How it works ?

Thermal modification is an advanced wood treatment process that goes beyond traditional kiln drying. It involves heating wood to temperatures up to 400°F (204°C) in specialized ovens. While kiln drying primarily removes “free water” from wood, thermal modification takes this a step further:

• It breaks down hydroxyl groups in the wood structure
• It reduces the wood’s moisture content to near zero
• The wood is then rehydrated to a stable moisture content using steam

This process is chemical-free, relying solely on heat and steam. The result is a material with significantly improved properties:

• Enhanced resistance to moisture-related issues
• Increased dimensional stability (less warping, bowing, or movement)
• Reduced appeal as a food source for insects

Thermal modification represents a leap forward in sustainable wood use. It allows for the utilization of fast-growing, previously less desirable species in exterior applications, often outperforming traditional exterior-rated woods.

Benefits of Thermally Modified Wood

• Enhanced Durability: Improved resistance to decay and insect damage
• Eco-Friendly: Utilizes responsibly sourced timber
• Aesthetic Appeal: Process enhances the wood’s natural beauty
• Versatility: Suitable for various applications from decking to furniture
• Reduced Maintenance: Requires less upkeep than untreated wood

Applications and Considerations

Thermally modified wood is an excellent choice for both exterior and interior applications. Its improved properties make it particularly suitable for:

• Outdoor decking and cladding
• Moisture-prone areas such as bathrooms or saunas
• Furniture and cabinetry
• Architectural accents and design features

When considering thermally modified wood for your project, consult with a knowledgeable professional to ensure it meets your specific requirements and local building codes.

Acetylation is a revolutionary process that enhances wood’s durability and stability. It works by replacing the wood’s natural hydroxyl groups, which attract water at the cellular level, with moisture-resistant acetyl groups.

The Natural State of Wood

Wood cellulose naturally contains a small number of acetyl groups. However, these are insufficient to provide significant benefits in terms of durability or stability.

The Acetylation Process

Through advanced scientific methods, it’s now possible to increase the number of acetyl groups in wood while reducing the hydroxyl groups. This results in an exceptionally durable and sustainable building material.

Benefits of Acetylated Wood

• Enhanced durability
• Improved stability
• Increased moisture resistance
• Extended lifespan

Impressive Longevity

The science behind this process allows for unprecedented warranties on acetylated wood products:

• 50 years for above-ground usage
• 25 years for in-ground or freshwater applications

These exceptional warranties are a testament to the effectiveness of the acetylation process in creating a superior wood product.
