It sounds like some pro's recommend using poly caulk for airtight drywall installation. My question is could I used the acoustical caulk instead and achieve same results as poly caulk? At the end of the day, I was hoping to kill two birds with one stone and achieve some level of soundproofing and good "thermal" barrier/no air draft.
