The long-term durability of wood, especially in an outside area, requires a proper preservation treatment. Among the various modern wood modification techniques, (acetylation, furfurylation, silicification), thermal treatment at 180-250 °C in low-oxygen conditions, known as thermally modified timber (TMT), is likely the least environmentally problematic option. However, TMT is compromised by reduced structural integrity due […]
