Use of SoundBreak XP Gypsum Board purple drywall 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.
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 purple drywall designs were tested by an independent third-party acoustical laboratory using the full-scale ASTM E90 test procedure.
Heavy abrasion resistant paper and denser core provide greater resistance to surface abuse and indentation when tested in accordance with ASTM C 1629.
Features a smooth, heavy face paper that is highly resistant to scuffing and provides a superior surface for decoration.
5/8″ SoundBreak XP sheetrock features a fire resistant Type X core and is UL Classified and approved for inclusion in specific UL fire-rated designs.
SoundBreak XP Gypsum Board is GREENGUARD Children & Schools^SM Certified for indoor air quality.
This soundproofing sheetrock is approved for use on walls and ceilings.

LIMITATIONS

Exposure to excessive or continuous moisture and extreme temperatures should be avoided. SoundBreak XP Gypsum Board is not recommended where it will be exposed to temperatures exceeding 125°F (52°C) for extended periods of time.
Installing SoundBreak XP Gypsum Board panels over an insulating blanket, installed continuously across the face of the framing members, is not recommended. Blankets should be recessed and flanges attached to the sides of the studs.
SoundBreak XP Drywall must be stored off the ground and under cover. Sufficient risers must be used to ensure support for the entire length of the gypsum board to prevent sagging.
SoundBreak XP Gypsum Board acoustic drywall must be kept dry to minimize the potential for mold growth. Adequate care should be taken while transporting, storing, applying and maintaining SoundBreak XP Gypsum Board. For additional information, refer to the Gypsum Association publication, “Guidelines for the Prevention of Mold Growth on Gypsum Board” (GA-238-03), which is available at gypsum.org under the “Download Free Gypsum Association Publications” section.

ACCESSORIES
