Quick Answer
For winter tarp usage, larger and more rectangular tarps are recommended to accommodate snow loads and increased wind resistance, while smaller tarps may not provide sufficient protection.
Choosing the Right Tarp Size for Winter
When it comes to using a tarp in the winter, size is crucial for withstanding snow loads and strong winds. A larger tarp (at least 10x13 feet) is recommended as it provides more surface area to shed snow and distribute the weight more evenly. This size also helps to reduce the risk of collapse due to snow accumulation.
Snow Load Considerations
When dealing with snow, the weight of the load is critical. A general rule of thumb is to calculate the snow load in pounds per square foot. For example, if you’re expecting 2 feet of snow, the load would be approximately 20 pounds per square foot. A 10x13 foot tarp would need to support around 260 pounds of snow, which is equivalent to about 2 feet of snow at a density of 10 pounds per cubic foot.
Tarp Shape and Orientation
A rectangular tarp is more effective in the winter than a square or round one due to its ability to shed snow more easily. For optimal performance, orient the tarp with the longer axis parallel to the wind direction to minimize the impact of snow accumulation. This will also help to reduce the risk of the tarp collapsing or becoming damaged. Additionally, ensure the tarp is securely anchored with sturdy stakes or rope to prevent it from being blown away or damaged by strong winds.
