Protection from environmental elements is the primary attribute of an effective wood pile tarp, and understanding the nuances of size and material is crucial for preserving firewood quality. Firewood moisture content directly impacts its BTU (British Thermal Unit) output, and a properly sized and durable tarp, unlike a flimsy plastic sheet, mitigates moisture absorption. Organizations like the USDA Forest Service offer guidelines on firewood storage, emphasizing the importance of adequate covering to prevent rot and insect infestation. Consumers often face the dilemma of choosing between canvas and polyethylene, two common materials with varying degrees of water resistance and breathability for a wood pile tarp, further highlighting the need for informed decision-making.
Wood Pile Tarp: Choosing the Right Size & Material
Protecting firewood from the elements is crucial for ensuring it’s ready to burn efficiently when you need it. A quality "wood pile tarp" is a vital investment. However, not all tarps are created equal. Selecting the correct size and material is essential to effectively safeguard your woodpile. This article will guide you through the key considerations to make the right choice.
I. Understanding the Importance of a Wood Pile Tarp
Before diving into specifics, let’s clarify why a dedicated tarp is so important.
- Protection from Rain and Snow: Excess moisture makes wood difficult to ignite and reduces its burning efficiency. Wet wood also produces more smoke and creosote, increasing the risk of chimney fires.
- Preventing Rot and Decay: Constant exposure to moisture encourages the growth of mold and fungus, leading to rot and decay. A tarp keeps the wood dry, extending its lifespan.
- Improved Burning Efficiency: Properly seasoned (dried) wood burns hotter and cleaner. A tarp helps maintain dryness throughout the seasoning process and beyond.
II. Determining the Correct Tarp Size
Choosing the right size of "wood pile tarp" is paramount. An improperly sized tarp will leave parts of your woodpile exposed or be unwieldy and difficult to secure. Here’s how to calculate the optimal dimensions:
-
Measure Your Woodpile: Accurately measure the length, width, and height of your stacked woodpile.
-
Account for Overlap: Add extra length and width to these measurements to allow for sufficient overlap on all sides. A minimum of 1 foot of overlap on each side is recommended to provide adequate protection from wind-driven rain and snow. For areas with heavy winds, consider even more overlap.
-
Consider the Tarp’s Shape: Do you need a square, rectangular, or potentially even a custom-shaped tarp? Most woodpiles are rectangular, but consider any unique shapes in your wood storage area.
-
Calculating Required Dimensions:
- Tarp Length = Woodpile Length + (2 x Overlap)
- Tarp Width = Woodpile Width + (2 x Overlap)
Example: If your woodpile is 8 feet long, 4 feet wide, and you want a 1-foot overlap on each side, you’ll need a tarp that is (8 + (2 x 1)) = 10 feet long and (4 + (2 x 1)) = 6 feet wide. A 10′ x 6′ tarp would be appropriate.
-
Consider that only covering the top is an option for some people with a natural cover from the elements. In those cases, only length and width will be factors.
III. Exploring Tarp Materials
The material of your "wood pile tarp" significantly impacts its durability, water resistance, and overall effectiveness. Key factors to consider include the denier (thread thickness), weave density, and any coatings.
Here’s a comparison of common tarp materials:
| Material | Pros | Cons | Best Use Cases |
|---|---|---|---|
| Polyethylene (PE) | Lightweight, affordable, water-resistant, widely available. | Can be prone to tearing, lower UV resistance, may not withstand extreme weather conditions. | Temporary woodpile covers, use in mild climates, cost-effective option for seasonal protection. |
| Polypropylene (PP) | Stronger than PE, resistant to chemicals, good tear resistance. | Lower UV resistance than PE, can become brittle in cold temperatures. | More durable than PE for general woodpile protection, suitable for moderate climates. |
| Canvas | Breathable, allows for some air circulation, durable. | Not fully waterproof unless treated, heavier than synthetic options, requires regular maintenance. | Situations where ventilation is important, may not be ideal for consistently wet climates unless properly treated. |
| Vinyl | Highly durable, waterproof, UV resistant, long-lasting. | More expensive than other options, heavier, can be less flexible in cold temperatures. | Heavy-duty woodpile protection, harsh climates, long-term use. |
| Mesh Tarps | Allows for maximum air circulation, prevents moisture buildup. | Offers no protection from moisture. | Prevents moisture buildup on wood piles that are already protected from moisture, such as under a shed. |
IV. Tarp Features and Considerations
Beyond size and material, consider these additional features:
- Grommets: Ensure the tarp has reinforced grommets spaced evenly around the edges. High-quality grommets prevent tearing when securing the tarp with ropes or bungee cords. Consider the material of the grommets as well; rust-resistant options are preferred.
- Reinforced Edges: Look for tarps with reinforced edges to prevent fraying and tearing, especially in windy conditions.
- UV Resistance: If your woodpile is exposed to direct sunlight, choose a tarp with UV resistance to prevent it from degrading and cracking over time.
- Waterproof vs. Water-Resistant: Understand the difference. Waterproof tarps provide complete protection from water, while water-resistant tarps may allow some moisture to penetrate over time. For optimal woodpile protection, opt for a waterproof tarp.
- Color: While not directly impacting performance, consider the tarp’s color. Darker colors absorb more heat, potentially aiding in drying wood, but can also degrade faster in sunlight. Lighter colors reflect heat but may show dirt more easily.
- Weight: Consider the weight of the tarp, especially if you need to frequently move or adjust it. Canvas and vinyl tarps are generally heavier than polyethylene or polypropylene options.
- Security: Ensure that the tarp is secured well to minimize wind exposure. If you expect heavy storms, ensure to weigh down the tarp.
Frequently Asked Questions About Wood Pile Tarps
How much bigger should my wood pile tarp be than the wood pile?
Your wood pile tarp should be at least one foot larger than the wood pile on all sides. This ensures sufficient overhang to protect the wood from rain and snow. Extra length also provides options for securing the wood pile tarp.
What’s the best material for a wood pile tarp that will last for several seasons?
Heavy-duty polyethylene (poly) tarps or vinyl tarps are excellent choices. They are waterproof, UV resistant, and can withstand harsh weather. Investing in a thicker material will significantly extend the lifespan of your wood pile tarp.
Does the color of my wood pile tarp matter?
Darker colors like brown or green absorb more heat, potentially helping wood dry faster. However, any color will effectively protect your wood pile from moisture. Consider color based on aesthetics and sun exposure.
How do I properly secure a wood pile tarp to prevent it from blowing away?
Use bungee cords or rope to tightly secure the wood pile tarp to the wood pile itself or to stakes driven into the ground. Secure all edges and corners to prevent wind from getting underneath. Grommets should be reinforced to prevent tearing.
So, that’s the lowdown on choosing the right size and material for your wood pile tarp. Hopefully, you’re now feeling confident about protecting your firewood from the elements. A little planning and the right wood pile tarp can make a huge difference in how well your wood seasons and burns this winter. Happy chopping!
