I'm going off the test data done by various laboratories that do R value testing and research. I'm sure you've read the same stuff.

What might be more interesting is foil bubble wrap testing, although i'm not sure you could measure the actual results with an infrared gun as it would provide more benefit than measured off just the backside.
Horizontal heat reflectiveness isn't near that of the vertical.

The Rvalue testing measures the change in the environments on each side of the insulator, not the backside temp change. The back side temp is useful in window testing for feel it provides when you are next to it as the difference is dramatic.

Where's the data?
