Pressure treated wood is a type of wood that has been treated with chemicals to increase its durability and resistance to rot, insects, and decay, which is important in the climate we experience in Markham, Ontario and beyond. In this blog post, we'll explore how pressure treated wood works and why it lasts longer than untreated wood.
How It Works:
The process of pressure treating wood involves placing the wood into a large cylinder that is then sealed and vacuumed to remove all air. Once the air has been removed, the cylinder is filled with a preservative solution under pressure. The pressure forces the solution deep into the wood fibers, allowing it to penetrate to the core of the wood. The wood is then left to dry, allowing the preservative to fully penetrate and bond to the wood fibers.
The chemicals used in pressure treated wood are typically a combination of copper, chromium, and arsenic or copper and azole compounds. These chemicals work by creating a barrier that protects the wood from rot and decay, as well as repelling insects and other pests.
Why It Lasts Longer:
Pressure treated fencing lasts longer than untreated wood because of its resistance to rot, decay, and insects. The chemicals used in pressure treating wood create a barrier that protects the wood from the elements and pests that can cause damage over time.
Additionally, it is often made from slower-growing trees that have tighter growth rings, which makes the wood denser and more durable. This, combined with the preservative treatment, makes pressure treated fences stronger and less susceptible to damage over time.
It's important to note that while pressure treated fencing is more durable than untreated wood, it still requires regular maintenance to keep it in good condition. This includes regular cleaning and applying a water repellent coating to help prevent moisture from penetrating the wood fibers.
