I used 2, 4 X 8 sheets of foam insulation, covered them with batting and glued them to the sewing room wall with "No Nails". That was my mistake. To take them down and paint the room, they are up there too tight. I am having a Sewing Studio built in my DH's shop that will be very large and comfy, so the old wall will come down to return that room to a bedroom. Its going to be a lot of work to repair that wall. If your ceilings are 8 foot high, or 4 ft, you should be able to cover the insulation board and just push it gently into place.
