What’s the difference between natural and carbonised bamboo?Natural dark brown bamboo screening has been made from naturally growing dark bamboo canes. Carbonised bamboo screening has a dark caramel colour which has been achieved by smoking golden-coloured bamboo in an industrial kiln, this gives each cane a deep, rich colour. Similar to the process of Shou Sugi Ban, this carbonised product is a great contemporary solution to chemically treated materials. The treatment involves burning the outer layer of the bamboo with a high concentration of heat, removing the charred material, then sealing the bamboo for a brilliant finish.
