Fiberglass insulation is used as lining in sheet metal square duct to prevent condensation build up on the air conditioning duct and also to prevent heat/cooling loss. As the foil face on the insulation is perforated, it absorbs sound so to deaden any sounds that might travel through the ducting from the air conditioner.
