Thermally modified wood siding has become a popular choice for homeowners and builders due to its durability, sustainability, and aesthetic appeal. The process of thermal modification involves heating the wood to high temperatures in the absence of oxygen, which changes the wood's chemical and physical properties. This results in wood that is more resistant to decay, insects, and moisture, making it an ideal choice for exterior applications like siding.
One of the key benefits of thermally modified wood siding is its sustainability. By using domestically sourced and sustainably harvested timber, builders can reduce their environmental impact while still achieving a high-quality, performance-driven material. Additionally, the thermal modification process uses only heat and steam, without the need for chemicals or preservatives, making it a more eco-friendly choice.
Another advantage of thermally modified wood siding is its versatility in design and application. With a range of profiles and finishes available, builders can achieve a variety of looks, from modern and sleek to rustic and natural. Plus, the increased durability of the wood means it requires less maintenance over time, saving homeowners time and money in the long run.
What is Thermally Modified Wood?
Thermally modified wood (TMW) is a type of wood that has undergone a controlled pyrolysis process, which involves heating the wood to a temperature of over 180°C in an oxygen-free environment. This process changes the chemical structures of wood's cell wall components lignin, cellulose, and hemicellulose, which increases its durability. The thermal modification process also reduces the wood's equilibrium moisture content, making it more resistant to decay and insects.
Thermal Modification Process
The thermal modification process involves heating the wood to high temperatures in the absence of oxygen. This process changes the chemical structure of the wood, making it more durable and stable. During the process, the wood is heated until it reaches a temperature of over 180°C. The temperature is then maintained for a specific period of time, depending on the type of wood and the desired outcome. The wood is then cooled slowly to prevent any cracking or warping.
Benefits of Thermally Modified Wood
Thermally modified wood has several benefits over traditional wood. One of the primary benefits is its increased durability. The thermal modification process makes the wood more resistant to rot, decay, and insect infestation. This makes it an ideal choice for outdoor applications such as siding, decking, and fencing.
Another benefit of thermally modified wood is its improved stability. The process reduces the wood's equilibrium moisture content, which means that it is less likely to warp, twist, or crack over time. This makes it an ideal choice for applications where stability is important, such as flooring and paneling.
In addition to its durability and stability, thermally modified wood also has an attractive appearance. The process can enhance the natural color of the wood, giving it a rich, warm tone. This makes it an ideal choice for interior applications such as wall paneling and furniture.
Overall, thermally modified wood is a high-quality building material that offers several benefits over traditional wood. Its increased durability, stability, and attractive appearance make it an ideal choice for a wide range of applications.
Characteristics of Thermally Modified Wood Siding
Thermally modified wood siding is a popular choice among homeowners and builders due to its natural beauty and durability. The thermal modification process involves heating the wood to high temperatures, which changes its chemical composition and improves its physical properties. In this section, we will explore the characteristics of thermally modified wood siding.
Color and Aesthetic Appeal
One of the most notable characteristics of thermally modified wood siding is its unique color and aesthetic appeal. The thermal modification process changes the color of the wood, resulting in rich tones that are not found in untreated wood. The color of the wood can range from light brown to dark brown, depending on the species of wood and the temperature of the thermal modification process. The grain and unique characteristics of the wood remain, giving it a natural and authentic look.
Strength and Durability
Thermally modified wood siding is known for its strength and durability. The thermal modification process improves the strength and durability of the wood by removing moisture, which makes it less susceptible to decay and rot. The wood is also treated with a UV inhibitor, which helps to prevent the wood from fading or becoming discolored over time. This makes it an ideal choice for exterior applications, as it can withstand exposure to the elements.
Resistance to Environmental Factors
Thermally modified wood siding has excellent expansion and contraction properties, which make it resistant to environmental factors such as moisture and temperature changes. The wood is less likely to warp, twist, or crack, which helps to maintain its structural integrity over time. It is also resistant to insects and fungi, which can damage untreated wood.
In summary, thermally modified wood siding has unique color and aesthetic appeal, excellent strength and durability, and resistance to environmental factors. These characteristics make it a popular choice among homeowners and builders who are looking for a natural and durable siding option.
Installation and Maintenance
Installation Guidelines
Thermally modified wood siding is a great choice for those who are looking for a durable and long-lasting option for their home. Installation of thermally modified wood siding is similar to other wood siding products. It is important to follow the manufacturer's instructions for installation to ensure a proper and secure installation.
Before installation, it is recommended to acclimate the wood to the local environment. This means that the wood should be stored in the same environment where it will be installed for a few days to adjust to the temperature and humidity. This will help avoid any warping or twisting of the wood after installation.
It is also important to use the correct fasteners and spacing for the siding. The fasteners should be corrosion-resistant and compatible with the wood species. The spacing between the siding boards should be consistent to allow for expansion and contraction of the wood.
Maintenance and Care
Thermally modified wood siding requires minimal maintenance to keep it looking great for years to come. The siding should be cleaned periodically to remove any dirt or debris. A mild detergent and water can be used for cleaning. Avoid using a pressure washer as it can damage the wood.
Applying a finish to the siding can help protect it from the elements and extend its lifespan. There are several finishes available for thermally modified wood siding, including Cutek Extreme Penetrating Oil and UV Protective Surface Finish. These finishes can help protect the wood from UV rays, moisture, and insects.
It is important to follow the manufacturer's instructions for applying the finish. The finish should be applied to all sides of the siding before installation to ensure complete coverage. It is also recommended to reapply the finish every few years to maintain the protection.
In summary, installation of thermally modified wood siding is similar to other wood siding products, but it is important to follow the manufacturer's instructions for proper installation. Minimal maintenance is required for thermally modified wood siding, but periodic cleaning and application of a finish can help protect the wood from the elements.
