Accsys Technologies has added red alder to its Accoya range, expanding the species’ opportunities in exterior applications.

Red alder is often used for interior joinery, flooring and cabinetry but modification with Accsys’s acetylation technology could open up markets in exterior siding, decking and doors.

The species has been introduced after several years of material testing and prototype trials of applications including doors, windows, flooring, outdoor furniture and boat docks. Accoya Alder offers the same performance properties as original Accoya, including a European durability class 1 rating of EN 113:199 in use
classes 1-4.

American Hardwood Export Council European director David Venables said Accoya Alder was an exciting development for the timber trade.

“The improved durability provided by the wood modification process enhances exterior performance and gives specifiers a wider choice of natural sustainable and high-performing products. This is a validation of the opportunities for American hardwoods in the field of wood modification and we’re keen to see continued innovation and application of this technology on American hardwoods,” he said.

Accoya Alder will be available throughout Europe and North America.

• Accoya won the Best Technology category in the Sustain Magazine Awards last month.
