so, left and right sides of garage have cinder blocks so maybe 4 inches of space (filled with woolly stuff?) 2 staggard layers of sheetrock - 2x4 studs (with insulation/wooly stuff inbetween the studs - covered by some kind of cloth?
the wall facing the front/garage door side? should i attach a layer of insulation onto the inside of the garage door? come up with some way of sealing around the garage door? then 2 layers of staggard sheetrock - 2x4 studs - insulation and cloth to hold it in?
or should the wall facing the garage door have the staggard 2 walls with staggard 2x4 studs and sheetrock on the outsides of each stud wall? and insulation inbetween the stud walls?
i hope this is clear enough... argh... then of course there is the acustic treatment inside the room!
