Shou Sugi Ban This is a traditional Japanese method of preserving cedar, where it is burned enough to create a layer of char on the outside. The char serves a number of functions: it seals and preserves the wood, it makes it significantly more fire-resistant, and termites and bugs hate it. According to Charred Wood, a supplier of Shou sugi ban, it can last 80 to 100 years without maintenance, and much longer if it is refinished with oil every 10 to 15 years.
