyard. 20 m³ of Accoya wood was used in the project, designed by Max von Werz Architects and supplied and installed by INNTEC Group. Accoya’s long-lasting, sustainable and aesthetic structure perfectly complements Baja Club Hotel’s architectural concept, which blends modern and historical elements.
