Has anyone tried Roxul Safe N Sound (or similar) for soundproofing?
I wanted to use Green Glue and double drywall between my floor trusses to add mass and reduce sound transmission between floors. But 24 cases of Green Glue is fairly pricey even before installation labor.
One insulation contractor has proposed netting in 5.5 inches of BIB insulation, but I’m not confident this approach will do much to muffle traffic on wood floors. One builder I know suggested using rockwool (Roxul or similar) because it is fairly dense and easy to install. What does the Green Building community think? I know what I would do with an unlimited budget, but I think an affordable approach that will reduce footfalls and such.
