Pole Barn Board and Batten Siding: Green vs Dry Wood (5 Key Tips)

Do you remember the crisp scent of freshly cut wood, the rhythmic thud of an axe, and the satisfaction of stacking a winter’s worth of firewood? These are memories etched in my mind from years spent in the woods, learning the trade from my grandfather. But even with all that hands-on experience, I quickly realized that intuition only gets you so far. To truly excel in the wood industry, whether you’re building a pole barn, logging timber, or preparing firewood, you need to understand and track your project metrics. It’s about turning gut feelings into data-driven decisions.

This article is dedicated to understanding the nuances of using green versus dry wood for pole barn board and batten siding, specifically focusing on five key tips. We will delve into the importance of project metrics and key performance indicators (KPIs) in ensuring a successful outcome.

Pole Barn Board and Batten Siding: Green vs Dry Wood (5 Key Tips)

Building a pole barn with board and batten siding is a classic, cost-effective way to create a durable and attractive structure. Choosing between green (unseasoned) and dry (seasoned) wood for your siding is a critical decision that impacts the project’s longevity, appearance, and overall success. Let’s explore five key tips to help you make the right choice.

Tip #1: Understanding Wood Moisture Content (MC)

Definition: Wood Moisture Content (MC) refers to the amount of water present in wood, expressed as a percentage of the wood’s oven-dry weight.

Why It’s Important: MC is the foundation for understanding how wood behaves. Green wood has a high MC (often above 30%), while dry wood has a lower MC (typically between 6-12% for interior applications and 12-18% for exterior applications). This difference significantly affects wood’s dimensional stability, weight, and susceptibility to decay.

How to Interpret It: A high MC indicates that the wood is still “wet” and prone to shrinking, warping, and potential decay. A low MC indicates that the wood has been seasoned, making it more stable and less susceptible to these issues.

How It Relates to Other Metrics: MC is directly related to the time required for seasoning (drying) wood, the potential for wood waste due to shrinkage, and the overall cost of the project.

My Experience: I once built a small shed using green pine for the siding because I was in a hurry and the price was right. Big mistake! Within a few months, the boards had shrunk considerably, leaving large gaps between them. Rain and insects quickly found their way in, and the shed deteriorated rapidly. I learned the hard way that understanding MC is crucial.

Actionable Insight: Always measure the MC of the wood you’re considering using for siding. A simple moisture meter is an invaluable tool. Don’t rely on visual inspection alone.

Tip #2: Shrinkage and Movement Considerations

Definition: Shrinkage refers to the dimensional change in wood as it dries, while movement refers to the ongoing expansion and contraction of wood due to changes in humidity.

Why It’s Important: Green wood shrinks as it dries, which can lead to gaps in your siding, loose nails, and an overall unattractive appearance. Dry wood, while more stable, still expands and contracts with changes in humidity. Understanding these movements is crucial for proper installation.

How to Interpret It: Significant shrinkage indicates that green wood was used and wasn’t properly acclimated. Excessive movement in dry wood suggests that the siding wasn’t installed with enough allowance for expansion and contraction.

How It Relates to Other Metrics: Shrinkage and movement are directly related to the initial MC of the wood, the type of wood used (some species shrink more than others), and the installation techniques employed.

My Experience: On a larger pole barn project, I used kiln-dried pine for the siding. Even though it was dry, I still left small gaps between the boards during installation to accommodate expansion. Over the seasons, those gaps have opened and closed slightly, but the siding has remained tight and secure.

Data-Backed Insight: According to the USDA Forest Products Laboratory, radial shrinkage (perpendicular to the growth rings) is typically less than tangential shrinkage (along the growth rings). This means that flat-sawn boards (with growth rings running parallel to the face) will shrink more across their width than quarter-sawn boards (with growth rings running perpendicular to the face).

Actionable Insight: When using dry wood, leave small gaps between the boards during installation to accommodate expansion and contraction. The size of the gap will depend on the width of the boards and the expected humidity fluctuations in your area. For green wood, overlapping the boards is often necessary to account for substantial shrinkage.

Tip #3: Decay and Insect Resistance

Definition: Decay refers to the decomposition of wood caused by fungi, while insect resistance refers to wood’s ability to withstand attack from wood-boring insects.

Why It’s Important: Green wood is highly susceptible to decay and insect infestation. The high MC provides a perfect environment for fungi and insects to thrive. Dry wood, especially if treated with preservatives, is much more resistant.

How to Interpret It: Signs of decay include discoloration, softness, and a musty odor. Signs of insect infestation include small holes, sawdust, and the presence of insects.

How It Relates to Other Metrics: Decay and insect resistance are directly related to the MC of the wood, the type of wood used (some species are naturally more resistant than others), and the presence of preservatives.

My Experience: I once salvaged some green oak logs from a fallen tree, intending to use them for barn beams. I didn’t realize how quickly decay could set in. Within weeks, the logs were covered in mold and the wood was starting to soften. I had to discard them, a costly and disappointing experience.

Data-Backed Insight: Certain wood species, like cedar, redwood, and black locust, are naturally resistant to decay and insects due to the presence of natural oils and extractives. These species are often a good choice for siding, especially in damp climates.

Actionable Insight: If using green wood, consider treating it with a preservative to prevent decay and insect infestation. Borate preservatives are a good option, as they are effective and relatively non-toxic. When using dry wood, ensure it is properly treated or choose a naturally resistant species.

Tip #4: Installation Techniques

Definition: Installation techniques refer to the methods used to fasten the siding boards to the pole barn frame.

Why It’s Important: The correct installation technique is crucial for ensuring the siding is secure, weatherproof, and aesthetically pleasing. Different techniques are required for green and dry wood.

How to Interpret It: Improper installation can lead to loose boards, gaps, water leaks, and an overall unprofessional appearance.

How It Relates to Other Metrics: Installation techniques are directly related to the MC of the wood, the type of wood used, and the desired aesthetic.

My Experience: I’ve seen countless examples of poorly installed siding, often due to a lack of understanding of wood movement. One common mistake is using nails that are too short or too thin, which allows the boards to pull away from the frame as they shrink or expand.

Actionable Insight: When using green wood, overlap the boards to account for shrinkage. Use galvanized nails or screws to prevent corrosion. Consider using a “slip joint” where the batten is attached to only one board, allowing for movement. When using dry wood, leave small gaps between the boards and use appropriately sized fasteners. Pre-drilling pilot holes can help prevent splitting.

Detailed Installation Techniques for Green Wood Siding:

• Overlapping Boards: This is crucial for green wood. The amount of overlap will depend on the expected shrinkage of the wood species. A general rule of thumb is to overlap the boards by at least 1 inch for every 6 inches of board width.
• Fastener Selection: Use galvanized nails or screws that are long enough to penetrate at least 1.5 inches into the pole barn frame. The fasteners should also be corrosion-resistant to withstand the moisture in the green wood. Ring-shank nails provide better holding power than smooth-shank nails.
• Slip Joints: A slip joint allows the siding boards to move independently of each other. This can be achieved by attaching the batten to only one board, typically the top board. The batten then “slides” over the adjacent board as the wood shrinks or expands.
• Acclimation (If Possible): While not always practical, allowing green wood to air-dry for a period before installation can reduce the amount of shrinkage that occurs after installation. This can be done by stacking the boards in a well-ventilated area, with stickers (small pieces of wood) between each board to allow for air circulation.

Detailed Installation Techniques for Dry Wood Siding:

• Gaps Between Boards: Leave small gaps (typically 1/8 to 1/4 inch) between the boards to allow for expansion and contraction. The size of the gap will depend on the width of the boards and the expected humidity fluctuations.
• Fastener Selection: Use galvanized nails or screws that are long enough to penetrate at least 1.5 inches into the pole barn frame. Pre-drilling pilot holes can help prevent splitting, especially when working with hardwoods.
• Proper Spacing: Ensure that the battens are properly spaced to provide adequate support for the siding boards. The spacing will depend on the thickness of the siding boards and the wind load in your area.
• Sealing End Grain: Sealing the end grain of the siding boards can help prevent moisture absorption and reduce the risk of decay. This can be done with a paintable sealant or a wood preservative.

Tip #5: Cost Analysis

Definition: Cost analysis refers to the process of evaluating the total cost of using green versus dry wood, including the cost of materials, labor, and potential future repairs.

Why It’s Important: The initial cost of green wood is often lower than that of dry wood. However, the long-term costs can be higher due to increased labor for installation, the potential for wood waste, and the risk of premature failure.

How to Interpret It: A low initial cost may be offset by higher long-term costs. A higher initial cost may result in lower long-term costs.

How It Relates to Other Metrics: Cost analysis is directly related to the MC of the wood, the type of wood used, the installation techniques employed, and the expected lifespan of the siding.

My Experience: I once compared the cost of using green pine versus kiln-dried cedar for a siding project. The green pine was significantly cheaper upfront, but the labor costs were higher due to the need for overlapping boards and the increased risk of waste. In the end, the kiln-dried cedar, while more expensive initially, proved to be the more cost-effective option due to its durability and ease of installation.

Data-Backed Insight: According to a study by the University of Minnesota Extension, the cost of drying lumber can range from $0.10 to $0.50 per board foot, depending on the drying method and the species of wood. This cost needs to be factored into the overall cost analysis.

Actionable Insight: Perform a thorough cost analysis before making a decision. Consider the cost of materials, labor, potential waste, and future repairs. Factor in the expected lifespan of the siding and the cost of maintenance. Don’t just focus on the initial price tag.

Detailed Cost Breakdown Example:

Let’s consider a hypothetical pole barn siding project requiring 1,000 board feet of lumber.

Scenario 1: Green Pine

• Material Cost: $1.50 per board foot = $1,500
• Labor Cost (Installation): $2.00 per board foot (due to overlapping and potential fitting issues) = $2,000
• Waste Factor: 10% (due to warping and splitting) = $150 (cost of replacing wasted lumber)
• Preservative Treatment: $0.50 per board foot = $500
• Total Cost: $1,500 + $2,000 + $150 + $500 = $4,150

Scenario 2: Kiln-Dried Cedar

• Material Cost: $3.00 per board foot = $3,000
• Labor Cost (Installation): $1.50 per board foot (easier installation, less fitting) = $1,500
• Waste Factor: 2% (higher quality, less warping) = $60 (cost of replacing wasted lumber)
• Preservative Treatment: $0 (naturally decay-resistant)
• Total Cost: $3,000 + $1,500 + $60 = $4,560

In this example, while the kiln-dried cedar has a higher initial material cost, the lower labor cost and reduced waste factor make it a more competitive option. Furthermore, the lack of need for preservative treatment further closes the gap. Over the long term, the cedar’s natural decay resistance will likely result in lower maintenance and repair costs.

Tracking Project Metrics for Success

Now that we’ve covered the five key tips for choosing between green and dry wood for pole barn siding, let’s delve into the importance of tracking project metrics and KPIs in ensuring a successful outcome.

Why Track Project Metrics?

Tracking project metrics is crucial for several reasons:

• Improved Decision-Making: Data-driven decisions are always better than gut feelings. Metrics provide concrete evidence to support your choices.
• Cost Control: Tracking costs allows you to identify areas where you can save money and improve efficiency.
• Time Management: Monitoring timelines helps you stay on schedule and avoid delays.
• Quality Assurance: Measuring quality ensures that your work meets the required standards.
• Continuous Improvement: Analyzing past projects allows you to identify areas for improvement in future projects.

Key Project Metrics and KPIs

Here are some key project metrics and KPIs that I track on my wood processing and firewood preparation projects:

1. Material Cost per Board Foot:

   • Definition: The total cost of lumber (green or dry) divided by the number of board feet purchased.
   • Why It’s Important: Provides a clear understanding of material expenses, allowing for comparison between different wood types and suppliers.
   • How to Interpret It: A higher cost per board foot might indicate the need to explore alternative suppliers or wood species.
   • How It Relates to Other Metrics: Directly impacts the overall project cost and can influence decisions about wood selection.
   • Example: I recently sourced green pine at $1.50 per board foot versus kiln-dried cedar at $3.00 per board foot. The initial cost difference was significant, but I needed to factor in other costs like labor and treatment.

2. Labor Hours per Square Foot of Siding Installed:

   • Definition: The number of labor hours required to install one square foot of siding.
   • Why It’s Important: Measures the efficiency of the installation process.
   • How to Interpret It: A high number of labor hours may indicate the need for improved installation techniques or better equipment.
   • How It Relates to Other Metrics: Directly impacts the overall project cost and can be influenced by the type of wood used (green wood often requires more labor due to fitting issues).
   • Example: On a recent project using kiln-dried pine, my team averaged 0.25 labor hours per square foot. On a previous project using green oak, the average was 0.40 labor hours per square foot due to the difficulty of working with warped boards.

3. Wood Waste Percentage:

   • Definition: The percentage of lumber that is wasted during the installation process due to cuts, warping, or splitting.
   • Why It’s Important: Measures the efficiency of material usage and identifies areas where waste can be reduced.
   • How to Interpret It: A high waste percentage indicates the need for improved cutting techniques or better material handling practices.
   • How It Relates to Other Metrics: Directly impacts the overall project cost and can be influenced by the quality of the lumber and the skill of the installers.
   • Example: I implemented a new cutting strategy on a recent project that reduced our wood waste percentage from 8% to 3%, resulting in significant cost savings.

4. Moisture Content (MC) Variation:

   • Definition: The range of moisture content levels within a batch of lumber.
   • Why It’s Important: Ensures consistency in wood stability and prevents issues related to shrinkage and warping.
   • How to Interpret It: A wide variation in MC indicates inconsistent drying or poor storage practices.
   • How It Relates to Other Metrics: Directly impacts the quality of the finished product and can influence the choice between green and dry wood.
   • Example: I rejected a batch of kiln-dried lumber because the MC varied from 8% to 18%. This inconsistency would have led to uneven shrinkage and warping after installation.

5. Customer Satisfaction Score:

   • Definition: A measure of customer satisfaction with the finished project.
   • Why It’s Important: Provides feedback on the overall quality of the work and identifies areas for improvement.
   • How to Interpret It: A low customer satisfaction score indicates the need to address customer concerns and improve the quality of the work.
   • How It Relates to Other Metrics: Reflects the overall success of the project and can be influenced by factors such as material quality, installation techniques, and adherence to timelines.
   • Example: I implemented a post-project survey to gather customer feedback and identified several areas where we could improve our communication and project management.

Case Study: Comparing Green vs. Dry Wood Siding Projects

To illustrate the importance of tracking these metrics, let’s compare two hypothetical pole barn siding projects:

Project A: Green Pine Siding

• Material Cost: $1.50 per board foot
• Labor Hours: 0.40 hours per square foot
• Wood Waste: 10%
• MC Variation: 25% – 35%
• Customer Satisfaction: 7/10

Project B: Kiln-Dried Cedar Siding

• Material Cost: $3.00 per board foot
• Labor Hours: 0.25 hours per square foot
• Wood Waste: 3%
• MC Variation: 10% – 12%
• Customer Satisfaction: 9/10

Analysis:

• Project B had a higher material cost but lower labor hours and wood waste.
• The MC variation was much lower in Project B, indicating better quality control.
• Customer satisfaction was significantly higher in Project B, likely due to the improved quality and appearance of the finished product.

Conclusion:

While Project A had a lower initial material cost, the higher labor hours, wood waste, and MC variation resulted in a lower overall value and a less satisfied customer. Project B, despite its higher material cost, proved to be a better investment in the long run.
