Yes. Accoya wood siding stands out for its remarkable performance in every climate – from humid coastlines to dry deserts and regions with harsh winters. Unlike most traditional timber siding, which often depends on chemical preservatives to provide protection, Accoya wood siding benefits from an advanced modification process at the cellular level. Instead of coating the surface or only using thermal modification, the ‘acetylation’ process enhances the wood’s natural structure throughout, making it highly resistant to moisture, swelling, and shrinking.

This means that even in environments with significant temperature fluctuations or persistent humidity, Accoya wood siding remains remarkably stable.
