Primary Uses

  • Interior,   sound and fire rated ceilings applications
  • Multi-family residential and commercial buildings
  • Enhancing STC ratings in floor/ceiling designs

SOUND CURB™ panels with Quiet® core gypsum technology are engineered to reduce sound transmission in floor/ceiling applications. SOUND CURB™ panels are ideal for most multilevel residential or light-commercial projects where fire resistance is a primary objective and where additional mass is desired for improved Sound Transmission Class (STC) and Impact Insulation Class (IIC) performance, especially in lower frequencies where sound control is proven difficult.

The proprietary, high-density, Type X gypsum core is wrapped in 100% recycled facing and backing paper that will accept most decorative finishes. SOUND CURB® with Quiet core technology is intended for fire-rated interior ceilings in multi-family residential or commercial construction.

3/4" SOUND CURB™ with Quiet® core gypsum technology meets the requirements of Type X drywall by ASTM C1396.
