SoundBreak XP® Wall Board
Acoustically Enhanced High-Density Gypsum Wall Board
Turn down the noise 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 superior mold-inhibiting qualities.
Reduces Sound Transmission
- Has a layer of viscoelastic damping polymer sandwiched between two pieces of high-density, mold-resistant gypsum board
- Provides high-rated Sound Class Transmission (STC) values per an independent third-party acoustical laboratory using ASTM E90 test procedures
Works For Interior Projects
- Use in a single layer or as a component of multi-layer wall assemblies
- Thinner than traditionally built high-STC wall partitions, increasing usable floor space
- Available in 1/2" and 5/8" (5/8" features a fire-resistant Type X core and is UL Classified)
- Provides greater resistance to surface abuse and indentation than standard gypsum board (per ASTM C1629)
Installs Fast And Easy
- Installs like traditional gypsum board, without requiring additional clips and/or channels
- Finishes and decorates as easily as standard gypsum board
- For speed of installation, GridMarX® guide marks are printed on the paper surface.
- Can cut by scoring deeply from both sides before snapping or by using a hand/power saw
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
- Has less than 5% water absorption per ASTM C473
Resists Moisture Better
- Fights the effects of moisture before damage can occur
- Helps to reinforce the structure’s integrity and strength
- Reduces or eliminates swelling or dimensional movement caused by moisture
Use it for interior wall assemblies, where sound transmission between rooms or dwelling units is a concern. 5/8" SoundBreak XP Wall Board may be used where Type X Gypsum Board is specified in fire-rated assemblies.
Acoustically enhanced high-density mold-resistant gypsum core with inner layer of viscoelastic damping polymer. Wrapped with 100% recycled PURPLE paper on both sides.
