It is particularly useful for comparing transparent barriers such as glass. As the article states however, it is hard to measure. | |

| Oct 30, 2015 at 13:56 | comment | added | hazzey♦ | I think that @ChrisMueller's link to Wikipedia explains some of the background confusion. The problem is that different insulating works in different ways, but we only ever talk about "R". Maybe the real question is how to define amount of insulation between different types? | |
