"Roxul safe and sound" or original foam insulation?

[guruqu]

Hi:

We are trying to decide whether to replace our current foam insulation. (Something like in the picture).
Some one mentioned that Roxul Safe and Sound product is a better choice in terms of sound dampening.


Thanks!

Yes,
Cotton fiber insulation, mineral wool or Roxul will perform better than this foam insulation.
dont forget the rest of the rules...
mass, mass, mass you need to double the weight for good results.
seal, seal...seal everything like a fish tank including any outlets...sound will act like water.
and if your dealing with any impact or bass you must use clips and channel.
