Quick Answer
For temperature regulation in shelters, the best tarp choices are those with a waterproof and breathable membrane, such as silnylon or nylon ripstop, and a waterproof coating. Look for tarps with a high denier rating, such as 1.9 oz or 2.5 oz. This will ensure a good balance between durability and weight.
Choosing the Right Tarp Fabric
When selecting a tarp for temperature regulation, the fabric is a critical component. Look for tarps made from waterproof and breathable materials such as silnylon or nylon ripstop. These fabrics will allow moisture to escape while keeping rain and snow out. A high denier rating, such as 1.9 oz or 2.5 oz, will ensure the tarp is durable and resistant to tears.
Tarp Configuration and Pitch
The way you pitch your tarp can greatly affect temperature regulation. A diamond configuration is ideal for rain and snow, as it allows for a steep pitch and excellent water runoff. To create a diamond configuration, use a ridge line and two side lines, and make sure to tie the tarp off at a high point to maximize the slope. A plow point or lean-to configuration is better suited for high winds, as it provides additional stability and protection.
Knots and Attachment Points
When setting up your tarp, the knots and attachment points you use are crucial for ensuring a secure and comfortable pitch. Use a trucker’s hitch or a rolling hitch to secure the tarp to trees or poles, and make sure to tie the ridge line off at a high point to maintain the desired pitch. Use a bowline or a figure eight to attach the tarp to a fixed point, such as a tree or a rock.
