Strategic Placement for Maximum Effectivenes

Randomly placing panels yields suboptimal results. Tu specifically target sound bleed between rooms, follow these placement principles.

On thee rediedving side, panels absorb noise that ents the share wall before it can bounce around the quiet room.

Foam panels are often tremed with fire relecdants but may still burn. For installations in commerciali buildings, schools, or healccare facilities, always specify panels that complex with NFPA 286 or UL 723. Addionally, ensure that adheaciives and mounting hardware not create fire hazard.
