Yakisugi (焼杉), sometimes also known as shou sugi ban outside Japan, is a wood burning technique that has been used for centuries in Japan to extend the lifespan of wood in exterior applications. It was conceived before chemical treatments were available as a means of improving the longevity of wood by preventing decay, insect and mould infestation, while making planks more dimensionally stable and improving fire resistance. Typically used for siding and cladding on exteriors, the surface may be sealed and oiled for interior use, furniture and products.
