Kiln-dried lumber has been gaining popularity over the years because of its composition, durability, and price. The process for drying wood consists of placing the wood in a large kiln and burning it in order to reach a stable moisture content. While the process is one of the more destructive to the structure of the tree itself, kiln-dried products can offer advantages that cannot be found elsewhere.
Read more in this article about the advantages and disadvantages of using kiln-dried lumber, how to choose the right type for your project, and where to find it.
What is Kiln Dried Lumber
You want to build a deck and you’ve decided to use cedar but you’ve heard that “kiln dried” is much better. So, what is kiln-dried wood and why should you choose it for your project? Kiln-dried lumber, also known as kiln-dried timber, is wood that has been dried in a controlled environment using heated air.
kiln-dried wood is one of the most effective ways to make sure wood retains its splinter-free, long-lasting character. Though it’s proven in countless situations, where space and budget are concerns, kiln-dried wood is often overlooked. If you are interested in wood that will stand the test of time, kiln-dried lumber is worth considering.
Advantage of kiln Dried Lumber
The kiln-dried wood process helps to remove any moisture from the wood and prevent warping or cracking during the building process. In addition to reducing the chance of damage, kiln-dried lumber also has a more consistent moisture content throughout the wood, making it easier to work with and increasing its durability.
Using kiln-dried wood for your projects can result in a better-finished product as it is less likely to warp or shrink over time. It also allows for easier and more precise measurements during the building process, resulting in a stronger and longer-lasting structure.
One of the main benefits of using kiln-dried wood is its ability to resist warping and cracking. The heat and pressure used in the drying process helps stabilize the wood’s moisture content, making it less susceptible to changes in humidity and temperature. This can also lead to a longer lifespan for your finished project.
Using kiln-dried lumber for building projects can result in higher quality and longer-lasting end results. It may come at a slightly higher cost, but the benefits are worth it in the long run. So when starting your next project, consider investing in kiln-dried wood for a better-finished product.
What is a Kiln for wood?
The kiln process involves drying wood in a space where airflow, relative humidity, and temperature can be regulated. This allows for the reduction of wood moisture content of kiln-dried lumber to a specific level while preventing any drying faults. Conventional and dehumidification kilns are the most frequently utilized kilns.
In a conventional kiln, heated air is circulated through the kiln to remove moisture from the wood. In a dehumidification kiln, cool air is passed through a chamber where it absorbs moisture before being reheated and circulated back into the kiln. The end result in both cases is a more stable and durable product that can resist warping and cracking. It also allows for more precise measurements during building projects, resulting in improved quality and longevity.
What is Kiln Dried Lumber used for?
Kiln-dried lumber is used in a variety of building projects, including home construction, furniture making, and deck building. Its stability and durability make it a preferred choice for high-quality projects that require precise measurements and want to avoid warping or cracking over time. It can also be used in interior design, such as flooring and shelving. In general, any project that requires high-quality and long-lasting wood can benefit from using kiln-dried wood.
Frequently Asked Questions
How long do you need to kiln dry wood?
The amount of time needed to kiln dry wood varies depending on the wood’s type and moisture content and the drying method used. On average, it can take anywhere from several days to weeks to fully dry and stabilize the wood in a kiln.
The resins in softwoods are removed by the heat in the kiln. Depending on the type of wood, air-drying is a natural process that can take anywhere from 8 to 16 months. On the other hand, kiln-drying typically takes 6 to 8 weeks. There are no internal tensions introduced into the wood during this operation.
What temperature do you kiln dry wood at?
The temperature used in the kiln drying process depends on the type of wood being dried and its initial moisture content. Generally, temperatures range from 120-190 degrees Fahrenheit (240 degrees Celsius). The key is to slowly and steadily remove moisture from the wood without causing any damage or drying faults.
The specific temperature will vary depending on the type of wood being dried. It is important to properly monitor the moisture content of the wood during the drying process to ensure that it does not get overheated and damaged. Furthermore, the drying time will also vary based on the initial moisture content and thickness of the wood. Overall, it is best to consult a professional for proper kiln drying guidelines for your specific type of wood.
What is the difference between Kiln dried lumber vs green lumber?
Kiln-dried lumber has had its moisture content reduced through the controlled drying process in a kiln, while green lumber still retains some moisture. As a result, kiln-dried lumber is more stable and less likely to warp or shrink compared to green lumber.
However, it may also come at a higher cost due to the added processing time and equipment needed. In some cases, green lumber may be preferred for certain projects that require a higher moisture content. It is important to consider the specific project and desired end result when choosing between kiln dried and green lumber.
How much does it cost to kiln dry lumber?
The cost of kiln-drying lumber can vary depending on the amount and type of wood being dried, as well as the specific drying method and equipment used. On average, it can cost around $1-$2 per board foot for kiln drying services.
Additionally, buying kiln-dried lumber from a kiln-dried lumber supplier may also be slightly more expensive than green lumber. However, many professionals and consumers find that the added cost of kiln-dried lumber is worth it in the long run for improved stability and durability of their finished project.
What are the disadvantages of kiln drying?
Some potential disadvantages of kiln drying include higher cost and longer processing time compared to air drying, the risk of drying faults due to improper or inconsistent temperature and humidity control, and the need for specialized equipment. However, many woodworkers feel that the benefits outweigh the disadvantages, as kiln-dried lumber offers improved stability and durability in their finished projects.
Additionally, some drying faults that result from improper kiln drying may be challenging to spot with the unaided or untrained eye. Case-hardening and honeycombing are two examples. These flaws typically make the lumber unsuitable for the majority of good woodworking and can be dangerous to work with in some circumstances.
Conclusion
Kiln drying offers a controlled and efficient method of removing moisture from the wood. This can result in improved stability and durability in finished projects, but it also comes with added cost and the risk of drying faults. It is important to consider the type of wood, desired end result, and cost when deciding whether to use kiln-dried or green lumber.
