Accoya is a ‘new wood species’ whose performance credentials have been extensively researched and repeatedly demonstrated. It is a product that has properties, which match those of the best tropical hardwoods, yet, it is manufactured using a non-toxic acetylisation treatment and wood from sustainable sources.

With Class 1 durability, dimensional stability, resistance to mould and insects and ease in machining, the treatment provides a life expectancy externally of 50 to 60 years unprotected with surface coatings. Accoya represents a significant step forward in wood technology. This is the ideal material for exterior cladding, providing improved life expectancy of surface coatings for up to 10 years.
