Getting ready to insulate the ceiling. I have one super sensitive neighbor and everyone else says they don't hear anything in their house or it's very faint outside. I have two little kids, so the only regular time I get in the shop is after 8 once I get them into bed and finish chores. My plan was to put fiberglass in the ceiling (with an airgap), cover with eps and plywood. In another thread I saw that acoustical tiles work well so I'd be up for putting those in as well. I dunno... I do want to be respectful of the neighbors but I'd never have anytime to WW if I don't do it late. I thought we moved into unincorporated township expressly for this kind of reason. Is there that much of a difference between rockwool and fiberglass for sound? Any other tips are appreciated.
