AirLock Insulation can help you with your ACOUSTICAL COATINGS needs. Similar to water and air, sound travels in waves. Any opening in your structure that would allow water / air to leak in, will allow sound to leak in. Have you ever been bothered by that noisy TV in the room next door or the kids banging around upstairs? Inadequate sound barriers are to blame. Spray Foam Insulation can help because it is a tremendous sound insulator as well as thermal insulator.
