Look at Owens Corning' OWN data.

I have detailed the limitations of that data in great detail in my Density Report here:
Rigid fiberglass density tests
Joel, read it more than once if necessary. Especially the part about the problems with third octave averaging and not measuring or reporting what happens below 100 Hz. Also, I suggest you buy the ASTM C423 spec which explains that standard test labs are unreliable even at 125 Hz, and can be off by 50 percent.
