Helps reduce floor-ceiling sound transfer

Features acoustically enhanced, fire-resistant gypsum core

  • Mold & Mildew Resistance
  • Sound Resistance
  • Fire Resistance

SoundBreak XP Ceiling® 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 paper that is 100% recycled on both sides and offers superior abrasion, mold, mildew and moisture resistance.

Applications

  • Apply to 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 3/4" (19.1 mm) SoundBreak XP Ceiling Board to provide a 1-hour fire-rating in specific UL floor-ceiling designs.
  • For speed of installation, GridMarX® guide marks are printed on the paper surface.

Advantages

  • 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.
  • 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
  • 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. For more information, visit: ul.com.
  • Qualifies as a low-VOC emitting material by meeting California Specification 01350. For more information, visit: calrecycle.ca.gov.
