About our Family business
We are manufacturing ThermoWood®
Our family business specializes in the production and further processing of heat-treated wood. With over two decades of experience since our establishment in 1997, we’ve been dedicated members of the Finnish Thermowood Association since 2000, allowing us to proudly bear the association’s ThermoWood® trademark. This affiliation means active collaboration in areas such as quality control and research.
HJT-Holz in a nutshell
Our operational footprint includes seven advanced heat treatment facilities strategically located in Vilppula and Kolho, Finland. These facilities, coupled with our new production lines, grant us a robust total capacity of approximately 40,000 m3
Remarkably, 95% of our meticulously crafted products find their way to international markets through our commitment to export excellence.
