I see that putting up dry wall and then put a layer of quiet film in-between or use green glue between 2 layers of dry wall?
Can I put quiet film on the existing wall without adding dry wall and paint over it in white- would that be enough of a sound barrier, and would that look good?
What other options do you have? keep in mind wall is in the dining room, and I have a nice mirror hanging on the wall, and the wall that is next to it is a window looking out to my patio I have about 2 inches from the wall to the widow frame . (I do not want to hang curtains, or eggshell foam)
