The “thermal blanket” search query gives more than 20,000 various models in online-shops; however, not all of them have all the required characteristics. Furthermore, in most cases, cheap fleece blankets are hidden behind the loud “thermal blanket” name. We have found and compared five real thermal blankets within the price range from $4 to $24. At the end of this article, you will also discover ten well-proven ways to use them.
How space blankets work
The thermal blanket is a unique and incredibly versatile product. An inevitable part of any rescue service emergency kit, it’s also called a “space blanket”, because NASA was using the very same tinfoil in the “Apollo” program. What’s the main feature of it? There are several of them: this blanket saves up to 90% of the human body warmth for a couple of days, it’s impermeable, water and dustproof, and it’s virtually impossible to tear it, while the price for one blanket is below $5. Such a combination of characteristics in a 50-gram package that can be used to cover an adult person with head makes this blanket mandatory stuff for any traveler, driver or just a practical person. It doesn’t require power sockets or accumulators, and it will keep you warm at any temperature! This blanket is really the warmest one of all the existing models.
By wrapping yourself in such blanket, you will keep the normal temperature of your body for a long time, keeping it warm in severe climatic conditions. If you decide to use it as a tent, you will protect yourself from the burning desert sun, because the material will reflect all the sunrays. The most important thing: never wrap yourself in the thermal blanket under the burning sun, because it may cause overheating. Such blankets should be used only as an awning in hot climatic conditions!
The TOP-5 of best survival blankets (emergency blankets, space blankets)
At first glance, one may think that all the thermal blankets are similar, because they are made from tinfoil. But don’t be so fast, because each model has its own purpose. Some blankets can be utilized instead of sleeping bags, while bigger single or multi-layer thermal blankets can be used not only to wrap someone around, but to create a fireplace in a swampy area or construct a shelter from them.

There are three best selling models among all the blankets in the budget segment. The first one is a Emergency Survival Mylar Sleeping Blanket – a set of two emergency sleeping blankets of 84 inches x 36 inches each.
This packaging is the most popular and requested one. Are you asking why? There are several factors: the price (the lowest one) and the fact that it’s a set for two people (the majority of customers simply doesn’t need a set of 10 blankets). The main disadvantage of this model that makes it worse than other blankets is hidden in the word, “sleeping”, because this blanket can’t be used for anything but sleeping due to its form of a sleeping bag. In other words, you can’t create various shelters using this sleeping bag. This model won’t take a lot of space, but it will definitely save you from the cold in an emergency situation. One should keep such a blanket in the car, in case you run out of fuel in a place with severe climatic conditions. You can spend a couple of days in such bag, paying no attention to the external factors. However, the tinfoil sleeping bag won’t save you from struggling or diseases, but it will definitely protect you from freezer burn. We recommend using this blanket in conjunction with a classic sleeping bag in case if you have one, but you don’t want to pay a lot of money for a specific isothermal one.

How to use emergency and space blanket
NASA's insulation technology has been widely used to create slim thermal blankets. Perhaps no one can appreciate these benefits more than victims of the earthquake that razed Pakistan, Afghanistan and India in October 2005. When relief poured into the region, aid included supplies of silver thermal blankets that doubled as ground covers during the day and blankets at night.
There are many different ways to use isothermal tinfoil. We have chosen the most practical and useful variants.
- Shelter to protect from the sun. The blanket is fixed above a specific area with a rope or any other means to keep revitalizing coolness above it.
- Reservoir for water. Due to its isothermal characteristics and relatively big size, the blanket can be used as a water reservoir. The material is waterproof, thus there’s no need to worry if you manage to fix your impromptu water deposit.
- Thermos for products. Do you want to keep your food fresh and safe? Just cover it with a thermal blanket that will keep it fresh for multiple days!
- Sleeping mat. If you are not worried about the wind and humidity, you can just use the thermal blanket as a warm mattress.
- Make a stretcher. If one member of your group hurt his or her leg, the best way to bring them back to a safe place is to use a stretcher. The thermal blanket is durable enough, thus it can be used to make a stretcher.
- Construct a shelter. Find a couple of branches and take a big thermal blanket to make a warm and dry shelter that will cover you from bad and dirty weather. You can find a full tent building guide on the website of the Oak Ridge National Laboratory
- Increase the campfire warmth. Create an isothermal tinfoil shield and stretch it behind the campfire, sitting on the opposite side. Such an approach will increase the level of warmth from the campfire and protect your campfire from wind.
- Campfire scaffold. Does it look impossible to create a campfire in a swampy area? Use a heated blanket and you can create it even in the middle of a lake! Don’t forget to fix it properly, and protect it from gusts of wind.
- Patches on clothes. If you tear a sleeve in a mountain region, you can put a cutout from an isothermal tinfoil blanket and forget about freezer burns.
- Create an emergency sign. Tinfoil becomes really shiny under the sun, thus you can use it to make a distress call, instead of using smoke signals.
