"Hi, I'm in Delaware."
My mom was redoing some of her basement and bought a bunch of Owens Corning Foamular 250 to put between the laundry room and the TV room to keep some of the sound out. It helps, but obviously it is not the same as the 700 stuff. However, there's a bunch of it left over that I can have, so I'm wondering how it actually compares to 700. I couldn't find any data online, so I was hoping someone here might know. I guess I could always e-mail Owens Corning if I can't find it any other way...

It's 1" thick and has an r-value of 5, though I know that is for heat and not sound.
 
It looks to be the ridge foam board -similar to styrofoam board?. Likely it's too hard and reflective for absorbing duties- but I glommed on to a 5x5' sheet of 3/4 'map board (brought home from wifie's old day gig' :) ) that with soft added over it is doing nice handy 'lean around lite (read easy-mobile) baffling around here. ('First call is knocking down PC noise -not isolation but quite a lot actually.. or just helping out with inst/amp cubbies, that sort of thing.
