Quick Answer
Thermal blankets are effective for additional warmth in shelters when used correctly, particularly in extremely cold conditions such as ice fishing. They can help retain body heat and prevent heat loss through radiation and conduction.
Using Thermal Blankets in Cold Shelters
When choosing a thermal blanket, look for one that is rated for extreme cold and has a high fill power rating, such as the US Military’s ALR-AN or the ALPS Mountaineering Bivy Sack. These blankets are designed to retain heat in cold environments and can be used in conjunction with a sleeping bag or other insulation to increase overall warmth. A thermal blanket with a fill power rating of 3-4 inches can maintain heat in temperatures as low as -20°F (-29°C).
Setting Up a Thermal Blanket in an Ice Fishing Shelter
To set up a thermal blanket in an ice fishing shelter, start by laying it out on the floor of the shelter and securing it with stakes or weights to prevent it from shifting. This will help to trap warm air and prevent cold air from entering the shelter. Next, place a sleeping bag or other insulation on top of the thermal blanket, followed by a warm layer of clothing or a sleeping pad. This setup can help to maintain a comfortable interior temperature in extremely cold conditions.
Additional Tips for Using Thermal Blankets in Cold Shelters
When using a thermal blanket in a cold shelter, it’s also important to consider factors such as ventilation and moisture. Make sure to provide adequate ventilation to prevent the buildup of carbon dioxide and moisture, which can quickly lower body temperature. Additionally, avoid getting the thermal blanket wet, as this can significantly reduce its insulating properties. By following these tips and using a high-quality thermal blanket, you can stay warm and safe in even the coldest conditions.
