The Pressure Treating Process

So, what is pressure treated timber? This term refers to lumber that has undergone a specific treatment process to protect it from things like decay, insects, and environmental conditions. Here, we delve into the intricacies of the pressure treating process.

The primary goal of this process is to force preservatives into the wood, thereby enhancing its durability and resistance against harsh environments. It starts with placing the untreated timber in a sealed treatment cylinder. This cylinder is then evacuated of air, creating a vacuum. A preservative solution is then introduced into the cylinder under high pressure. This high-pressure environment forces the preservative deep into the cellular structure of the wood.

This is not a rapid process; it takes time for the treatment to penetrate deep into the lumber. The depth of penetration depends on factors such as wood species, its moisture content, and the type and concentration of preservative used. Once the desired level of penetration is achieved, excess preservative is removed from the cylinder, and then it is returned to atmospheric pressure.

Afterward, the treated timber is left to sit for a specific period (this can vary depending on the type of wood and preservative used). This allows excess fluid to drain off and helps the preservatives to fix properly within the wood fibers. In some cases, it may also be kiln-dried to reduce its moisture content and make it ready for use faster.

In essence, pressure treating is an effective way to lengthen the life of timber. It protects it from things that naturally break down wood: termites, beetles, fungi, and weathering. Pressure-treated timber is ideal for outdoor structures like decks, fences, and pergolas where weather resistance is key.

However, it’s worth noting that this treatment does not make timber invincible. Regular maintenance, like sealing or painting, is still necessary to ensure its longevity. But with pressure-treated timber, you get a head start in the fight against the elements and pests.
