Delta T insulating coatings?

Has anyone had any experience using the DeltaT insulating coatings? As long as I am replacing the entire headliner in my boat (other Bahama 30 owners know that they are huge) I wanted to insulate it with a closed cell foam which has its ups and downs (toxic when burned) (won't absorb moisture). The company rep that I spoke with said when painted on at 40mils it will have an R value of like R12-R14. I am no expert on insulating but he said it would be a good vapor barrier. It has super duper small ceramic bb's that are hollow and act as a great insulator. He also told me that he was going to paint it on the inside of his Catalina 30 but never got it done before he sold it. Its costs 55bucks a gallon and cover 25 sq ft at the recommended thickness of 40 mils per gallon. Could get quite expensive when all said and done. I plan on using a wall mounted diesel heater as well as a forced air unit to keep me dry and warm here in the Inland northwest this winter. Any suggestions would be greatly appreciated

40 mils and R-14, I doubt. Vacuum pannels offer high Rs, gas filled pannels in close cells offer R-9 if punctured, and we have 1" thick ! These are refrigeration figures and I have no idea about boat insulation. Islander, get out and move down here

I seriously doubt a 40 mils thick coating can have an R-value of 12-14. Insulation generally requires volume. At $55 a gallon, it sounds like snake oil... but that's just me.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
