Sound Control Without the Demolition
- Apply over existing gypsum board walls where sound transmission is a concern.
- Improves sound control without demolition.
- Mold and moisture resistant, provides extra protection against mold and mildew.
5/16" Gold Bond® SoundBreak XP Retrofit® Gypsum Board consists of a high-density, mold- and moisture-resistant gypsum board with specially designed PURPLE® paper on the front and a sound-damping, viscoelastic polymer adhered to the back paper. This acoustically enhanced, fire-resistant gypsum core is encased in heavy, 100% recycled paper on both sides that offers superior abrasion, mold and moisture resistance.
Use SoundBreak XP Retrofit on one side of a gypsum board wall to improve the acoustical performance by creating a constrained damping layer when installed over the existing surface.
GridMarX® installation guide 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.
If looking to reduce sound transmission in new construction, try Gold Bond® SoundBreak® XP® Gypsum Board.
APPLICATIONS:
- Use to improve the acoustical performance of an existing wall assembly, and to achieve a higher Sound Transmission Class (STC) rating for existing interior gypsum board walls where sound transmission has become a concern.
- Install over existing interior gypsum board walls in residential, multifamily and commercial applications for additional sound damping between rooms or dwelling units.
ADVANTAGES:
REDUCES SOUND TRANSMISSION
- When installing over an existing interior wall assembly, it enhances Sound Transmission Class (STC) values per an independent third-party acoustical laboratory using ASTM E90 test procedures.
- Achieves increased STC values in a thinner wall assembly, increasing usable floor space.
- Superior sound damping, cost-efficient material that finishes easily and decorates in the same manner as standard gypsum board.
WORKS FOR INTERIOR PROJECTS
- Heavy abrasion-resistant paper and dense core provide greater resistance to surface abuse when tested in accordance with ASTM C1629.
- Fire-resistant material with a gypsum core that will not support combustion or transmit temperatures greatly in excess of 212°F (100°C) until completely calcined, a slow process.
- The 5/16" thickness provides a superior sound solution without taking up usable floor space
INSTALLS FAST AND EASY
- Offers quick installation and lower installation costs, with vertical board joints that do not require acoustical sealant.
- Installs over existing construction, eliminating the need for demolition.
- Features GridMarX guide marks on the board to allow for faster and more accurate installation.
- Easily scored and snapped to exact size without sawing.
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-VOC emitting material by meeting California Specification 01350. 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
