Rockwool "safe n sound" acoustic insulation. Ran out of itch tolerance, still need to finish the spare bedroom and the kitchen tomorrow but I have to get some retainer wires, the kitchen joists are 16”(ish) on center and the insulation won't stay up with just friction because the spacing is too wide by like half an inch. Grrr.
Trying to cut the noise from the upstairs apartment into the downstairs apartment in my duplex. Didn't
want to spend the $1700.00....but now's the time while the drywall is out, and it really DOES make a difference. Before, it sounded like the neighbors were
in the room with me. Now, I can still hear heavy footsteps (material transmission - when the floor moves you still hear it), but talking, yelling/crying children, all that stuff...gone. Very pleased. The only wall I did is the wall for the entry stairs for upstairs - it's a bedroom so I wanted to do as much as I could. Again, while the drywall is out.
Only debate is...do I double up in the bedroom ceiling? I overbought (I can return unused) so I'll have more. It's designed for 2x4; floor (ceiling) joists are 2X8 so there's room...can't decide if the airspace and relaxed nature would work better, or if dense-packed would be better. The master bedroom is under the kitchen for upstairs. Kitchen has tile flooring so quieter already...I dunno. I'll see how much I have left.
And how sick I am of itching.
