Thus, it is an ideal choice both in architectural projects and in terms of environmental responsibility. Tests Conducted by BM TRADA Durability with Exceptional Performance Superior Stability Leading wood research institute BM Trada cyclically exposed coated boards to wet and ambient conditions to assess Accoya’s stability. The tests found that Accoya has exceptional dimensional stability and that the cladding can be expanded from standard 150 mm wide profiles to 200 mm. These results prove that Accoya offers more flexible design options and stands out with its superior performance compared to other types of wood. Coating Performance BM Trada compared Accoya cladding with pine and Siberian larch in a series of durability tests launched in Buckinghamshire, England in February 2007. The same translucent black coating was used to ensure maximum radiant heat generation and to test resistance to natural weathering. After 3.5 years of testing, Accoya was found to have superior performance compared to pine and Siberian larch. While pine cladding showed cracking, resin leakage, paint peeling and surface deterioration, Siberian larch showed resin pockets and surface deformation. Accoya maintained its durability without any swelling, cracking or paint peeling on its surface. It was proven that external dirt can be easily cleaned, providing a durable and clean surface. These tests clearly demonstrate that Accoya has superior cladding performance compared to competing materials. Catalogs Superior Durability Assessed by BRE Although BS EN 350-2 does not apply to modified timber, Accoya has achieved Durability Class 1, the highest level for natural timber, in an assessment by BRE. Accoya therefore meets the service life criteria set out in the BS 8417 standard, fully complying with the 60 year designed service life requirements that only timbers with Durability Class 1 certification are eligible for. This superior durability demonstrates that Accoya offers a long-lasting and reliable timber solution. Contact Guarantees Accoya offers long-lasting performance with a warranty period of over 50 years in exterior cladding. It provides an aesthetic and sustainable solution thanks to its high resistance to decay and deformation.

Extremely Durable Accoya claddings do not contain toxic substances or harmful chemicals. FSC® certified, it offers an eco-friendly solution made from sustainable wood. A Stunning Experience Summer House with Charred Accoya Exterior Cladding Delta Millworks, located in New York, produced a unique four-season summer house exterior cladding using Accoya. The Accoya wood supplied by Universal Forest Products was charred using the traditional Japanese “Shou Sugi Ban” method, giving the façade a modern and weathered texture. This technique created a striking and deep visual effect. Delta discovered that the charred Accoya developed superior density and durability compared to other wood types. Accoya’s natural dimensional stability combined with charring created a strong foundation for long-lasting performance. DECkING SIDING DOORS & WINDOWS INSPIRING PROJECTS

Features Above Ground 50 Year Warranty Acetylated wood is the main ingredient of Accoya and is a special chemical treatment that increases the durability, stability and resistance to decay of the wood. The acetylation process changes the cellular structure of the wood, reducing its ability to absorb water and providing superior resistance to biodegradation. Tree scientists have been researching and testing the effects of this process in detail for many years. Studies have shown that acetylated wood has a much longer lifespan than traditionally treated wood. Acetylated wood has been documented to perform particularly well in exterior applications—such as cladding, window and door systems, marine structures, and other wood elements exposed to harsh weather conditions. See Warranty Test Results Trada & Bre Accoya’s superior durability has been proven by scientific tests and is directly comparable to other types of wood. Tests carried out in European standards to determine the resistance of wood to decay clearly demonstrate Accoya’s performance compared to its competitors. The most important of these tests is the EN 113 standard, which assesses the resistance of wood materials to biodegradation and fungal decay. Accoya achieved the highest level of resistance in these tests, exceeding even tropical hardwoods. This success has been confirmed by the independent research organisations BRE (Building Research Establishment) and TRADA (the UK’s leading independent wood research association). This superiority of Accoya is directly related to the fact that the acetylation process changes the molecular structure of the wood. Acetylated wood gains a natural immunity to rot and fungal attacks, while its water absorption rate is significantly reduced. This not only increases durability, but also maximizes the dimensional stability of the wood. In line with this scientific data and long-term field tests, Accoya is now offering a 50-year warranty, unprecedented in the wood sector, thus confirming its confidence in its durability. Promising long-lasting performance in outdoor applications and even in the harshest climatic conditions, Accoya continues to be a pioneer of sustainable and high-quality wood solutions. Projects Under the Ground 25 Year Warranty Accoya wood is one of the most reliable wood solutions preferred in modern construction and design projects with its unique features and long-term warranty conditions. Modified with the acetylation process, Accoya has a much longer life than ordinary wood types and offers high durability. Thanks to these superior qualities, it meets expectations at the highest level both aesthetically and functionally. One of the most striking features of Accoya is that it offers a unique warranty period of 25 years underground or in fresh water and 50 years in outdoor applications. While traditional wood types become vulnerable to decay, fungal growth and pest attacks over time, Accoya eliminates these risks and provides long-lasting use.

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.
