Not very good, for either sound or heat/cold. That's why newer houses have insulation in all external walls and all attics should have some kind of insulation in them.
Before we remodeled out house, we didn't have insulation in the walls. On a southwest facing exposure, the sun was setting one day and I felt the inside wall (drywall) and it was about 90 degrees. The heat was just radiating through the stucco and through the drywall.
Also, without insulation in the walls, sound comes through very easily. Without the insulation, the sound waves cause the sheet of drywall to vibrate and it will radiate sound.

not very good. it is more of a type of conductor than anything. fiberglass or rigid foam would be a much better choice
