The thermal blankets were originally designed by NASA in the year 1964 for their US Space Program. However, the big companies soon became aware of the interesting benefits of this new technology and they started designing this type of blankets to serve the community.

These space blankets are made up of insulating material which is created by depositing vaporized aluminum on some thin plastic substrates. This flexible material helps to design a thin blanket with superior thermal properties. The aluminum coating further helps to deflect the harmful infrared rays while conserving the warmed inside.

In simple words, the material used for emergency or space blankets can help to bounce off heat or it can also preserve the existing heat. Hence, it is the best tool for maintaining the perfect temperature inside.

Picking up a space blanket for camping:

Well, you may find many different types of space blankets in the market from different brands; but in actual, all of them work in a similar manner. The main goal of these blankets is to prevent heat-loss while retaining almost 90% of the body heat. Note that they are not designed to create additional warmth.

Things to Know About Space Blankets


Space Blankets are best known for their outdoor uses. These are considered to be the most light weight and low bulk blankets.

Nowadays, space blankets are made in immense quantities because of their increased demands. However, the first space blanket was created in 1970 and was first used by the Skylab space station. They used this blanket to protect themselves from overheating while their spacecraft was orbiting the earth. 

When the Skylab space station was orbiting the earth, their heat shield broke due to some accident; thus, their inner atmosphere was starting to become warm. NASA became worried as there was a chance that the equipment present in the station can get damaged. Therefore, they decided to use these aluminum wrapped blankets to protect themselves and their equipments.


Working of a Space Blanket

A space blanket is made by mixing a fragile aluminum sheet with a plastic film. These sheets are made adaptable, lightweight, and reflective.
