Sound Control and Damping

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

Gold Bond® SoundBreak XP Wall® 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® 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.

Combine with Gold Bond® SoundBreak XP Ceiling® Board to reduce sound between floor-ceiling assemblies.

APPLICATIONS:

  • Use it for interior wall assemblies, where sound transmission between rooms or dwelling units is a concern.
  • 5/8 in. (15.9 mm) SoundBreak XP Wall Board may be used where Type X Gypsum Board is specified in fire-rated assemblies.

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

  • Use 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.
  • Available in 1/2" and 5/8" (5/8" features a fire-resistant Type X core and is UL Classified).

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.

FIRE-RESISTANT MATERIAL

  • 5/8” SoundBreak XP Wall Board features a Type X core that is more fire resistant than ordinary wallboard.
  • 5/8” SoundBreak XP Wall Board is an approved component in UL fire-rated assemblies.
  • 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

  • Features GridMarX guide marks on the board to allow for faster and more accurate installation.
  • Save time and money with MaX 12® and MaX 16® optimized fastener patterns for 5/8” Fire-Shield products to achieve 1-hour fire ratings using fewer fasteners.
  • Installs like traditional gypsum board, without requiring additional clips and/or channels.
  • Finishes and decorates as easily as standard gypsum board.
  • Can cut by scoring deeply from both sides before snapping or by using a hand/power saw.
