Introduction to Pressure Treated Wood
If you have ever embarked on a construction project involving wood, you may have come across the term ‘pressure treated’. But what does pressure treated mean, and why is it important to know? The pressure treatment process is a method used to prolong the life of wood and protect it against rot, insects, and environmental conditions.
Pressure treated wood is timber that has undergone a process where it is placed into a large cylindrical holding tank. The tank is then filled with a liquid preservative before extreme pressure is applied to force the chemicals deep into the core of the wood. This pressure treatment penetrates deeper than any paint or sealant ever could, which in turn provides long-term protection against harmful elements.
The main objective of this method is to extend the durability and lifespan of the wood products. Without this type of treatment, woods like pine or spruce are prone to decay when exposed to moisture or if they’re in direct contact with the ground. By using pressure treated wood for structures like decks, outdoor furniture, fencing, and playsets, you ensure that these installations become more resistant to nature’s harsh conditions and potentially destructive insects.
Because safety is a primary concern in any building project, choosing pressure-treated wood also means complying with many building codes. For instance, in regions where termite infestation is common, constructing homes and other buildings often requires the use of pressure-treated lumber for structural parts that are close to the ground. It’s an essential step for creating safe, strong, and durable structures.
However, it’s also important to note that not all types of wood require pressure treatment. Hardwoods like cedar and redwood naturally resist rot and insects but can be more expensive than their treated counterparts. So it’s crucial to consider the specific requirements and budget for your project before deciding what type of wood to use.
In conclusion, ‘what does pressure treated mean’ is a fundamental question to ask when engaging in any woodworking or construction project. Understanding the process and benefits of pressure treatment can ensure the longevity and safety of your structure, saving you time, money, and potential frustration in the long run.
The Process of Pressure Treating Wood
Pressure-treated wood is a popular choice for outdoor projects like decks, fences, and playground sets. But what does pressure treated mean? The process of pressure treating wood involves infusing it with chemicals to protect it against the elements, bugs, and decay.
To begin the process, untreated wood is placed into a large cylindrical holding tank. The tank is then sealed, and vacuum pressure is applied to remove all the air from the tank and the cells of the wood. This vacuum pressure creates a void in the cells which helps to pull the preservative into the wood.
Once all the air has been removed from the tank, a solution of water and preservatives is pumped in. The amount and type of preservative used depend on the intended use of the wood. Most commonly, a solution containing copper, which acts as a pesticide, and a fungicide is used.
The next stage is to apply high pressure to force the chemical solution deep into the wood. The high pressure ensures that the preservative penetrates deep into the heartwood and not just on the surface. This application method creates protection that’s integral to the wood and not just on its surface.
After this process is complete, the tank is then drained of this preservative solution. Another round of vacuum pressure may be applied to remove excess preservative on the surface of the wood. Finally, the treated wood needs to be left for several days or even weeks to dry out, depending on local weather conditions and indoor or outdoor drying facilities.
What does pressure treated mean for you as a user? In summary, pressure-treated wood provides long-lasting durability against outdoor elements, insects, and decay – making it an ideal choice for projects exposed to harsh conditions or where durability is required.
Remember though, while pressure treating does increase its resistance considerably, regular maintenance of the wood is still necessary. This could mean re-sealing the wood every few years, and checking regularly for any visible signs of wear or decay.
Understanding the pressure treating process gives you a better understanding of how this wood can serve your needs, and ensure you get the maximum value out of your outdoor wooden structures.
