What is R-Value?

Various industries use R-Value to measure an object’s thermal resistance. Objects that resist heat more effectively receive a higher R-Value, such as sleeping mats, like we’re talking about today, to windows. 

Right, that’s the technical answer; albeit shortened massively, but how does this relate to sleeping mats? 

Understanding R-Value: How Sleeping Mats are Tested and Rated for Camping Comfort

A cold chamber sandwiches sleeping mats between two metal plates with an electrical current to test them. The sensor requires less electricity to achieve its desired temperature if the sleeping mat has plenty of insulation. However, if the mat has almost no insulation, the heat from the plates will escape, requiring more power and taking longer. Scientists use various technical terms to determine the R-Value of a sleeping mat, which indicates its level of insulation. This value is simplified for easy understanding. Check out the diagram provided by by Therm-A-Rest that gives you a good idea of which rating you’ll need for the time of year you’ll be camping.
