Basics of Thermal Modification

Thermal modification is a process that involves heating wood to high temperatures in a controlled environment, which changes its physical and chemical properties. The process involves the use of heat, steam, and pressure to modify the wood's structure, making it more resistant to decay, insects, and weathering. The result is a durable, long-lasting wood product that is ideal for outdoor use.

The Science Behind Thermal Modification

The thermal modification process involves heating the wood to temperatures between 160°C and 240°C in a kiln, where it is exposed to steam and pressure. The heat and steam cause the wood's cell walls to break down, which changes its structure and chemical composition. The result is a wood product that is more stable, less prone to warping and cracking, and more resistant to moisture and decay.

Comparing Thermowood® and Novawood Technology

There are two main types of thermal modification technology: Thermowood® and Novawood. Thermowood® is a trademarked process that was developed in Finland, while Novawood is a patented process that was developed in Turkey. Both processes involve heating the wood to high temperatures, but there are some differences in the way the two technologies work.

Thermowood® involves heating the wood to temperatures between 190°C and 212°C, while Novawood uses temperatures between 180°C and 220°C. Both technologies use steam and pressure to modify the wood's structure, but Novawood also uses a vacuum to remove moisture from the wood. The result is a wood product that is more stable, durable, and resistant to decay and insects.

At Westwood Millworks, we use both Thermowood® and Novawood technology to produce high-quality thermally-treated wood products. Our products are made from sustainably sourced wood species and are available in a range of sizes and finishes to suit your needs. With our commitment to quality and sustainability, we are the best option for thermally-treated wood products.

Characteristics of Thermally Modified Wood

Thermally modified wood is a type of wood that has been treated with heat to improve its physical and mechanical properties. This process involves heating the wood to temperatures between 160 and 240°C in the absence of oxygen, which changes the chemical and physical structure of the wood. Here are some of the characteristics of thermally modified wood:

Physical and Mechanical Properties

Thermally modified wood has several physical and mechanical properties that make it an attractive option for various applications. The process of thermal modification improves the durability of softwood species, allowing them to achieve durability class 1-3, according to European Standard EN 350-2, which is typically reserved for hardwood species. Additionally, the process increases the stability of the wood, making it less susceptible to shrinking, swelling, warping, and other forms of dimensional instability. This makes thermally modified wood an excellent choice for outdoor applications, such as decking, cladding, and fencing.

Moisture Content and Dimensional Stability

One of the key benefits of thermally modified wood is its improved moisture content and dimensional stability. The process of thermal modification reduces the wood's equilibrium moisture content, which makes it more resistant to moisture-related problems, such as decay, rot, and insect infestation. Additionally, the process increases the dimensional stability of the wood, reducing its tendency to expand and contract with changes in relative humidity. This means that thermally modified wood is less likely to warp, twist, or crack over time, which makes it an ideal choice for applications where dimensional stability is critical.

At Westwood Millworks, we specialize in producing high-quality thermally modified wood products that meet the highest standards of durability, stability, and performance. Our products are made from carefully selected softwood species that have been treated with heat to achieve the highest levels of durability and stability. Whether you're looking for decking, cladding, or fencing, our thermally modified wood products are the best option for your project.

Wood Species and Modification Effects

Hardwoods and Softwoods

Thermal modification of wood affects different wood species in various ways. Hardwoods, such as ash, oak, teak, and ipe, have a higher density and tend to undergo more significant changes during the thermal modification process. Softwoods, such as pine, spruce, and poplar, have a lower density and tend to undergo less significant changes during the thermal modification process.

Impact on Cell Structure and Chemistry

The thermal modification process affects the chemical composition and cell structure of wood. The process causes the hemicelluloses and sugars in wood to degrade, while the lignin becomes more stable. This results in a more stable, durable, and moisture-resistant wood product.

According to research, thermally modified wood has been classified as durability class 1, which is the highest class of durability. The use of thermally modified wood in outdoor applications is therefore highly recommended.

At Westwood Millworks, we pride ourselves on producing the best thermally-treated wood products. Our products are made from carefully selected hardwoods and softwoods, and our thermal modification process ensures that our products are of the highest quality.
