If you do miss this time frame it is quite easy to get it back so don't panic, Just get the sander out!

Thermowood Radiata Cladding:

Specification:

• Nominal Size: 25x150mm
• Finished Size: 19x140mm
• Face Cover: 130mm
• Lineal metres needed per square metre: 7.69LM
• Great Alternative to Canadian Western Red Cedar
• Recommended Wastage: 10-15%

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.

• Stable: Reduced warping, shrinking, or swelling, making it ideal for varied climates and conditions.

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

Applications

Thermowood Radiata cladding is a versatile and durable option suitable for:

• Residential and commercial exterior walls.

• Interior feature walls or ceilings.

• Saunas and more.

Specification:

• Size: 21x142mm
• Face Cover: Shadow Gap - 122mm, V-Groove - 132mm

Description

Thermowood Ayous is a premium, thermally modified timber prized for its sleek, knot-free appearance and exceptional consistency. The high-temperature kiln process alters the wood’s cellular structure, creating a product that is significantly more stable and resistant to the elements than standard untreated Ayous. It features a smooth, tactile surface and a rich, uniform brown colour that makes it an ideal choice for high-end architectural detailing.

Treatment

This timber is naturally durable and requires no chemical preservatives to maintain its integrity. While it can be left to weather (silver) naturally, we recommend applying a UV-protective oil (such as Osmo) every 2–5 years to maintain the original colour. If the timber begins to silver, the original tone can be easily restored by lightly sanding the surface before re-oiling.
