Naoshima is our version of Shou Sugi Ban and the primary product we are proud of at Zwarthout. The Douglas wood is deeply charred in our workshop in Leersum. Naoshima has an irregular structure and a characteristic pattern, that reflects beautifully in the sun. The brittle coal layer requires a specific detailing of the building to reduce the influence of wind and weather. We recommend that this type not be used above a height of 6 metres above ground level or exposed to wind on open ground. The carbon layer can stain, but does not wash out when it rains. The carbon layer ages over the years and then gets a beautiful patina (weathering), which fits the Japanese philosophy of Wabi Sabi.

Optionally, we can fixate the carbon layer with an ecological resin based on water, so that the carbon layer no longer stains and becomes somewhat tougher.
