Lunawood enables innovative and long-lasting use of wood in all decorative surfaces. We modify the best certified Scandinavian timber into beautiful ThermoWood® products in our mills in the heart of Finland. Grown and strengthened nearly 80 years in the harsh climate of the Nordic region, the renewable forest provides us the best raw material that will last for decades. Lunawood products are thermally modified using only natural methods, heat and steam. Lunawood is most known for its dimensional stability, durability and sustainable nature. It doesn’t require surface treatments, which makes it an ecological choice throughout its life cycle. Wherever Lunawood ThermoWood® is used, it brings Nordic luxury and a natural feel to the space.

Product Properties

Benefits of Thermowood

Benefits of Thermowood

Lunawood ThermoWood® offers numerous advantages, making it a preferred choice for various applications where most wood materials won’t perform. The need for chemical preservatives is eliminated, as the treatment process itself sufficiently increases the wood’s durability and resistance to decay.
The wood’s dimensional stability is enhanced due to reduced moisture content, resulting in less warping, swelling, and shrinking. Lunawood ThermoWood® is appealing choice for exteriors and interiors with its golden brown color and natural appearance. As a completely chemical-free product, it is a safe choice for both homes and public spaces.



Lunawood ThermoWood® boasts an exceptional sustainability story that is genuinely true. Our products are sourced from the highest quality PEFC-certified raw materials and manufactured in Finland. We do not use any chemicals in our production. Sustainability is at the heart of everything we do, from wood sourcing to responsible production, ensuring our product has a long lifecycle and aligns with environmentally conscious practices.

Sensory Characteristics

We believe that material choices should be about much more than just looks and performance. In the case of Lunawood, the natural scent, the feel and the acoustic properties combined with the many health benefits of the wood, are an integral part of the appeal of our products. That’s why our products are ideal for any interior to increase comfort.

What is Thermowood?

ThermoWood® is a trademarked wood material that is manufactured completely without chemicals through a patented thermal modification process. This process involves treating the wood in high temperatures between 180°C to 230°C in a controlled environment. The high temperature alters the chemical and physical properties of the wood, improving its composition and performance. The  process increases the durability and stability of the wood, making it more resistant to decay. Thermowood is also less prone to warping, swelling, and shrinking compared to untreated wood, due to reduced moisture content. Additionally, Thermowood offers improved insulation properties as the thermal conductivity of the wood is reduced. In appearance, Thermowood is recognisable by its warm brown tone, which is even throughout the profile.

Why Thermowood?

  1. Durability: The thermal modification process significantly enhances the wood’s durability, making it more resistant to decay.
  2. Dimensional Stability: ThermoWood® undergoes less swelling and shrinkage compared to untreated wood, providing greater dimensional stability. This makes it ideal for uses where consistent size and shape are important, such as in cladding.
  3. Improved Weather Resistance: Thermowood is more resistant to weather compared to untreated wood, making it suitable for outdoor use also in challenging climates.
  4. Sustainable and Chemical free: ThermoWood® process doesn’t involve any chemicals, making it an environmentally friendly option. Lunawood’s raw materials are sourced from sustainably managed Nordic forests, further enhancing its eco-friendly properties.
  5. Improved Insulation Properties: Thermowood has better thermal insulation properties compared to untreated wood
  6. Low Maintenance: Due to its enhanced durability and resistance to rot, ThermoWood® requires only little maintenance over time, which can be a cost-saving advantage.
  7. No Resin: The thermal modification process removes resins from the wood, preventing resin leakage which can be a problem in certain applications with untreated wood.
