[QUOTE="keep_hope_alive, post: 7639583, member: 576029"] the stuff i used was actually salvaged from some pillowtop cushions i had - so the actual makeup/source is not known. it was a fairly dense sheet that was sewed on the ends. in the future, pvc encased fiberglass will be what i use. i wouldn't say it provides "sound damping" but sound absorption. water causes "dampening" - common misuse of the term. absorption comes from causing air molecules to generate friction or rapid increase/decrease in speed as it works through smaller openings. energy is lost in the process. even polyfill provides some absorption, though much less than fiberglass.
