Shou-sugi-ban 焼杉板, or burnt sugi board is a Japanese technique of creating timber cladding that should last over 80 years. Sugi is known as Japanese cedar, Instead of sugi, our wood species are Belinga. Old traditional Japanese houses use shou-sugi-ban for their external timber cladding, although rarely used now (replaced by manmade plastic or composite). The sugi was burnt to resist rot and fire. Supposedly it’s difficult for something already burnt to a charcoal finish to catch fire again.
