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

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.

Works for Interior Projects

  • Heavy abrasion-resistant paper and dense core provide greater resistance to surface abuse and indentation when tested in accordance with ASTM C1629.
  • Fire-resistant material 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.
  • Use according to specifications to achieve the highest possible sound ratings.

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
