AlphaPerf® Metal Cloud

The AlphaPerf® Metal Cloud is used primarily as sound a sound absorber in noisy environments such as gymnasiums, swimming pools, pump rooms and industrial fabrication work areas.

These acoustical cloud panels consist of a corrugated metal skin with an encapsulated acoustical insulated material. The corrugated metal skin allows sound waves to enter the sound absorbing material where the sound waves are then turned to energy.

Features:

  • Elegant aesthetic
  • Variety of sizes and colors
  • Reduce reverberation and echo
  • Impact Resistance
  • Improves speech intelligibility
