Gold Bond® BRAND 5/8" SoundBreak® XP® Gypsum Board with Sporgard™* has an acoustically enhanced, high density fire resistant Type X gypsum core encased in a heavy, abrasion and mold/mildew/moisture resistant, 100% recycled, purple paper on both sides. Used in the construction of high rated STC wall assemblies, this 5/8" thick gypsum board consists of a layer of viscoelastic damping polymer sandwiched between two pieces of high density mold resistant gypsum board, providing constrained layer damping.

For speed of installation, GridMarX® guide marks are printed on the paper surface.

Long edges of the panels are tapered. Tapered edges allow joints to be reinforced with ProForm® BRAND Joint Tape and concealed with ProForm® BRAND Ready Mix, Easy Finish® BRAND Ready Mix or ProForm® BRAND setting compounds.

For optimum mold and mildew performance, National Gypsum recommends ProForm® BRAND XP Ready Mix.

Features & Benefits

• Resists the growth of mold per ASTM G 21 with a score of 0, the best possible score.
  
• Resists the growth of mold per ASTM D 3273 with a score of 10, the best possible score.
  
• Use of 5/8" SoundBreak XP Gypsum Board results in wall partitions with high rated STC values that are thinner than traditionally built high rated STC wall partitions, providing increased usable floor space.
  
• 5/8" SoundBreak XP Gypsum Board features a fire resistant Type X core to provide additional fire resistance ratings when used in tested assemblies.
  
• Superior sound damping, cost-efficient material that is easily finished and decorated in the same manner as standard gypsum board.
  
• All SoundBreak XP Gypsum Board designs were tested by an independent third-party acoustical laboratory using the full scale ASTM E90 test procedure.
  
• SoundBreak XP Gypsum Board is installed like traditional gypsum board, offering a more reliable and less complicated solution than alternative methods requiring clips and/or channels.
  
• SoundBreak XP Gypsum Board can be cut by scoring deeply from both sides of the board before snapping, or with the use of a hand or electric saw.
  
• UL Classified and approved for inclusion in specific UL fire-rated designs.
  SoundBreak XP Gypsum Board is GREENGUARD Children & Schools Certified® for indoor air quality.
  
• Approved for use on walls and ceilings.

GREENGUARD Certified

5/8" SoundBreak XP Gypsum Board with Sporgard is GREENGUARD Children & Schools Certified® for indoor air quality.

The GREENGUARD Children & Schools Certified® Mark is a registered certification mark used under license through the GREENGUARD Environmental Institute.

The GREENGUARD Certification ProgramSM is an industry independent, third-party program that has been certifying products for low non-toxic emissions since 2001. To achieve GREENGUARD Indoor Air Quality Certified status, National Gypsum's products passed rigorous sample testing and review of the manufacturing processes to meet strict standards set by the GREENGUARD Environmental Institute (GEI) — a globally recognized leader in indoor air quality — to determine their impact on indoor air pollution. To achieve GREENGUARD Children & Schools Certification, SoundBreak XP Gypsum Board met even more stringent emissions limits that take into account the added sensitivity of children and adults with compromised immune systems.

Basic Uses

For use as a single-layer application or as a component of multi-layered wall assemblies where sound transmission between rooms or dwelling units is a concern.

5/8"SoundBreak XP panels may be used where Type X gypsum panels are specified in some fire-rated wall and floor-ceiling assemblies (e.g., UL U300, U400, V400 and L500 series).

Fire Resistance Ratings

Fire Resistance ratings represent the results of tests on assemblies made up of specific materials in a specific configuration. When selecting construction designs to meet certain fire resistance requirements, caution must be used to ensure that each component of the assembly is the one specified in the test. Further precautions should be taken that assembly procedures are in accordance with those of the tested assembly. For copies of specific tests, call 1-800-NATIONAL.
