Some people use polyfill, like what's used as batting in pillows and winter coats. I find it to be awkward to use, because it doesn't hold together well. "Acousti-stuff" is a branded polyfill, packaged and sold by Parts Express. Ultratouch is a cotton product replacement for R13 that you might try.
