When selecting a tarpaulin, commonly known as a tarp, one of the most critical factors to consider is its thickness. The thickness determines not only the durability and strength of the tarp but also its suitability for various applications. Whether you're protecting construction materials, covering outdoor equipment, or setting up a temporary shelter, understanding tarp thickness is essential. This comprehensive guide delves into the intricacies of tarp thickness, helping you make an informed decision tailored to your specific needs.
For those involved in building projects, choosing the right tarp is paramount. Utilizing construction tarps with appropriate thickness ensures materials and equipment are well-protected against the elements.
Tarp thickness impacts several key aspects, including durability, weight, and flexibility. A thicker tarp generally offers enhanced strength and resistance to tears, punctures, and abrasions. However, thicker doesn't always mean better—it depends on the intended use. Too thick, and the tarp may become unwieldy; too thin, and it might not provide adequate protection. Therefore, understanding how thickness is measured and what it means for different applications is crucial.
Tarp thickness is commonly measured in mils and ounces per square yard. Understanding these units helps in comparing different tarps and selecting the right one for your needs.
The term "mil" refers to one-thousandth of an inch (0.001 inches). It's a standard unit of measurement in the tarp industry to indicate thickness. For example, a 10 mil tarp is 0.010 inches thick. This measurement gives a precise indication of the tarp's thickness, which correlates to its durability and protective qualities.
Alternatively, tarp thickness can also be expressed in ounces per square yard (oz/sq yd). This measurement indicates the weight of the tarp material over a standardized area, giving insight into its density and sturdiness. For instance, a tarp listed as 18 oz/sq yd is heavier and typically more robust than one that's 10 oz/sq yd.
Understanding how mil thickness and ounce weight correlate can be instrumental in choosing the right tarp. Here's a simplified tarp thickness chart to illustrate common thicknesses and their typical uses:
| Thickness (Mil) | Weight (Oz/Sq Yd) | Common Uses |
|---|---|---|
| 5-6 Mil | 2-3 Oz | Light-duty covers, short-term use |
| 10 Mil | 5-6 Oz | General-purpose tarps, camping |
| 16 Mil | 10 Oz | Heavy-duty applications, construction |
| 20 Mil | 13-18 Oz | Industrial use, long-term outdoor exposure |
| 50 Mil | 40-50 Oz | Extreme heavy-duty, specialized applications |
This chart provides a general guideline, but actual weights and thicknesses may vary depending on the tarp material and manufacturer.
Several factors should be considered when determining the ideal tarp thickness for your needs. These include the intended application, environmental conditions, and the desired durability and longevity.
The purpose for which you need a tarp greatly influences the appropriate thickness. For light-duty tasks like covering patio furniture or providing temporary shelter during camping, a 5-10 mil tarp may suffice. However, for heavy-duty applications such as covering machinery, vehicles, or serving as a roof cover, a thicker tarp—ranging from 16 mils upwards—is recommended.
Consider the environmental elements the tarp will face. In regions with extreme weather—strong winds, heavy snowfall, intense UV exposure—a thicker, more robust tarp offers better resistance. Thicker tarps are also less likely to tear or degrade under harsh conditions, ensuring that your protected items remain safe.
If the tarp is intended for long-term use, investing in a thicker option is prudent. Thicker tarps, such as 20 mil or even 50 mil options, provide enhanced durability, resisting wear and tear over extended periods. This is especially important for applications where replacing the tarp frequently is impractical or costly.
When deciding between a 10 mil and a 16 mil tarp, it's essential to weigh the specifics of your application.
10 Mil Tarps: These are versatile and suitable for general-purpose use. They're lighter, more flexible, and easier to handle, making them ideal for temporary covers, camping, or protection against mild weather conditions.
16 Mil Tarps: These tarps are significantly thicker and offer superior durability. They're better suited for heavy-duty applications, including construction sites, long-term outdoor storage, and protection against severe weather.
In essence, if you require a tarp for rigorous use and extended exposure to harsh conditions, opting for the thicker 16 mil tarp is advisable.
When it comes to tarps, thickness can vary significantly. The thickest tarps available in the market are around 50 mils thick. These ultra-heavy-duty tarps are designed for specialized applications that demand maximum durability and resistance.
A 50 mil tarp offers exceptional strength and is often used in industrial settings, such as covering large machinery, constructing temporary shelters in disaster zones, or even as liners for ponds and landfills. Due to their substantial weight and rigidity, they are less portable and more challenging to handle, but they provide unparalleled protection and longevity.
Different tarp materials affect both the thickness and the performance of the tarp. Common materials include polyethylene, canvas, and vinyl, each with unique properties.
Polyethylene tarps, or poly tarps, are made from woven polyethylene fabric with a plastic coating. They are lightweight, waterproof, and affordable, making them popular for various uses. Thickness ranges from light-duty 5 mils to heavy-duty 20 mils. Poly tarps are suitable for temporary covers, camping, and protecting items from moisture.
Canvas tarps are crafted from cotton or polyester. They're breathable, making them ideal for covering items that need air circulation, like machinery or hay. Typically heavier and thicker (ranging from 16 oz to 30 oz per square yard), canvas tarps are durable but not entirely waterproof unless treated.
Vinyl tarps are known for their high durability and resistance to tearing. They are heavier, with thicknesses ranging from 10 mils to over 50 mils. Vinyl tarps are waterproof, resist mildew, and are excellent for industrial applications, trucking, and long-term outdoor exposure.
Choosing the right tarp thickness ensures optimal performance for specific applications. Here's how different thicknesses align with common uses:
5-6 Mil Tarps: Ideal for short-term, light-duty coverage like protecting furniture during painting or covering firewood temporarily.
7-10 Mil Tarps: Suitable for camping, covering vehicles, and general-purpose use where moderate durability is acceptable.
12-16 Mil Tarps: Great for construction sites, medium-term outdoor storage, and agricultural uses where enhanced strength is required.
20 Mil Tarps: Designed for heavy-duty applications, including industrial equipment coverage, long-term storage, and exposure to severe weather conditions.
30-50 Mil Tarps: Used in extreme conditions and specialized industries. They provide maximum protection for large-scale projects, environmental containment, and heavy machinery.
Understanding the specifications provided by manufacturers can sometimes be confusing. Here's how to interpret common terms:
Mil Thickness: Indicates the tarp's thickness in thousandths of an inch. Higher mil numbers mean thicker tarps.
Oz/Sq Yd: Refers to the weight per square yard. Heavier weights generally correlate with increased durability.
Weave Count: The number of threads per square inch in the tarp's fabric. A higher weave count usually means a stronger tarp.
When comparing tarps, consider all these factors collectively rather than focusing on a single specification.
So, how do you decide between a 10 mil tarp and a 16 mil tarp? Let's break down the considerations:
A 10 mil tarp is lighter and more portable, making it easier to handle and transport. It's suitable for tasks that require frequent setup and takedown. In contrast, a 16 mil tarp is heavier and less portable but offers superior durability and resistance to harsh conditions.
Thicker tarps generally cost more due to the additional material and enhanced manufacturing processes. If budget constraints are a factor, consider whether the added durability of a thicker tarp justifies the higher expense.
Match the tarp to the demands of your application. For example, a 10 mil tarp may be adequate for covering a boat during the off-season, while a 16 mil tarp might be necessary for protecting construction equipment exposed to the elements year-round.
Regardless of the tarp thickness you choose, proper care can extend its lifespan. Here are some practical tips:
