[Greenbuilding] Nansulate Insulation

[elitalking]

Does anyone have experience with Nansulate.  I have been asked about it.  I looked at their web site.  This thin coat application is claimed to be insulation.  However, they do not provide R value of insulation.  They are claiming a 33% reduction in heat flow after 3 coat application.  It seems to me that the most significant potential might be as an air barrier reducing infiltration.  However, they are claiming significantly reduced conductance.  It is hard to believe that such a thin layer could have a significant impact on conduction.  In Youtube video of link below, they show reduced thermal bridging with before and after thermal image.

Is this stuff legitamate or snake oil?
