When it comes to protecting your equipment, goods, or property from the elements, few materials are as versatile and reliable as tarpaulins. Whether you’re looking to cover construction equipment, protect crops, or create a temporary shelter for an outdoor adventure, choosing the right tarpaulin is essential. With so many options available in terms of material, size, and features, it can be overwhelming to determine which one best suits your specific needs.
In this comprehensive guide, we will walk you through everything you need to know about choosing the right tarpaulin. From understanding different types of tarps to evaluating key factors like material, durability, and weather resistance, we’ll help you make an informed decision that ensures your tarp works as effectively as possible.
What is a Tarpaulin?
Before diving into the specifics of choosing the right tarpaulin, it’s important to understand what a tarpaulin is and why it’s such a useful material. A tarpaulin (often shortened to “tarp”) is a large sheet of strong, flexible material that is typically waterproof, weather-resistant, and durable. Tarps are used to cover, protect, or store items, often in outdoor environments where exposure to the elements can cause damage.
Tarpaulins are most commonly made from materials like polyethylene, PVC (polyvinyl chloride), and canvas. These materials vary in terms of strength, weight, and resistance to water, UV rays, and other environmental factors.
Now, let’s explore the main factors you should consider when choosing the right tarpaulin for your needs.
1. Types of Tarpaulin Materials
The first step in selecting the right tarpaulin is understanding the different materials available. Each material has its own set of advantages and is suited for specific uses. Below are the most common materials used in tarpaulins:
Polyethylene (PE) Tarpaulins
Polyethylene tarps are lightweight, affordable, and highly versatile. They are typically made of woven fabric coated with a layer of polyethylene, which makes them both waterproof and resistant to UV rays. PE tarps are ideal for general-purpose use, such as covering outdoor furniture, boats, or building materials.
Advantages of PE Tarpaulins:
- Lightweight and easy to handle.
- Waterproof and UV-resistant.
- Affordable and available in a variety of colors and sizes.
- Resistant to mildew and rot.
Best for: Short-term use, temporary covers, and light-duty applications.
PVC (Polyvinyl Chloride) Tarpaulins
PVC tarps are heavier and more durable than polyethylene tarps. Made from a tough plastic material, these tarps are excellent for heavy-duty applications. They offer superior resistance to chemicals, abrasions, and extreme temperatures, making them ideal for industrial, agricultural, and marine environments.
Advantages of PVC Tarpaulins:
- Extremely durable and long-lasting.
- Resistant to chemicals, UV rays, and harsh weather conditions.
- Offers high tensile strength, making it suitable for heavy-duty applications.
Best for: Heavy-duty industrial use, construction sites, and marine applications.
Canvas Tarpaulins
Canvas tarps are made from cotton or polyester fabrics, making them more breathable than polyethylene and PVC. While they are not as waterproof as plastic tarps, they are highly durable and provide excellent protection from sunlight, rain, and wind. Canvas tarps are often used for applications where breathability is needed, such as covering hay bales or providing shelter in farming.
Advantages of Canvas Tarpaulins:
- Durable and breathable.
- Good resistance to sunlight, rain, and wind.
- Environmentally friendly (biodegradable).
- Comfortable for applications like temporary shelters.
Best for: Long-term outdoor storage, agriculture, and camping.
2. Size and Dimensions
One of the most important factors to consider when choosing a tarpaulin is size. Tarps come in a variety of sizes, and selecting the right one depends on the area you need to cover or protect. The first thing to do is measure the area that requires coverage, keeping in mind that you’ll want to have some extra material for securing the tarp in place.
Key Considerations for Size:
- Length and Width: Measure the length and width of the surface you wish to cover. Make sure the tarp extends slightly beyond the edges of the area to ensure full protection.
- Overhang: Consider adding 2 to 3 feet of overhang around the perimeter of the object you are covering. This will help provide additional coverage and allow for securing the tarp in place.
- Shape of Area: If you’re covering a flat surface, rectangular tarps will usually suffice. However, if you’re covering a structure like a tent or vehicle, you might need a more custom shape or multiple tarps.
Most tarps come in standard sizes, but custom sizes are also available. If you have specific needs, such as covering an oddly shaped area, you might need to explore options that allow you to order tarps in your preferred dimensions.
3. Strength and Durability
The durability of your tarpaulin depends on both the material used and its weight. Tarps are typically rated by their weight, with heavier tarps offering more strength and longevity. If you are using the tarp for heavy-duty applications or in harsh environments, a more durable and stronger tarp is essential.
Lightweight Tarpaulins:
- Typically around 3-5 oz per square yard.
- Ideal for general purposes like covering lawn furniture, outdoor gear, or light storage.
- Suitable for short-term or seasonal use.
Medium-Duty Tarpaulins:
- Typically around 6-10 oz per square yard.
- Good for construction, agriculture, or outdoor camping.
- Offers better durability and resistance to wear and tear.
Heavy-Duty Tarpaulins:
- Typically over 10 oz per square yard.
- Ideal for industrial, marine, and commercial applications.
- Provides superior strength and long-lasting durability under extreme conditions.
4. Weather Resistance: UV Protection and Waterproofing
When choosing a tarpaulin, it’s crucial to consider the weather conditions it will be exposed to. The ability of the tarp to resist UV rays, water, and extreme temperatures will affect its lifespan and functionality.
UV Protection:
If you plan to use your tarpaulin in a sunny area, UV protection is essential. Tarps that are UV-resistant will not break down under direct sunlight, meaning they will last longer and remain effective even after prolonged exposure to the sun.
Polyethylene and PVC tarps are often treated with UV inhibitors to extend their lifespan in sunny climates. If you’re using a tarp for long-term outdoor storage or over a vehicle, be sure to choose a UV-resistant option.
Waterproofing:
Most tarpaulins are water-resistant, but some materials, like canvas, may allow water to seep through if exposed to heavy rainfall for long periods. If your tarp needs to provide reliable waterproofing, ensure that the material is coated or treated for water resistance. PVC and polyethylene tarps are highly waterproof, making them suitable for covering goods or creating shelters during wet weather.
5. Reinforcements and Grommets
Reinforced edges and grommets (metal rings) are crucial features in ensuring that your tarpaulin stays securely in place. These features help increase the tarp’s strength, especially in windy or stormy conditions.
Reinforced Edges:
Look for tarps with reinforced edges or hems, as these will help prevent tearing and ensure that the tarp holds up under tension. Reinforced edges also allow you to secure the tarp more effectively by tying it down.
Grommets:
Grommets are used to attach ropes or bungee cords to the tarp to keep it in place. Tarps with grommets around the edges make it easier to secure them to a frame, vehicle, or structure. The more grommets there are, the more flexibility you’ll have when tying the tarp down.
For heavy-duty applications, look for tarps with brass or stainless steel grommets, as these are more durable and rust-resistant than standard metal grommets.
6. Cost Considerations
Tarpaulins vary significantly in price depending on their material, size, and features. While it can be tempting to go for the cheapest option, consider the long-term costs associated with purchasing a lower-quality tarp that may wear out quickly or fail to protect your items properly.
Investing in a high-quality tarp will pay off in the long run, especially if you need it for heavy-duty or long-term use. Keep in mind that a more expensive tarp may offer better durability, UV protection, and water resistance, which could save you money on repairs or replacements in the future.
