Thermo modified wood, also known as thermowood or thermally modified wood, is a natural and eco-friendly alternative to traditional timber. It undergoes a heat treatment process that enhances its durability, stability, and resistance to decay. This process does not involve the use of chemicals, making it an excellent choice for sustainable construction and design.
How is Thermo Modified Wood Made?
The production of thermowood involves heating the wood to temperatures between 160°C and 230°C in a controlled environment with minimal oxygen. This process changes the chemical structure of the wood, reducing moisture content and improving its properties.
Stages of Thermal Modification
- Drying: The wood is slowly heated to remove moisture.
- Heat Treatment: The wood is subjected to high temperatures, altering its internal structure.
- Cooling and Moisturizing: The wood is cooled down, and moisture is reintroduced to achieve the right balance.
Benefits of Thermally Modified Wood
- Enhanced Durability: Thermowood is highly resistant to decay, insects, and fungi.
- Dimensional Stability: It does not warp, shrink, or swell like untreated wood.
- Improved Thermal Insulation: It provides better heat resistance compared to regular wood.
- Eco-Friendly: No chemicals are used, making it safe for people and the environment.
- Attractive Appearance: The heat treatment enhances the wood’s natural color, giving it a rich and uniform tone.
Common Applications of Thermowood
Exterior Uses
Thanks to its durability, thermo modified wood is widely used for outdoor applications:
- Cladding and facades
- Decking and terraces
- Fencing and garden structures
Interior Uses
Its aesthetic appeal makes it popular for indoor applications as well:
- Flooring and wall panels
- Furniture and decorative elements
- Saunas and bathrooms
Comparison: Thermowood vs. Traditional Wood
Durability
While regular wood is prone to rotting and insect damage, thermally modified wood offers increased resistance, making it ideal for humid environments.
Maintenance
Unlike untreated wood, which requires frequent sealing and painting, thermowood has a long-lasting appearance with minimal upkeep.
Environmental Impact
Since thermo modified wood is processed without harmful chemicals, it is a sustainable and environmentally friendly choice.
Conclusion
Thermo modified wood is an innovative material that combines natural beauty with enhanced performance. Whether for exterior or interior applications, its durability, stability, and eco-friendliness make it a top choice for architects, designers, and homeowners alike.
