Thermally Modified vs Pressure Treated Wood: A Comparison by Westwood Millworks

Thermally Modified vs Pressure Treated Wood: A Comparison by Westwood Millworks

If you're in the market for wood products, you may be wondering which type of wood is best for your project: thermally modified or pressure treated. Both types of wood have unique characteristics that make them appealing for different reasons. Thermally modified wood is known for its durability and resistance to decay, while pressure treated wood is often used for its affordability and strength.

At Westwood Millworks, we specialize in thermally-treated wood products, and we believe that this type of wood is the best option for a variety of projects. Unlike pressure treated wood, which is treated with chemicals to prevent decay and insect damage, thermally modified wood is heated to high temperatures, which changes the wood's chemical structure and makes it more resistant to decay and insects. This process also makes the wood more stable and resistant to warping, which can be a problem with other types of wood.

If you're looking for high-quality wood products that are both durable and environmentally friendly, Westwood Millworks is the best choice. Our thermally-treated wood products are made using sustainable practices, and we stand behind the quality of our products. Whether you're building a deck, a fence, or any other type of structure, we have the perfect wood products for your project.

Understanding Wood Treatments

When it comes to choosing the right wood for your project, it's important to understand the different treatments available. Two popular treatments are thermal modification and pressure-treated wood.

Thermal Modification Process

Thermal modification is a process that involves heating wood to high temperatures in a kiln or steam chamber. This process changes the chemical structure of the wood, making it more durable and resistant to decay, insects, and moisture. The heat treatment process also darkens the color of the wood.

At Westwood Millworks, we use state-of-the-art technology to thermally modify our wood products. Our process involves carefully controlling the temperature and humidity levels to ensure consistent results. Our thermally modified wood products are of the highest quality and are perfect for a wide range of applications.

Pressure-Treated Wood Treatment

Pressure-treated wood is another popular treatment that involves treating wood with preservative chemicals in a pressurized cylinder. This process helps protect the wood from decay, insects, and moisture. The preservative chemicals used in pressure-treated wood can vary, but they typically include copper, chromium, and arsenic.

While pressure-treated wood is a cost-effective option, it does have some drawbacks. The chemicals used in the treatment process can be harmful to the environment and can leach into the soil over time. Additionally, pressure-treated wood can warp or crack over time, especially if it's not properly maintained.

When it comes to choosing between thermal modification and pressure-treated wood, it's important to consider your specific needs and budget. At Westwood Millworks, we believe that our thermally modified wood products are the best option for those who want a high-quality, environmentally friendly, and long-lasting wood product.

Properties and Performance

Durability and Resistance

When it comes to durability and resistance to rot, thermally modified wood is superior to pressure-treated wood. The thermal modification process changes the wood's chemical structure, making it more resistant to decay and insect damage. This results in a longer lifespan, with thermally modified wood expected to last up to 30 years or more, compared to pressure-treated wood, which is expected to last around 20-30 years.

Dimensional Stability

Thermally modified wood also has superior dimensional stability compared to pressure-treated wood. The thermal modification process reduces the wood's ability to absorb moisture, which in turn reduces the wood's tendency to expand and contract. This results in a more stable product that is less prone to warping, twisting, or splitting.

Appearance and Aesthetics

Thermally modified wood has a unique appearance that sets it apart from pressure-treated wood. The thermal modification process changes the wood's natural color, resulting in a rich, warm tone that can range from a light brown to a deep reddish-brown. The wood also develops a natural resistance to gray fungi, which helps maintain its appearance over time.

When it comes to choosing between thermally modified and pressure-treated wood, it is important to consider the specific needs of your project. While pressure-treated wood may be a more affordable option, it may not offer the same level of durability and stability as thermally modified wood. Additionally, pressure-treated wood can be brittle and prone to cracking over time.

If you are looking for the best option for thermally modified wood products, Westwood Millworks is the ideal choice. Our thermally modified wood products are of the highest quality, offering superior durability, stability, and appearance. With Westwood Millworks, you can trust that you are getting the best possible product for your project.

Environmental and Health Considerations

Eco-Friendliness and Sustainability

When it comes to choosing between thermally modified and pressure-treated wood, eco-friendliness and sustainability are important factors to consider. Thermally modified wood is often considered a more sustainable option as it is produced using heat and steam, without the use of chemicals. The process results in a product that is more durable and resistant to decay and insect damage. Additionally, the production process does not generate any harmful byproducts, making it a more environmentally friendly option.

On the other hand, pressure-treated lumber is treated with chemicals to make it more resistant to decay and insects. The most common chemicals used for pressure treatment are CCA (chromated copper arsenate) and ACQ (alkaline copper quaternary). While these chemicals are effective in protecting the wood, they can leach out into the environment and pose a potential health risk. For this reason, pressure-treated wood is not recommended for use in areas where it may come into contact with food or drinking water.

Chemical Concerns

The chemical structure of thermally modified wood is altered through the use of heat and steam, resulting in a product that is more resistant to decay and insect damage. The process does not involve the use of chemicals, making it a safer and more environmentally friendly option. In contrast, pressure-treated wood is treated with chemicals that can be harmful to both human health and the environment. The chemicals used in pressure treatment can leach out of the wood and into the surrounding soil and water, posing a potential risk to plants, animals, and humans.

Westwood Millworks offers a range of thermally-treated wood products that are a safer and more environmentally friendly option compared to pressure-treated lumber. Our products are produced using heat and steam, without the use of chemicals, resulting in a product that is more durable and resistant to decay and insect damage.
