It's Reflectix by another name. It has an actual R-Value of 1.
Applying my critical thinking head, just for a moment, I wonder why, if this lives up to its claims, everyone isn't using it.
It's about a 1/4" thick and claiming double 1" of sprayfoam.
I do wish they could be made to be just a bit more honest, and that's no reflection(sic) on anyone who might wonder if this stuff works.
It does work, kinda, sorta, maybe, on insulation schemes that include real insulation, and large air-gaps.
