There are emergency blankets of all sorts – from one-use-only, to blankets that won’t tear no matter what. Even though they are very thin, some emergency blankets can be very durable and can be used to build a tent, using a string and some sticks.

Thanks to their quality of reflecting heat, this shelter will be a warm one. One good example is using an emergency blanket to cool off your car during very hot days. When your car gets overheated, you can stretch the space blanket on the windscreen of your car with the glossy part outside and you can protect your car from extreme temperatures.

Wind Resistance and Light Reflecting

At the same time, another feature that makes these blankets very useful is their wind resistance and waterproofing. When they are used as a shelter, camping blankets are an excellent way to protect you from the rain and the wind.

Because they reflect very well the sunlight, space blankets can be seen from great distances.

Weight and Size

Also, their low weight is a feature that many people appreciate. The fact that they are lightweight helps you to transport them easily. For instance, when going on a camping trip, you can pack several of these blankets without even feeling the extra weight.

Generally, camping blankets are large enough to cover an adult person in the case of an emergency. In addition, their length and width are reasonable in lots of other situations like: protecting walls or windows, building a shelter, protecting the body from moisture and coldness of the ground and more.


As you can see, there are plenty of uses for camping blankets. At the same time, they are used in various fields with plenty of goals. For example, marathon runners use them at the finish line to adjust their body temperature – when they stop, their temperature drops suddenly.
