Fundamentals of Thermally Modified Wood

Thermally modified wood is a type of heat-treated wood that undergoes a controlled pyrolysis process that changes the chemical structure of the wood's cell wall components. This process leads to a more stable, durable, and rot-resistant wood product that is ideal for a range of indoor and outdoor applications. In this section, you will learn about the fundamental aspects of thermally modified wood, including its properties, the thermal modification process, and the species suitability.

Understanding Thermal Modification

Thermal modification is a process that involves exposing wood to a high temperature in the absence of oxygen. This process leads to the breakdown of hemicellulose, which is the component of wood that is responsible for its susceptibility to decay and moisture damage. The thermal modification process also causes changes to the lignin and cellulose components of wood, which results in a more stable and durable wood product.

The temperature and time of the thermal modification process are critical factors that affect the properties of the final product. The temperature range for thermal modification is typically between 180-240°C, and the time of exposure can range from a few hours to several days. The moisture content of the wood also plays a critical role in the thermal modification process, as it affects the rate of chemical reactions that occur during the process.

Varieties and Species Suitability

Thermally modified wood is available in a range of species, including hardwoods and softwoods. Ash, pine, spruce, poplar, and birch are among the most commonly used species for thermal modification. However, not all wood species are suitable for thermal modification, as some species may not respond well to the process. The species suitability for thermal modification depends on several factors, including the density, cell structure, and chemical composition of the wood.

At Westwood Millworks, we pride ourselves on providing high-quality thermally treated wood products that are ideal for a range of applications. Our thermally modified wood products are made using the latest technology and the highest quality wood species, ensuring that you get a product that is durable, stable, and resistant to decay and moisture damage.

Properties and Performance

Durability and Decay Resistance

Thermally modified wood is known for its excellent durability and decay resistance. The thermal modification process removes hemicellulose, which is the primary food source for decay fungi. This results in wood that is less susceptible to decay and insect damage. Additionally, the thermal modification process increases the wood's resistance to moisture, which further improves its durability.

At Westwood Millworks, we take pride in our thermally treated wood products. Our products are carefully treated to ensure maximum durability and decay resistance. We use only the highest quality wood and employ strict quality control measures to ensure that our products meet the highest standards.

Dimensional Stability and Moisture Dynamics

Thermally modified wood is also known for its excellent dimensional stability and moisture dynamics. The thermal modification process removes moisture from the wood, which reduces its tendency to shrink, warp, or twist. This makes it an ideal material for outdoor applications, where exposure to moisture and temperature changes can cause other types of wood to deteriorate quickly.

At Westwood Millworks, we understand the importance of dimensional stability and moisture dynamics. That's why we carefully monitor the moisture content of our products and use only the highest quality wood to ensure maximum stability and resistance to moisture.

Strength and Structural Integrity

Thermally modified wood is also known for its excellent strength and structural integrity. The thermal modification process increases the wood's strength by removing hemicellulose and lignin, which are the weaker components of the wood. This results in wood that is stronger, more durable, and less brittle.

Gluing Considerations for Thermally Modified Wood

When it comes to gluing thermally modified wood, there are several considerations to keep in mind to ensure a successful bond. In this section, we'll cover adhesive selection, surface preparation, glue application, and curing.

Adhesive Selection

Choosing the right adhesive is crucial for a strong bond with thermally modified wood. PVAC glue is a popular choice for gluing thermally modified wood due to its ability to penetrate the wood fibers and create a strong bond. Water-based glues are also a good option as they are easy to clean up and have a longer open time than PVAC adhesives.

Surface Preparation

Before gluing thermally modified wood, it's important to properly prepare the surface. The wood should be clean and dry, with no visible signs of resin or other contaminants. Sanding the surface can help improve the glue line by creating a rough surface for the adhesive to grip onto.

Glue Application and Curing

When applying glue to thermally modified wood, it's important to apply enough pressure to ensure good glue line contact. This can be achieved through the use of clamps or other pressure-applying devices. The glue should be applied evenly and allowed to dry under dry conditions for optimal curing.

At Westwood Millworks, we offer high-quality thermally-treated wood products that are perfect for a wide range of applications.
