What is Thermally Modified Wood?
Thermally modified wood is produced through a controlled heat treatment process that alters the wood’s chemical and physical properties. Typically, wood is heated to temperatures between 320°F and 446°F in an oxygen-free environment. This process enhances the wood’s durability, stability, and resistance to decay, making it suitable for various applications.
The treatment leads to a decrease in moisture absorption, reducing the wood’s tendency to warp or crack over time. It is an eco-friendly option, as it involves no harmful chemicals and can be made from sustainably sourced timber.
Benefits of Thermally Modified Wood Decking
1. Enhanced Durability
One of the most significant advantages of thermally modified wood is its increased durability. The thermal modification process not only makes the wood less susceptible to decay but also improves its ability to withstand harsh weather conditions. For instance, thermally modified ash and oak are known for their longevity, making them ideal candidates for outdoor decking solutions.
2. Superior Stability
Thermally modified wood exhibits reduced expansion and contraction rates, which is critical in outdoor applications. This stability means that your decking will maintain its shape and appearance over time, even with fluctuating temperatures and humidity levels. As reported by various manufacturers like www.americanarealwood.com and thermory.com, this stability leads to a significant decrease in maintenance requirements.
3. Aesthetic Appeal
Beyond its performance characteristics, thermally modified wood is visually striking. With a rich, dark finish, thermally modified ash adds elegance to any outdoor space. The natural grain patterns are enhanced through the thermal treatment, offering a unique look that appeals to design-conscious homeowners.
4. Eco-Friendly
The eco-friendliness of thermally modified wood stems from its sustainable sourcing and chemical-free treatment process. Unlike traditional wood treatments, which may involve harmful chemicals, thermally modified wood relies solely on heat and steam. This makes it a safer choice for both the environment and your living space.
5. Versatility in Applications
Thermally modified wood can be used in a variety of applications beyond decking. It is suitable for cladding, siding, and even indoor furniture. The versatility of this material allows architects and builders to create cohesive designs that utilize the same wood type for various elements of a home or commercial space.
Common Applications of Thermally Modified Wood Decking
1. Residential Decking
Thermally modified wood is a popular choice for residential decking due to its durability and aesthetic appeal. Homeowners looking for a long-lasting and beautiful outdoor space often opt for thermally modified ash or oak. These materials withstand the elements while providing a warm, inviting atmosphere.
2. Commercial Decking
Commercial properties also benefit from thermally modified wood. Public spaces such as parks, boardwalks, and outdoor dining areas require materials that can endure heavy foot traffic and varying weather. The stability and durability of thermally modified wood make it an ideal choice for these applications.
3. Siding and Cladding
In addition to decking, thermally modified wood is an excellent material for siding and cladding. The reduced moisture absorption and enhanced resistance to decay make it suitable for vertical applications, providing a beautiful and functional exterior finish.
4. Indoor Furniture
While thermally modified wood is primarily known for outdoor applications, it also finds its place in indoor furniture design. Its attractive appearance and improved stability make it a desirable option for tables, chairs, and cabinetry.
