Types of Wood Treatments
When discussing lumber, a common question arises: What is treated lumber treated with? The treatment of lumber involves the use of various chemicals meant to preserve the wood and prolong its life. Different types of wood treatments are commonly used based on the specific requirements and desired use of the wood. Here we will explore some of these treatments.
Pressure Treatment:
The most common type of wood treatment is pressure treatment. In this process, the wood is placed in a vacuum chamber where air and moisture are removed. The wood is then exposed to a preservative under high pressure which penetrates deep into the wood fibers. This treatment helps to protect the wood from fungal decay and insect infestation. Pressure-treated wood is typically used for applications where the wood will be in direct contact with the ground or open to the elements such as decking, fences, and playground equipment.
Water-Borne Treatment:
Another type of treatment is water-borne treatment. Water-based preservatives are applied to the wood, often containing copper or boron compounds. These treatments are less toxic than others, making them suitable for indoor uses and for structures like vegetable gardens where food safety may be a concern. Despite their lower toxicity levels, they still provide strong protection against decay and insect damage.
Oil-Based Treatment:
Oil-based treatments are another option for treating lumber. These involve the use of heavy oils that carry preservative chemicals into the wood. Some commonly used oil-based preservatives include Creosote and Pentachlorophenol. Oil-based treatments provide excellent waterproofing and are typically used for utility poles, railroad ties, and other heavy-duty outdoor applications.
Fire Retardant Treatment:
A fire retardant treatment reduces the flammability of the wood. These treatments are typically water-based solutions that contain fire retardant chemicals. They provide the wood with a Class A fire rating and are often used in construction projects where a high level of fire resistance is needed.
In conclusion, the answer to “What is treated lumber treated with?” largely depends on the intended use of the wood. Each type of treatment comes with its own benefits and considerations, so it’s important to choose the right one based on your specific needs.
Chemicals Used in Treated Lumber
Ever asked yourself, ‘What is treated lumber treated with?’ Well, the answer lies in a mixed bag of chemicals used to enhance the durability and resistance of the wood. These chemicals are designed to protect the wood from threatening elements like termites, fungi, and other wood-boring insects, as well as environmental elements such as moisture. The treatment process involves infusing these chemicals into the lumber under high pressure—a process known as pressure treatment.
The specific types of chemicals used can vary depending on the intended use of the wood, but there are some common ones utilized throughout the industry. One of these is Chromated Copper Arsenate (CCA), which was widely used for many years due to its effectiveness. However, due to environmental and health concerns related to arsenic, the residential use of CCA-treated wood has significantly decreased since 2003.
Today, Alkaline Copper Quaternary (ACQ) and Copper Azole (CA-B) are widely used alternatives to CCA. They offer similar levels of protection without the harmful arsenic component. Both ACQ and CA-B contain copper, which deters insects and fungi. The difference lies in their secondary components; ACQ uses a quaternary compound as a co-biocide, while CA-B uses an organic triazole compound known as tebuconazole or propiconazole.
In addition to these, Micronized Copper Azole (MCA) is also commonly used in treating lumber. This particular type of treatment involves the use of micron-sized particles of copper and an azole co-biocide. The small size of the particles allows for a more uniform distribution throughout the wood, which aids in protecting it from decay and insect damage.
Borate treated lumber is another popular option, particularly in areas prone to insect infestations. Borate is highly effective against termites, beetles, and other wood-boring insects, as well as fungal decay. An added advantage of borate-treated wood is that it is less corrosive to metal fasteners than some other treatments.
It’s essential to understand what your lumber has been treated with to ensure it’s safe for your intended use and to maintain the longevity of your project. Remember to always handle treated lumber safely, following all recommended guidelines to protect yourself and the environment.
The Treatment Process
The process of treating lumber is an intricate one that ensures the wood you use for your various projects is durable, long-lasting and resistant to external factors. So, what is treated lumber treated with? The answer lies in a mixture of chemicals that help fortify the wood and prolong its useful life.
The treatment process begins with the wood being carefully cleaned and stripped of any bark or residue that might interfere with the treatment. Once it’s clean, the wood is stacked inside a large cylinder, which is then sealed shut. With the wood inside, a vacuum removes all the air from the cylinder and from within the fibers of the wood itself.
Next, under pressure, the cylinder is filled with a liquid preservative. This chemical solution often contains components such as copper, which provides resistance to insects and fungi, and a fungicide like tebuconazole or propiconazole. This combination makes it more challenging for organisms to feed on or degrade the wood.
Afterwards, pressure is applied to force these chemicals deep into the layers of wood. The amount of pressure can vary greatly depending on the intended use of the lumber. For instance, wood that’s meant for ground contact requires higher levels of preservatives than those used above ground.
The final step in the treatment process is drying. The treated wood is removed from the cylinder and allowed to sit until most of the preservative has been absorbed into the timber. The leftover liquid on the surface evaporates over time; this could take several days or weeks depending on conditions like temperature and humidity.
The result of this thorough process is treated lumber – strong, durable wooden planks that have been specially treated to resist rot, decay and insect infestation. It’s important to note that while these chemicals provide significant benefits in terms of durability and longevity, they also mean that treated lumber should be handled with care, using gloves and dust masks. Always remember to wash your hands after handling treated lumber and never burn it as it can release toxic fumes.
So, the answer to ‘what is treated lumber treated with?’ involves a combination of vacuum pressure technology and chemical preservatives. The treatment process ensures that the wood you use for your projects, be it a beautiful deck or a sturdy fence, will stand the test of time.
