Accoya wood stands as the top choice for cladding, combining low maintenance needs with industry-leading environmental and sustainability credentials. It offers performance characteristics akin to the most durable tropical hardwoods. Accoya cladding requires significantly less maintenance than other timbers. Its exceptional stability ensures tight tolerances and minimal distortion, even with wide boards, providing architects and specifiers unparalleled design flexibility.






Depending on your desired asthehtic there are two choices when at the beginning stage of specifying Accoya cladding:
‘Natural’ Accoya is blonde, clear pine board which can be finished with your desired protective coating.
‘Grey’ Accoya is coloured through completely from surface to core. No coating necessary, ever.
