Introduction to Green Treated Lumber
Before we delve into the depths of this blog post, let’s first answer the question, ‘What is green treated lumber?’
Green treated lumber, also referred to as pressure-treated lumber, is a type of wood that has been infused with chemical preservatives. These chemicals are designed to fend off damage from moisture, fungi, and insects – three of the primary culprits behind the deterioration of wood. The ‘green’ tag comes from the slight greenish hue that these chemicals impart to the wood. While it’s not exactly eco-friendly as the name might suggest, it does contribute significantly to prolonging the lifespan of the wood.
The process involves placing untreated wood in a large cylindrical holding tank. The tank is then filled with a liquid preservative before being sealed and subjected to high pressure. This pressure forces the chemical solution deep into the core of the wood, making it resistant to pests, rot, and decay. The result is a durable and robust product that can be utilized for an array of outdoor applications such as decking, fencing, and landscaping projects where durability and longevity are key considerations.
Now you might wonder about the safety aspects related to using chemically-treated woods. It’s a valid concern indeed. However, over time, improvements have been made in choosing safer chemicals for the treatment process. For instance, chromated copper arsenate (CCA), which was previously used for treating woods but raised health concerns due to its arsenic content, has been replaced by less toxic alternatives like Alkaline Copper Quaternary (ACQ), Copper Azole (CA), or Micronized Copper Azole (MCA).
It’s essential to note that while green treated lumber is more durable than untreated wood, it does require some safety precautions during handling and installation. It’s always advisable to wear gloves when handling green treated lumber and to wash hands thoroughly after contact. Also, any cut-offs or sawdust should be disposed of properly and should never be used in compost or mulch.
In the sections that follow, we will delve deeper into the benefits and drawbacks of using green treated lumber, explore its various uses, and provide some tips for handling and installation. So, whether you’re a seasoned contractor, a DIY enthusiast, or someone simply considering a home improvement project, read on to gain insights on this time-tested building material.
The Process of Green Treating Lumber
So, what is green treated lumber? Green treated lumber, also known as pressure-treated lumber, is a type of wood that has undergone a treatment process to enhance its durability and resistance to insects, mold, and fungal decay. The “green” in green treated lumber refers to the color that the wood takes on after the treatment process, not to any environmental credentials it may have. This process makes the wood more suitable for outdoor uses such as decks, fences, and landscaping projects where the wood is exposed to moisture and pests.
The process of green treating lumber involves several steps. Here’s a brief overview of how it works:
1. Preparation
The first step in the treatment process involves preparing the lumber. This typically involves drying the wood to remove any moisture. The moisture content of the wood needs to be below 20% before it can undergo pressure treatment.
2. Pressure Treatment
Once the lumber is dry, it’s placed into a large cylinder known as a retort. The retort is then sealed and filled with a preservative solution containing copper compounds and biocides – these give the treated lumber its characteristic green color and protect against pests and decay.
3. Vacuum and Pressure Application
After the retort is filled with the preservative solution, a vacuum is created inside the cylinder which pulls out air from the wood fibers and allows for deeper penetration of the solution into the wood. Then, pressure is applied to force the preservative deep into the heartwood of each piece of lumber. This ensures that all parts of the wood receive adequate treatment.
4. Drying & Finishing
After the pressure treatment, the lumber is removed from the retort and left to dry. This allows excess moisture and preservative solution to drain off. The treated wood is then ready to be used for outdoor construction projects.
It’s important to note that green treated lumber should not be confused with sustainably sourced or eco-friendly lumber. While the treatment process does make wood more durable and resistant to decay, it also involves using chemicals that can be harmful if not handled correctly. Always take appropriate precautions when working with green treated lumber.
