Thermo Oak is a modified hardwood derived from European Oak (Quercus robur, Quercus petraea) or American White Oak (Quercus alba). The wood undergoes a specialized thermal modification process, where it is heated to high temperatures (typically between 180°C and 220°C) in a low-oxygen environment. This process enhances the wood’s durability, stability, and color, making it an excellent choice for both interior and exterior applications.

Quality and Characteristics
Appearance
- Thermo Oak has a rich, dark brown color, often resembling tropical hardwoods.
- The process enhances the natural grain, making it more pronounced and visually striking.
- It has a silky-smooth texture, adding to its premium aesthetic.
Durability and Strength
- The thermal treatment increases the wood’s resistance to moisture, decay, and fungal attacks, making it ideal for outdoor use.
- Thermo Oak has improved dimensional stability, meaning it is less likely to shrink, warp, or expand due to humidity changes.
- While the process makes the wood more durable, it also slightly reduces its natural hardness, making it more brittle than untreated Oak.
Workability
- Thermo Oak is easy to machine, cut, and shape, though its increased brittleness requires careful handling.
- It does not require chemical treatments since the thermal process naturally enhances its properties.
- It is best finished with natural oils or waxes to maintain its rich color and protect the surface.
Common Uses
- Exterior cladding and decking due to its enhanced weather resistance
- High-end flooring and wall paneling for luxury interiors
- Furniture and cabinetry for a sophisticated, dark wood aesthetic
- Saunas and bathrooms where moisture resistance is crucial
- Architectural millwork and design elements
