Shou Sugi Ban ACCOYA Deep Char by Pioneer Millworks. Black wood siding and paneling that is burned and coated with non-toxic, water-based polyurethane

Accoya Deep Char

Traditionally Inspired, American Made™—an 18th century technique for preserving wood with fire is updated to meet 21st century design and performance standards. With our Forest Stewardship Council® Certified and Cradle-to-Cradle Certified™ ACCOYA Deep Char we aggressively burn each board until the signature “alligator skin” texture is achieved, then apply an unobtrusive finish to enhance and protect the iridescent black surface.

Pioneer Millworks is an approved Accoya manufacturer.

ACCOYA Deep Char combines durability and sustainability. This modern, acetylated wood option provides stability in nearly any environment. Traditionally maintenance-free, the charred layer is expected to change over time when exposed to the elements. We finish our Deep Char with an ebony tinted poly sealer to protect and prolong its distinctive look—ACCOYA Deep Char provides longevity to be enjoyed for decades to come.
