Thermowood is a type of industrial wood that, as a result of a process called thermal modification, its cell wall components are destroyed, and by reorganizing, its moisture content is very high (something around 4 to 6 percent). ) decreases, which also causes a decrease in the shrinkage of wood, an increase in the strength and durability of wood, a significant increase in resistance to water and humidity, and many other benefits. The thermo process is done without any chemicals and during it no damage is done to the wood. This product was initially developed in Finland (especially by VVT Technical Research Center of Finland) and now this country is the leader of this industry and the best thermo wood is produced in Finland.
Thermo wood in terms of wood species. which is made with it is divided into two categories: soft wood and hardwood, the type of hardwood in our country is mostly from the wood of the sparrow tongue (Ven) or Ash, and the type of soft wood is often They are made from pine wood and are available. Thermal pine wood is used in the facade of the building or in vertical places, and thermo wood of sparrow tongue is often used in floors and areas that need more resistance and durability.
Tips to recognize the quality of thermo wood
Thermo wood has a specific and uniform color that depends on the time and amount of heat that depends on the wood.
The core of the thermo wood should not be light in color, this indicates the non-standardity of the thermo process.
Woods from Finland, Northern Europe and Scandinavia, which are the best thermo wood, have butterfly knots, otherwise it may be Russian wood and or they are non-pine, which you should pay close attention to when buying. The beginning or the end of the wood of thermo wood can be seen, the more the knots are further apart and open, it means that the wood has moved away from the heart of the tree.
No cracking on the surface and section of thermo wood Grade A is not acceptable.
The surface of thermo wood must be completely smooth and polished without any burrs or wood shavings.
Advantages of Thermowood
With the progress of the current society, one of the ways to create a favorable environment for the body and soul in life is to use natural elements and familiar objects for the mind. Also, with the progress of the construction industry in the world and the expansion of new constructions, the use of Thermowood ) has also become more widespread. Thermowood is usually known as thermowood in Iran. These two expressions are equivalent and have no difference. Thermo wood is one of the most widely used elements in the construction industry. Wood has the desire to grow, grow, soften in human life, and with its proper use in the living environment, a calm and pleasant atmosphere can be created. Thermowood gives us the sense of beauty, peace and naturalness that comes from wood and cannot be compared with any other material.
In general, the advantages of Thermowood can be summarized as follows:
Light and light weight compared to similar and equivalent materials
Maintaining the humidity of the environment at the standard level of human natural needs
Normalizing sudden changes in temperature (cold to heat and heat to cold)< br> Faster installation and cleaner
much more ability against fire, water, storm and cold compared to other woods
being degradable and not harming the environment during destruction (ecological design) to external pressures (such as an earthquake)
unique sound insulation (due to keeping air in its pores)
with high durability against rotting in all kinds of weather conditions
resistant to warping and changing dimensions< br> Resistant to Attack of insects, micro-organisms, and all kinds of fungi and mold
Types of thermowood in terms of production
Thermo S
This type has stable resistance against environmental conditions. Thermo S is heated at 180°C to increase its resistance. As a result, the products that are made of thermo S may have a 6 to 8 percent change in dimensions and become swollen.
Thermo D
Type D has high durability. Thermo D heats up to 220 degrees Celsius and this makes it highly resistant to environmental conditions. The amount of humidity and temperature conditions of this type of thermowood is between 5 and 6 percent change and swelling.
Types of termwood in terms of species
Thermwood with soft wood
Thermwood with soft wood is made from coniferous trees such as cypress, poplar and pine. This type is more fragile and weak than thermod with hard wood. It also has a lower density than the hard type. Termwood with soft wood is used in building facades due to its lightness and affordability.
Termwood with hard wood
Termwood with hardwood from wide trees. Leaves are produced and it is one of the most popular types of wood, which is produced and made from the wood of walnut, fir, oak, maple, cherry, beech and sparrow trees.
Factors affecting the price of thermowood
The price of thermowood wood is calculated based on the square meter and its thickness has a great impact on the price of this product. The square meter unit is an accurate and easy measure for calculating thermowood used in thermowood flooring or thermowood facade, and building architects can estimate the amount of wood consumption and its price according to the plan.
It should be noted that the use of advanced equipment and machinery may also affect the price of thermowood.
