Sound Control and Damping

Dramatically reduce sound transmission between rooms
  • For interior walls and ceilings where sound transmission between rooms is a concern.
  • Provides high-rated Sound Transmission Class (STC) values.
  • Mold and moisture resistant, provides extra protection against mold and mildew.

1/2" Gold Bond® SoundBreak® XP® Gypsum Board consists of two pieces of high-density, mold-, mildew- and moisture-resistant gypsum board, with a specially designed PURPLE® paper, laminated together with a sound-damping viscoelastic polymer. This acoustically enhanced, fire-resistant gypsum core is encased in heavy, 100% recycled paper on the face and back sides and offers superior abrasion, mold, mildew and moisture resistance.

Use it for high-rated Sound Transmission Class (STC) wall and ceiling assemblies, where sound transmission between rooms or dwelling units is a concern.

GridMarX® installation guide marks are printed on the paper surface to help installers instantly identify stud locations and make accurate cuts without having to pencil in or snap chalk lines.

For UL fire-rated assemblies use Gold Bond® SoundBreak® XP® Fire-Shield® Gypsum Board or Gold Bond® SoundBreak® XP® Fire-Shield C™ Gypsum Board.

APPLICATIONS:

  • Use it for interior walls and ceilings in non-fire rated assemblies, where sound transmission between rooms or dwelling units is a concern.

ADVANTAGES:

REDUCES SOUND TRANSMISSION

  • Has a layer of viscoelastic damping polymer sandwiched between two pieces of high-density, mold-resistant gypsum board.
  • Provides high-rated Sound Class Transmission (STC) values per an independent third-party acoustical laboratory using ASTM E90 test procedures.

WORKS FOR INTERIOR PROJECTS

  • Can be used in a single layer or as a component of multi-layer wall assemblies.
  • Thinner than traditionally built high-STC wall partitions, increasing usable floor space.
  • Provides greater resistance to surface abrasion and indentation than standard gypsum board (per ASTM C1629).
  • The gypsum core will not support combustion or transmit temperatures greatly in excess of 212°F (100°C) until completely calcined, a slow process.

INSTALLS FAST AND EASY

  • Installs like traditional gypsum board, without requiring additional clips and/or channels.
  • Finishes and decorates as easily as standard gypsum board.
  • Features GridMarX guide marks on the board to allow for faster and more accurate installation.
  • Can cut by scoring deeply from both sides before snapping or by using a hand/power saw.

INHIBITS MOLD GROWTH

  • Helps inhibit mold growth with the highest possible score on mold tests (ASTM D3273 and ASTM G21).
  • Features SPORGARD® technology with extra mold-inhibiting properties.

RESISTS MOISTURE BETTER

  • Fights the effects of moisture before damage can occur.
  • Dimensionally stable product with negligible expansion and contraction under normal atmospheric conditions.
