5/4 x 6" x RL FSC Accoya Radiata Pine Natural A1 RGH FSC Accoya

5/4 x 6" x RL FSC Accoya Radiata Pine Natural A1 Rough Sawn is a premium acetylated wood board engineered for exterior durability, dimensional stability, and long-term performance. Manufactured from FSC® certified Radiata Pine, Accoya® is modified through an advanced acetylation process that improves resistance to moisture, rot, decay, swelling, shrinkage, and insect attack while maintaining the natural appearance and workability of wood.

This 5/4 x 6" random length Accoya board is supplied in Natural A1 rough sawn grade, making it a strong option for exterior trim, cladding, siding, soffits, façades, windows, doors, architectural millwork, and other commercial exterior applications where stability and service life are important. The added 5/4 thickness provides additional material depth for profiles, machining, and applications requiring a more substantial board dimension.

Because Accoya is modified through the full cross-section of the board, it delivers consistent performance after cutting, machining, profiling, or finishing. Accoya combines the beauty of natural wood with enhanced coating performance, reduced maintenance expectations, and dependable exterior performance for architectural and specification-driven projects.
