Sound Proof Panel


Rockwool Acoustic Infills combine optimal density, random fiber orientation, and excellent fit to provide a significant improvement in sound absorption when used within the troughs of perforated metal roof decks. The product is wrapped in a factory-applied acoustically transparent white tissue facing for improved aesthetics. For the best performance.

A noise barrier is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. Noise barriers are the most effective method of mitigating roadway, railway, and industrial noise sources.

Factors should be considered while designing noise barriers:

  • Sound barrier location
  • Material
  • Design and shape of barrier
  • Wind speed calculations
  • Noise calculations
  • Structural stability
  • Aesthetic values

Noise barrier has the 3 layered structure

1. The first layer is the perforated metal sheet :
The common material of perforated metal sheet is galvanized steel, aluminum, Mild steel, or powder coated steel sheets.
2. The second layer is sound absorbing rockwool infill :
The sound absorbing rockwool has excellent sound or noise absorbing performance, it can reduce the noise and keep the atmosphere quite. The main infill material is rockwool.
3. The third layer is metal sheet :
The material of metal sheet is same as the perforated metal sheet, But there is no any hole on the metal sheet.
