Sakaide

by Zwarthout | Shou Sugi Ban · Netherlands · WOO544 · Published 17 Feb 2026
About this material

Sakaide has a beautiful, contrasting flame pattern, giving the wood a rustic, warm appearance. The planks are sawn flat (with the annual rings), and then charred one by one in the furnace. The planks are then carefully brushed and treated.

Sakaide is made from the Douglas fir. A type of wood originating from FSC® certified forests in the Netherlands. The knots give the wood an extra uneven effect. During the charring process, knots up to 2 cm in size can fall out. It has durability class 3, which makes it ideal for sustainable cladding.

Sakaide has fire classification Class D (EN 13501-1).
