I've only used Insul-Bright with cotton batting and haven't found it to be noisy. I've also used several layers of cotton batting and I think that does just as well. I would question using the Bosal's In R Form in potholders. The instructions for it say that it can be tumble dried with no heat, or air dried. I'm not familiar with the product, but I can't find anything saying it would be suitable for potholders. It contains foam and tricot, but I haven't out what either is actually made of.
