Tidewater Lumber is proud to carry Accoya, an ultra-high performance sustainable wood for architects, manufacturers and homeowners alike.
Accoya® is a high-performance, sustainably sourced wood engineered through a patented acetylation process that transforms fast‑growing softwoods like Radiata pine into a Class 1 durable material. This transformative method modifies the wood’s cellular structure to drastically reduce moisture absorption—by about 80%—resulting in exceptional dimensional stability and resistance to decay and insects. Accoya® is backed by an industry-leading warranty—50 years above ground and 25 years submerged—and holds multiple sustainability certifications, including FSC® and Cradle to Cradle® Gold.
Accoya® wood offers exceptional dimensional stability, making it one of the most reliable choices for demanding exterior and interior applications. Its patented acetylation process reduces the wood’s ability to absorb moisture by up to 80%, meaning it won’t noticeably swell, shrink, or warp — even in harsh climates or fluctuating weather. This stability ensures tight joints, smooth surfaces, and a consistently polished appearance over time, reducing maintenance and increasing product lifespan. Whether you’re installing siding, decking, windows, or doors, Accoya stays true to its form, delivering long-term performance and peace of mind.
Accoya is ideal for wood siding, offering long-term stability, resistance to rot, and a clean, refined look. It holds up in every climate without warping or cupping. Whether you’re going for modern or traditional, Accoya siding stays straight, looks great, and lasts for decades with minimal maintenance.
Accoya decking combines natural wood beauty with outstanding durability. It resists rot, swelling, and surface damage, making it perfect for outdoor living spaces. Cool to the touch and easy to maintain, it performs in all weather and outlasts many hardwoods and composites.
Accoya is a top choice for windows and doors that need tight tolerances and long-term reliability. It resists warping and shrinkage, even with changes in temperature and humidity. Paint holds beautifully, and its strength ensures smooth operation and a crisp, finished look that lasts year after year.
