I got both side walls insulated and started the on first layer of drywall.
Tonight i finished taping and mudding one wall
Tomorrow after its dry i will start on the second layer on the parti. wall !
In this pic. you can see the acoustical caulking on the bottom of the sheetrock,
Every layer gets a 1/4 " gap and acoustical caulk around all the edges. And the seams get taped .. all to make each layer air tight and so the edges of the drywall wont transmit vibrations to the other wall or ceiling, floor, ect...
(to increase transmission loss)
