1/2 in x 4 ft National Gypsum Gold Bond SoundBreak XP Wall Board


Turn down the volume when you incorporate SoundBreak XP Wall® Board into your wall assemblies. You will dramatically reduce sound transmission between rooms or dwelling units with this superior sound-damping gypsum board. SoundBreak XP has an acoustically enhanced, high-density gypsum core encased in heavy, abrasion and mold/mildew/moisture resistant, 100% recycled PURPLE® paper on both sides. Plus, SoundBreak XP provides the same great mold-inhibiting qualities as XP Gypsum Board.

  • 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.
  • Provides high-rated Sound Transmission Class (STC) values per an independent third-party acoustical laboratory using ASTM E90 test procedures.
  • Achieves high STC values in a thinner wall assembly, increasing usable floor space.
  • Provides STC Ratings up to 56 for single-layer, steel stud partitions and up to 67 for area separation walls.
  • Superior sound damping, cost-efficient material that finishes easily and decorates in the same manner as standard gypsum board.
  • For speed of installation and lower installation costs, vertical board joints do not require acoustical sealant.
  • Resists the growth of mold per ASTM D3273 with a score of 10, the best possible score.
  • Resists the growth of mold per ASTM G21 with a score of 0, the best possible score.
  • Heavy abrasion-resistant paper and dense core provide greater resistance to surface abuse and indentation when tested in accordance with ASTM C1629.
  • Installs like traditional gypsum board without requiring additional clips or channels.
  • Cuts by scoring deeply from both sides before snapping or by using a hand or power saw.
  • Fire-resistant material will not support combustion or transmit temperatures greatly in excess of 212 °F (100 °C) until completely calcined, a slow process.
  • Dimensionally stable product with negligible expansion and contraction under normal atmospheric conditions.
  • Features the GridMarX® guide marks on the board to allow for faster and more accurate installation.
  • Achieves GREENGUARD and GREENGUARD Gold Certification. GREENGUARD Certified products are certified to GREENGUARD standards for low chemical emissions into indoor air during product usage. 
  • Qualifies as a low-VOC emitting material by meeting California Specification 01350. 

Gold Bond® SoundBreak XP Wall® Board has achieved GREENGUARD Gold Certification.
