HJT-Holz: Our Story
HJT-Holz, a pioneering company in Vilppula, Finland, was born out of a passion for wood and innovation. With deep roots in the local timber industry, we embarked on a journey to transform ordinary wood into extraordinary products through thermal treatment. This process not only enhances the natural beauty of the wood, making it resemble fine hardwood, but also improves its durability and resistance. Today, HJT-Holz is at the forefront of sustainable wood processing, serving markets across Europe with high-quality, eco-friendly wood products.
Today, HJT-Holz continues to thrive as a leading innovator in the Finnish wood industry. The company has successfully doubled its production capacity by investing in automation and modernizing its facilities. Now under the leadership of new generation, HJT-Holz remains committed to delivering high-quality, thermally treated wood products that meet the growing demand for sustainable and aesthetically pleasing materials. With a strong focus on customer-centric solutions, HJT-Holz primarily exports to key European markets.

2022 - Our Most Efficient Year
During the coronavirus pandemic, HJT-Holz experienced a surge in demand for its thermally treated wood products as more people focused on home improvements. With lockdowns in place and a shift towards remote work, homeowners sought to enhance their living spaces, driving up the need for high-quality, sustainable materials. This boom in demand allowed HJT-Holz to leverage its recent investments in automation and production capacity.
The heightened interest in sustainable products during the pandemic aligned perfectly with HJT-Holz’s commitment to eco-friendly practices. Consumers increasingly preferred materials that not only looked good but were also environmentally responsible. HJT-Holz’s expertise in producing durable and aesthetically pleasing thermally treated wood met these evolving consumer preferences, making the company a preferred supplier for both domestic and international markets
To handle the increased demand, HJT-Holz capitalized on its expanded production facilities, ensuring timely delivery of its products to key European markets. The company’s ability to scale up quickly and maintain high standards of quality reinforced its reputation as a leader in the wood processing industry, positioning HJT-Holz for continued success even beyond the pandemic years.
