Accoya® timber solutions for modern and minimalist facades

Accoya is a modified timber that offers exceptional performance for exterior cladding and the only wood that offers 50 years warranty. It’s engineered to last, providing stability and durability in all weather conditions.

What makes Accoya® different?

Accoya isn’t just another timber option- it’s a game changer in modern architecture. This specialised wood starts as high-quality, sustainably grown softwood and undergoes an advanced acetylation process. In simple terms, this treatment transforms the wood at a molecular level, making it exceptionally stable. Unlike traditional timber, which swells and shrinks when exposed to moisture, Accoya remains dimensionally stable. This means fewer gaps, tighter joints, and a flawless finish – perfect for contemporary designs that demand precision.

Longevity, design flexibility & sustainability

Accoya stands out for its proven longevity, backed by warranties for both above-ground and below-ground applications. Unlike traditional timber treatments that leach chemicals over time, Accoya’s durability is inherent to its molecular modification. This stability opens up new design possibilities meaning your build can confidently use large panels and intricate detailing without the risk of warping or movement. The timber can be machined and finished with precision, providing versatility across a range of finishes, including natural timber, silver-grey weathered tones and factory-painted options. Beyond performance, Accoya is sourced from sustainable forests and manufactured with low environmental impact, making it an eco-conscious choice for your next project.
