LONDON, ENGLAND – North American species red alder is now among Accsys Technologies modified-wood products offerings. Accoya Alder undergoes a proprietary modification process called "acetylation" that improves its durability, hardness, water absorption, and dimensional Modified American Red Alder Offered by Accsysstability while retaining its natural strength and beauty.

Alder boasts a fine grain and a medium tone—a clean, attractive look popular for construction of interior doors, cabinetry, flooring, and moldings. By applying the patented acetylation technology, alder is suitable for exterior applications, including screens, outdoor furniture, windows, and exterior doors, while maintaining the species’ aesthetic qualities.

Acetylation wood technology alters the wood’s reaction with water by permanently replacing the molecules that want to bond with water with more stable acetyl groups. Acetyl groups are naturally present in all wood species, which means that nothing toxic is added. The altered cell structure of the wood makes it an unrecognizable wood source for insects and prevents fungal decay, says Accsys Technologies.
