At HJT-Holz, our ThermoWood® products start with carefully selected, high-quality raw materials. We focus on sourcing timber that meets the highest standards for sustainability, durability, and quality. Every piece of wood we process reflects our commitment to responsible forestry and exceptional craftsmanship. In this blog, we’ll explain where our raw materials come from and how they contribute to the superior quality of our ThermoWood® products.

1. Sourcing from Sustainable Partners

Great products begin with responsible sourcing. At HJT-Holz, we collaborate with trusted partners who commit to sustainable forestry practices. These partnerships ensure that we source our wood from well-managed forests, which prioritize forest health, biodiversity, and regeneration​. By working with suppliers who share our values, we guarantee top-quality raw materials that are environmentally responsible.

2. Finest Finnish Pine and Spruce

We source our softwood materials, such as pine (Pinus sylvestris) and spruce (Picea abies), from Finland. Finnish forests provide us with high-quality timber due to the region’s cold climate, which promotes slow tree growth. This results in dense, strong wood that is perfect for our thermal modification process​. We select top logs with straight grains and minimal imperfections to create ThermoPine and ThermoSpruce, which excel in both durability and dimensional stability. By choosing the best pine and spruce, we ensure that our products meet the high demands of both outdoor and indoor applications.

3. Responsibly Sourced Hardwoods

In addition to softwoods, we source hardwoods like ThermoAsh from sustainably managed forests in Europe. Ash (Fraxinus excelsior) is known for its durability and beautiful grain, making it ideal for high-end projects like decking and cladding​.

We also source African hardwoods like Ayous (Triplochiton scleroxylon) and Fraké (Terminalia superba) through responsible suppliers. These woods naturally resist decay and insects, making them perfect for exterior applications. By sourcing these hardwoods responsibly, we ensure long-lasting beauty and performance while protecting the environment.

4. Certified Forestry Practices

At HJT-Holz, we source all our wood from suppliers who comply with recognized certification standards like FSC® and PEFC. These certifications guarantee that we harvest the wood in a way that protects the environment and respects local communities​. By following these certifications, we reflect our dedication to sustainability and provide our customers with responsibly sourced, high-quality wood for their projects.

5. Rigorous Quality Control

Our team thoroughly inspects each batch of raw materials upon arrival. We enforce strict quality control measures to ensure that only the best wood moves forward to the thermal modification process. By focusing on this attention to detail, we guarantee that our ThermoWood® products remain free from defects and perform well under harsh conditions​.

6. Environmentally Friendly Production

The ThermoWood® production process further enhances the quality of our raw materials. We modify the wood using heat and steam, which improves its natural properties without the need for harmful chemicals. This eco-friendly process boosts the wood’s durability, stability, and resistance to decay, making it ideal for outdoor and indoor use​.

7. A Commitment to Sustainability

Sustainability guides every decision we make at HJT-Holz. We focus on sourcing eco-friendly raw materials and producing wood that minimizes environmental impact. By partnering with certified suppliers, we contribute to forest conservation and support responsible forestry practices​.

8. Conclusion: Quality Starts with the Right Materials

At HJT-Holz, we believe that high-quality products start with high-quality raw materials. By carefully selecting the best timber from Finnish softwoods and European and African hardwoods, we ensure that our ThermoWood® products deliver exceptional performance. Our commitment to sustainability, combined with strict quality control and certified sourcing, guarantees that every piece of wood we produce meets modern construction demands while protecting the environment.
