Quick Answer
Silnylon, Dyneema, and silicone-coated polyester tarps are ideal for wind resistance due to their high tear strength and durability, while silicone-coated nylon and Tyvek tarps are also good options.
Tarp Material Characteristics
When it comes to wind resistance, the material of your tarp is crucial. Look for materials with high tear strength, which is typically measured in Newtons per square millimeter (N/mm²). Silnylon, for example, has a tear strength of around 35-40 N/mm², making it an excellent choice for windy conditions. Dyneema, on the other hand, has an even higher tear strength of up to 50 N/mm², making it nearly indestructible.
Tarp Coatings and Finishes
In addition to material selection, a tarp’s coating or finish can also play a significant role in wind resistance. Silicone-coated polyester and nylon tarps, for instance, have a water-repellent coating that prevents wind-driven rain from penetrating the fabric. This is especially important in high-wind situations where water can easily seep in through the fabric. When choosing a coated tarp, look for a silicone coating with a thickness of at least 0.5-1.0 mils (13-25 microns) for optimal performance.
Tarp Pitch and Anchoring Techniques
The way you pitch and anchor your tarp can also affect its wind resistance. When setting up your tarp, aim to pitch it at an angle of around 30-40 degrees to maximize its wind-resistance. Additionally, use multiple anchoring points, such as stakes and trees, to secure the tarp tightly to the ground. When using stakes, drive them into the ground at a 45-degree angle to prevent them from being ripped out by strong winds.
