1/2 in x 4 ft x 10 ft National Gypsum Gold Bond BRAND SoundBreak XP Gypsum Board

Gold Bond® BRAND 1/2" SoundBreak® XP® Gypsum Board with Sporgard™* has an acoustically enhanced, high density 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 1/2" 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.

Tapered edges allow joints to be reinforced with ProForm® BRAND Joint Tape and concealed with ProForm® BRAND Ready Mix or ProForm® BRAND Quick Set Setting Compounds. For optimum mold and mildew performance, ProForm® BRAND XP Ready Mix is recommended for use.

Basic Uses

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

Advantages

• 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 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.
• 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 power saw.
• Provides greater resistance to surface abuse and indentation over standard gypsum board.
• Heavy abrasion resistant paper and denser core provide greater resistance to surface abuse and indentation when tested in accordance with ASTM C 1629.
