Hi, I live is a side by side Condo complex that doesn't have good sound
insulation between units. Is there any way to achieve around a 55-60
STC for the vertical walls between my unit and the other two without
having to replace the drywall with something like the QuietRock system?
I looked at Fomo Foam but can't find any reviews of it and what kind
of STC it would provide me. Thanks, Danno
