Does this stuff work any better than R-30 Unfaced pink insulation?

Looking at putting some more insulation over blown insulation in my attic in an effort to reduce sound somewhat.

It won't work any better than fiberglass.  You'll pay a lot more for the hype, of course...

You can get a 40 sq. ft. roll of R-13 fiberglass for about 9 bucks.  And you can pick it up at your local home center - no waiting.  Stick with the simple solution..

Thanks.  I can get Pro Pink R-30 unfaced insulation at Home Depot for $9.37 a roll..but do you really think it would even provide any additional sound insulation in the attic if I put it over the existing blown insulation.

It would help.  It would also help your energy bills.

What noise are you trying to block, specifically?
