Thermally modified wood is wood that has been modified by a controlled pyrolysis process of wood being heated (> 180 °C) in absence of oxygen inducing some chemical changes to the chemical structures of cell wall components (lignin, cellulose and hemicellulose) in the wood in order to increase its durability.
Industrial thermal modification processes typically aim at improving the biological durability of less durable wood species and enhancing the dimensional stability of the wood or wood-based products.
