Have you ever wondered why some fences stay straight for years while others start to twist or crack? The reason often comes down to the type of lumber used. When building a fence, deck, or home, it is important to understand the difference between green and kiln-dried lumber.
At Billboard Lumber Company, we help builders, farmers, and homeowners across Oregon choose the right type of wood for their projects. As one of the leading lumber manufacturers in Oregon, we know that the right lumber can make a project stronger, safer, and longer lasting.
What Is Green Lumber?
Green lumber is wood that has been freshly cut from a tree. It still holds a lot of water inside, sometimes half of its total weight. Because it has not been dried, green lumber is heavier and softer than dried wood. People sometimes use green lumber for construction or fencing because it costs less and is easier to cut at first. But there are a few things to know before choosing it.
As green lumber dries over time, it naturally shrinks. This can cause boards to bend, twist, or crack. If you build a fence using green wood, you might see small gaps form between the boards after a few months. For some short-term or low-cost projects, this might be fine, but it is not always the best choice for long-term use.
At Billboard Lumber Company, we offer green lumber as part of our reliable lumber services in Oregon for customers who want a more affordable option or prefer to let the wood dry naturally after installation. Our team can help you decide if green lumber fits your project.
What Is Kiln-Dried Lumber?
Kiln-dried lumber goes through a special drying process before it is sold. The wood is placed inside a large oven, called a kiln, where heat and air remove most of the water. The process usually reduces the moisture level to about 6 to 12 percent, depending on the type of wood and how it will be used.
This method makes the lumber lighter, stronger, and more stable. Because most of the water is gone, the boards are less likely to warp, crack, or shrink later. You can also paint, stain, or seal kiln-dried wood right away, which saves time during building.
At Billboard Lumber Company, our lumber services include high-quality kiln-dried lumber for construction, fencing, and custom wood projects. Each piece is carefully prepared to make sure it meets our quality standards.
Green vs Kiln-Dried Lumber: Key Differences
When comparing green vs kiln-dried lumber, it helps to look at what sets them apart in performance and cost.
1. Moisture Level
Green lumber contains a lot of water, while kiln-dried lumber has been dried to remove most of it. Drier wood is less likely to change shape over time.
2. Weight
Green lumber is heavier because of the water inside. Kiln-dried lumber is lighter and easier to move or install.
3. Durability
Kiln-dried wood lasts longer because it does not shrink or warp as much. Green wood might need more maintenance later.
4. Cost
Green lumber is usually cheaper to buy, but kiln-dried lumber may save money in the long run because it lasts longer and needs fewer repairs.
5. Appearance
Kiln-dried lumber has a smoother, cleaner finish, which makes it a good choice for fences, decks, and trim work.
The Benefits of Kiln-Dried Wood
There are many benefits of kiln-dried wood that make it a smart choice for construction and fencing.
· Stronger and more stable: Kiln drying locks the wood into shape so it does not bend or twist easily.
· Less risk of mold or rot: The drying process removes moisture that can cause decay.
· Better for nails and glue: Drier wood holds fasteners more securely.
· Ready to use: You can paint or stain kiln-dried lumber right away.
· Long-lasting value: It performs better and stays in good condition for many years.
At Billboard Lumber Company, we recommend kiln-dried lumber for most outdoor and structural projects because of its strength and reliability.
Frequently Asked Questions
1. What is the main difference between green and kiln-dried lumber?
Green lumber has high moisture content because it has not been dried. Kiln-dried lumber has had most of its moisture removed through a controlled heating process.
2. Why should I use kiln-dried lumber for construction or fencing?
The benefits of kiln-dried wood include greater strength, less warping, and longer life, making it ideal for outdoor and structural projects.
3. Can I still use green lumber for fencing?
Yes, but you should expect some movement as the wood dries. Kiln-dried lumber will stay straighter and maintain its shape better.
4. Does kiln-dried lumber cost more?
It may cost a little more at first, but it usually saves money over time by reducing maintenance and replacement costs.
