Achieve a Higher Standard of Sound Control with SOUND CURB®

The Santa Clara Square high-end apartment complex in California experenced that firsthand. See case study for details.

Primary Uses

  • Interior floor/ceiling applications requiring enhanced acoustic performance
  • Ideal for multifamily residential and commercial applications
  • Fire-resistant high-density wallboard suitable for ceilings and walls

SOUND CURB® gypsum panels are ideal for floor/ceiling applications in multifamily residential and commercial projects. The 3/4” panels are comprised of a proprietary high-density Type X gypsum core and are perfect where fire resistance is a primary objective and additional mass is needed for improved Sound Transmission Class (STC) and Impact Insulation Class (IIC) performance. They also work well for lower frequencies where sound control has proven difficult.

The Type X gypsum core is wrapped in 100% recycled facing and backing paper that will accept most decorative finishes. Mineral additives have been integrated into the product’s core to enhance performance during exposure to fire.
