If your problem is that the movie wakes the kids upstairs or annoys a neighbor, panels will not help you and this will.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt works by adding mass to the wall assembly. Sound has to move that mass to get through, and limp vinyl is very hard to move. It's most effective as one layer in a multi-layer build — pair it with decoupling (resilient clips and hat channel) and acoustical sealant at the perimeter for a real isolation system.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eNote that this is a construction material.
