Appearance and Texture

Thermowood Radiata Pine undergoes a thermal modification process that enhances its colour and texture. Compared to untreated Radiata, the thermal treatment gives the wood a deeper and more uniform brown tone, often with subtle variations. The treatment accentuates the natural grain of the pine, providing an elegant and textured appearance. This creates a refined and visually appealing cladding option suitable for various design aesthetics.

The thermal treatment also improves the texture, giving the wood a smooth and polished feel, making it an excellent choice for both indoor and outdoor applications as well as saunas. 

Treatment Recommendations

While Thermowood Radiata is naturally durable due to the thermal modification process, applying a protective finish is recommended to maintain its rich appearance. Products such as Osmo UV Oil or Treatex UV Oil can enhance the wood’s natural beauty and help prevent it from weathering to a silvery-gray tone over time.

• Maintenance Schedule: Apply a fresh coat of oil every 2–5 years to preserve the original color.

• If the wood has weathered or the maintenance interval has been missed, the original appearance can be restored with light sanding and reapplication of the oil.

Key Facts

• Durable: Enhanced resistance to decay and weathering due to the thermal modification process.

• Sustainable: Thermowood Radiata is often sourced from responsibly managed forests, offering an eco-friendly cladding choice.
