Available Through Hardwoods
Modified Wood for Exterior Cladding, Decking & Millwork
Hardwoods supplies Accoya for commercial project teams, fabricators, millwork shops, and trade professionals who need a premium exterior wood solution with reliable performance and dependable distribution support.
Real Wood Performance for Demanding Exterior Applications
Accoya® modified wood is engineered for long-term exterior performance, offering the warmth and workability of real wood with enhanced resistance to movement, moisture, rot, and outdoor exposure.
Two Product Pathways
Accoya Natural and Accoya Color Grey
Hardwoods supplies Accoya products for trade and commercial customers seeking premium exterior wood performance — a natural pathway that gradually silvers with outdoor exposure, and a pre-greyed pathway that delivers a weathered visual from day one. Product availability may vary by branch and market.
