Shou Sugi Ban 焼杉板 (or Yakisugi) is an ancient Japanese exterior siding technique that preserves wood by charring it with fire. Traditionally, Sugi wood (Japanese cedar) was used. The process involves charring the wood, cooling it, cleaning it, and finishing it with a natural oil.
Shou Sugi Ban is an environmentally friendly way to preserve timber and (interesetingly) make it fire-resistant. Chemical preservatives, paints, and retardants are unnecessary. In addition to exterior uses, this Japanese technique is now found in interior rooms, furniture, and artwork.More pictures and video on next page:
