This treatment is designed to protect the wood from common issues such as decay and insect damage, thereby extending its life and usefulness.

So how does this process work? The first step in pressure treating wood involves placing the wood in a depressurized holding tank that removes the air and replaces it with a preservative. The specific type of preservative used varies, but it’s generally a chemical solution designed to resist termites, fungi, and other pests. This pressurization forces the chemical into the layers of the wood, ensuring thorough coverage throughout.

Once the pressurization process is complete, the wood is removed from the tank and left to dry. During this time, excess preservative drips off while the rest soaks deeper into the wood. Depending on the specific requirements of the project, different drying techniques might be employed. For instance, kiln-drying might be used for indoor projects where reduced moisture content is important.

The end result is a piece of lumber that’s highly resistant to environmental factors and can last for decades without suffering significant damage. It’s important to note that while pressure-treated wood does offer considerable benefits in terms of durability and longevity, it also requires proper handling and disposal because of the chemicals used in its treatment.

Now that we’ve answered ‘what does pressure treated wood mean’, it’s also worth knowing its applications.
