ThermoWoodŽ is a registered trademark owned by International ThermoWood Association

The ThermoWoodŽ trademark is a sign of wood products manufactured via a method developed in Finland. Only the members of the International ThermoWood Association have legal right to use the word ThermoWood with thermally modified timber.

Thanks to their improved durability against decay, the products are well suited to applications involving demanding weather conditions. The beautiful, finewood-style look and dimensional stability make the products suitable for interior decoration. ThermoWood Concept ensures the technical and ecological quality of the genuine ThermoWood products.

The International ThermoWood Association was founded in 2000. The aim of the association is to generally promote the usage of ThermoWoodŽ products. Only members of the International ThermoWood Association are allowed to use the ThermoWoodŽ trademark. They co-operate in standardisation, quality control, and research, in order to enhance the use of the products.

Unfortunately the unlawful use of word ThermoWood occurs in marketing of thermally modified timber. Only the following companies have legal right to use the ThermoWood trademark in EU countries:

Arin Orman Ürünleri Ekosampo Oy Heinolan Ruskopuu Oy
HJT-Holz Oy Heatwood AB Koshii & Co. Ltd
Metsä Wood NasWood Novawood

It is very important for the users of thermally modified timber to know that the technical data published by the International ThermoWood Association is not valid for all thermally modified timber that is available in the market. The data is valid only for genuine ThermoWood products that are produced under the independent quality control system audited by accredited notified body.  Also product classification (classes Thermo-S and Thermo-D) is directly copied by some nonmember companies.

The registration of the ThermoWood trademark is strong. It is proven by the decision of the Office for Harmonization in The Internal Market (OHIM). In addition to EU, the ThermoWood trademark is registered also in Switzerland, Japan, China, the USA and Canada by the International ThermoWood Association (Lämpöpuuyhdistys ry).
