Here for the gear
 

I've been trying to find any density and acoustic information on this product. It seems like they're working really hard not to provide this information... I did find this:

Thermafiber NRC & STC Data (this seems to generic Thermafiber info based upon product density; i.e. if our product is X thick, this is the NRC):

Walls and Ceilings (your go-to source for all wall and ceiling news...) wrote an article stating UltraBatt has an STC of 30:

I have a feeling this stuff is exactly the same as SAFB but repackaged / branded to compete in a different (cheaper) market / application. I'm debating on taking a chance on it. It's so much cheaper and easier to get ahold of. I wish someone smarter than me could chime in and let us know if it's any good.
