Has anybody tried this material to see if this makes a good dampening material for speaker cabinet?
http://www.bondedlogic.com/ultratouch.htm
here are the NRC values
Size Thickness 125 250 500 1000 2000 4000
R-13 3.5” .95 1.30 1.19 1.08 1.02 1.00
It seems to be better than whispermat on NRC figures.
Feedbacks and comparison with other materials are appreciated.

I've been using it for damping in my U-baffle setup. Very nice. Nicest damping material I've found in my 35 years of messing around with speakers.
The only down side is a small amount of the boron based fire retardent that they use for critter, mold, and fire control will sift out of the cotton. This is a temporary condition and stops after a few weeks.

It only shows up as a fine white powder on the bottom surfaces of the baffles. Not really a problem. Cleans up easily with a vacuum cleaner with fuzzy brush attachment.
After a couple of vigorous exersize sessions playing pipe organ music at insane levels no more powder is coming out of the damping...
