You would think NASA would use this for space stations. Ever looked at Aerogel? That I have seen analyzed and also vacuum panels - they both work but have some inhibiting factors relative to use. Nansulate may have effective R Value of something but not a true R value - if it does show me a picture of the label claiming that; certainly that is on the package just like any insulation product. It is probably a roll on radiant barrier - like wrapping a potato in foil. It is effective at limiting the effect of infrared radiation but has virtually no R value - the laws of physics/thermodynamics are fairly absolute (except maybe the first law of TD - cause if it were true we shouldn't be here - unless the universe is a real illusion - the only thing that makes sense - it appears to exist - (for the first law to be valid the sum of the universe has to be zero) - just like Nansulate appears to insulate - no room for magic). I don't need to look further, if there was anything there you would have included it in your response.

Put in insulation and put it in correctly is my advice. If you put on two layers of Nansulate does it give you an R 38 (that is how it works with most insulation)?

Venting an attic or using sun shades or window films can save a lot of conditioning money too but that does not mean it insulates.

If this product hardens what happens if there's a electric or plumbing problem

It sets up - not necessarily hardens like structure foam - yes it is a pain to deal with - take pictures before covering things up so you have to do as little digging as possible. If you think you are going to (planning to) have to do work in the future put the elec in conduit. Pick your battles - better performance or easier repairs.
