Thermo-treated ash wood becomes more resistant to fungus and rot without the use of chemicals. With this heat treatment, the color of the wood changes to nut brown, while the beautiful veins are preserved. The thermal treatment makes the wood suitable for outdoor use for garden furniture and other outdoor furniture.
