THERMOWOOD

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. Low oxygen content prevents the wood from burning at these high temperatures. Several different technologies are introduced using different media including nitrogen gas, steam and hot oil.

IZALCO provides thermowood with high durability in different classes (1-3), which might be seen as environmentally friendly.  The biological resistance against some micro-organisms and insects is considered in our products. Shrinking and swelling is reduced up to 50-90%. The treated wood is ranges from light honey to dark brown in color and can be used inside or outdoors, in any climate. Izalco provides standard treatment classes of thermowoods named Thermo-S (190°C +/-3°C ) and Thermo-D (212°C +/-3°C ) for softwoods, and hardwoods Thermo-S (185°C +/-3°C ) and Thermo-D (200°C +/-3°C).
