  • Isolates and dissipates noise
  • Blocks and absorbs sound

Trenwyth Acousta-Wal® Sound Absorbing Units are specifically designed to absorb sound waves so as not to reflect the energy, with NRC values up to .85 (up to 85% of sound is absorbed). STC values are also similar to typical concrete masonry.
