THERMO-MODIFICATION OF WOOD is a heat treatment process based on the use of high temperatures and steam.
No chemicals are used in the heat treatment process.
The process improves dimensional stability and biological resistance of wood.
Improves the thermal insulation properties of wood, since the process of thermal modification leads to a decrease in thermal conductivity.
Heat treatment removes the resin from the wood.
DRYING - The temperature rises to 130 degrees Celsius , since there is water in the chamber, and at a temperature of about 100 degrees, the water both in the chamber and in the wood begins to evaporate, due to which the wood is dried with steam, steam is a natural protection to prevent cracking of the wood. Steam also softens the wood, preparing it for chemical changes and modifications
THERMO-MODIFICATION - The temperature in the chamber rises to around 185-225 degrees Celsius . The maximum temperature depends on the desired end result, due to the way the wood will be used. When the peak temperature is reached, it is fixed for 2-3 hours (the time depends not only on the type of wood but also its quantity and geometric dimensions). The steam environment protects the wood from fire and also influences the chemical processes in the wood.
COOLING - The temperature in the chamber is reduced to 50-60 degrees Celsius, after which the wood is ready for mechanical processing.

- When using thermo wood under atmospheric influence, the natural moisture content during 5 years of operation is two times lower than that of regular wood.
- As with all materials exposed to natural weather conditions, mold growth can occur on the surface of thermo wood. Bacteria in the air or rain-borne dirt can cause fungus to grow on an untreated surface. However, this is only observed on the surface and can be removed - wiped off or scraped off.
- The most optimal protective coating systems for thermos wood includes an oily primer and a soluble-based alkyd top coating or a water-based acrylic coating.
