🌳 Thermal modification of wood

Heat treatment of wood is a modern technology for producing natural building boards by modifying its structure under the influence of high temperatures.

The idea of this type of processing is quite simple: the wood is gradually steamed, dried, thermally modified and stabilized. And although the wood hardening scheme seems simple, proper preparation of wood is only possible in industrial conditions in compliance with technological requirements and rules. Only such wood is guaranteed to meet certification requirements and will last a long time.

🌳 Technology of heat treatment of wood in production
All stages of wood thermal treatment involve working with high temperatures and require maintaining the technology to avoid fire and damage to the wood. This can be ensured and controlled only in the conditions of industrial thermal dryers.

✅ Steam wood treatment

Production involves treating natural wood with steam at temperatures of 170-250 degrees, which changes a number of chemical and physical properties of the material. The peculiarity of this stage is the destruction of hemicellulose under the influence of temperatures. The main factors influencing the material are water vapor and high temperature. No chemicals or reagents are used! It is this circumstance that determines the environmental friendliness of thermowood.

✅ Drying wood. Thermal drying

• At the next stage, the board is dried and gets rid of excess moisture from the wood. At the same time, a regime of high temperatures exceeding the fire threshold of wood is maintained. Avoid sunburn by creating an oxygen-free environment in the heat chamber. The process of technological replacement of air with carbon dioxide, water vapor or oil is involved.
• Thermal drying of wood is the longest stage. At this stage, under the influence of high temperatures, moisture from the wood evaporates almost completely. For thermal boards, a humidity level of 4-8% is considered acceptable (depending on the type of wood and the thickness of the board).
• Thermal modification of wood lasts 2-4 hours and involves processing the material at high temperatures. To avoid fire, a protective steam environment is created in the chamber, which provokes chemical changes in the wood.

✅ Wood stabilization

The final stage, stabilization of the wood board, involves gradual controlled cooling of the material.

Industrial heat treatment of wood lasts up to 3 days. The production of reliable, high-quality thermally modified boards is possible only in industrial conditions.

Craftsmen are trying to reproduce a simplified heat treatment scheme at home, using homemade heat drying. However, thermal modification at the molecular level is not possible at home. This approach is extremely unsafe and risks fire and damage to materials. On thematic forums about do-it-yourself thermal drying, there are many reviews about disastrous experiences and unsuccessful attempts that led to losses and loss of wood.

It’s safer to contact the manufacturer and quickly purchase high-quality and reliable thermal wood that has a certificate and quality guarantees, or order the service of heat treatment of customer-supplied wood of different species in large quantities.

🌳 Characteristics of thermally modified wood:

• environmental friendliness;
• strength;
• reliability in operation;
• does not deform;
• comparatively less weight;
• moisture resistance;
• fire resistance;
• not subject to deformation under the influence of external factors (precipitation, frost, sun rays);
• does not rot, is resistant to mold and fungi;
• eliminates damage from insects, parasites and rodents.

🌳 Thermal wood processing

Natural wood, even high-end wood, requires care.

Several types of thermowood surface coating agents are used.

🌳 Thermal wood coating products:

• oil;
• wax;
• varnish;
• dye.

🌳 Main characteristics of each approach:

• Waxing thermowood protects the board from moisture, but the surface stops breathing.
• Oil impregnation is the best method of protecting wood, as it has antiseptic properties and does not interfere with moisture exchange. Oils based on natural wax are also widely used. This type of coating combines the advantages of two types of products.
• Painting protects well from sunlight and rain, but different types of paint have different periods of guaranteed protection.
