Keep looking for perlite or vermiculite - both are used for gardening. Wal mart has them. (Ashes mite work, not sure what u r making.)
Fiberglass is cheap and fireproof, but will lose insul value after dirt/suet gets in it. Also it gets brittle and changes composition after a year of exposure to heat. Works great for about a year though.
