Thermowood - Thermally Modified Timber (TMT) is the process of minimizing dehumidification and deformation behavior by increasing the internal temperature of the wood above 200℃. As a result of the decomposition of relative humidity in the wood, the products become permanently resistant to fungi and decay. They also reach maximum durability against climatic forces.

Thermally modified wood does not produce harmful organisms like fungi and it does not bend or contract. Also, it is not adversely affected by seasonal conditions. By decomposing the relative humidity in the wood, thermowood products become more durable to humidity, more resistant to decay and external weather conditions.

Tantimber applies the advanced processing steps in the thermal modification process and production phase, which are defined as high-quality standards. Tantimber products are produced according to European technical norms (CEN/TS 15679), and they take part in the first and second class in terms of durability classes (EN 350-2, EN 355).

Tantimber’s thermowood process is a natural process in which no chemical substance is used at any stage. The products are completely eco-friendly and recyclable. They do not contain any harmful substance.

Tantimber is a member of International Thermowood Association (ITWA).


Thermowood - Thermally Modified Wood (TMT) offers many advantages comparing to other wood species that became products by conventional drying methods.

Due to thermowood process, with the help of high heat, we remove the water inside the wood, balance the moisture exchange, minimize the operation of products and increase the biological life cycle to 25 years and above. During all these processes no chemical is used, and the wood is decontaminated from all inherent negative characteristics.

Tantimber Thermowood products can be safely used in all weather conditions and difficult area of use.

Tantimber is a member of International Thermowood Association. We produce according to European technical norms (CEN/TS 15679) and EN 350-2. Depending on the tree species, the wood that we work on with thermal modification takes part in the first and second class in terms of durability.
