Thats an R value of 44 per inch. If it were true wouldn't all us home builders have been using it for years? Does this sound too good to be true? I'll pass, thanks
I multiplied the lowest given R rating (8.1) by the inverse of the thickness (3/16) to find the R value of an inch (=43.2)Where does the 44 come from?
I went right on http://www.carinsulation.com and bought a 30ft roll, worked out awesome. I haul a lot of cold food around in the back of my van and this helped out a lot.Thanks to everyone for the input...always open to hear more ideas! Seems there is no one right answer..
