• Apply to wall and floor-ceiling assemblies where airborne sound transmission and structurally transmitted sound are a concern.
• Mold and moisture resistant, provides extra protection against mold and mildew.
• Type C core is fire resistant and an approved component in UL fire-rated designs.

3/4" Gold Bond® SoundBreak® XP® Fire-Shield C™ 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. The acoustically enhanced, fire-resistant gypsum core is encased in heavy, 100% recycled paper on both sides that offers superior abrasion, mold, mildew and moisture resistance.

SoundBeak XP Fire-Shield C Gypsum Board provides higher Sound Transmission Class (STC) and Impact Insulation Class (IIC) values than standard gypsum board when applied to the underside of floor-ceiling assemblies where airborne sound transmission and structurally transmitted sound are a concern.

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

For non-fire rated assemblies use Gold Bond® SoundBreak® XP® Gypsum Board.

APPLICATIONS:

• Apply it to wall and floor-ceiling assemblies where airborne sound transmission and structurally transmitted sound are a concern, and high Sound Transmission Class (STC) and Impact Insulation Class (IIC) values are desired.
• Use to provide a 1-hour fire-rating in specific UL floor-ceiling designs.

ADVANTAGES:

REDUCES SOUND TRANSMISSION

• Provides high Sound Transmission Class (STC) and Impact Insulation Class (IIC) values per an independent third-party acoustical laboratory using ASTM E90 test procedures.
• In specific floor-ceiling assemblies, provides both STC and IIC ratings above 60.

PROVIDES ADDITIONAL FIRE RESISTANCE

• Features a Type C core that is more fire resistant than ordinary wallboard.
• Approved for specific UL fire-rated designs.
• 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 the GridMarX guide marks on the board to allow for faster and more accurate installation.
• Installs like traditional gypsum board, without requiring additional clips and/or channels.
• Use according to specifications to achieve the highest possible sound ratings.
• Heavy abrasion-resistant paper and a dense core that provides greater resistance to surface abuse and indentation when tested in accordance with ASTM C1629.

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.

LOW-EMITTING MATERIALS

• Qualifies as a low-emitting material per California Section 01350 and CDPH Standard Method, v1.2. For more information, visit: calrecycle.ca.gov
• Achieves UL GREENGUARD Gold Certification for low chemical emissions into indoor air during product usage. For more information, visit: ul.com/gg
