Gold Bond® SoundBreak XP Retrofit® Board consists of a high-density mold-, mildew- and moisture-resistant gypsum board with specially designed PURPLE paper on the front and a sound- damping, viscoelastic polymer adhered to the back paper. This acoustically enhanced, fire-resistance gypsum board is encased in heavy paper that is 100-percent recycled on both sides and offers superior abrasion, mold-, mildew- and moisture-resistance.

Applications

• Use SoundBreak XP Retrofit to improve the acoustical performance of an existing wall assembly, and to achieve a higher Sound Transmission Class (STC) rating for existing interior gypsum board walls where sound transmission has become a concern.
• Install 5/16 in. (7.9 mm) thick SoundBreak XP Retrofit over existing interior gypsum board walls in residential, multifamily and commercial applications for additional sound damping between rooms or dwelling units.

Advantages

Reduces Sound Transmission

• When installing over an existing interior wall assembly, SoundBreak XP Retrofit enhances Sound Transmission Class (STC) values per an independent third-party acoustical laboratory using ASTM E90 test procedures.
• Achieves increased STC values in a thinner wall assembly, increasing usable floor space.
• Superior sound damping, cost-efficient material that finishes easily and decorates in the same manner as standard gypsum board.

Works for Interior Projects

• Heavy abrasion-resistant paper and dense core provide greater resistance to surface abuse when tested in accordance with ASTM C1629.
• Fire-resistant material with a gypsum core 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

• For speed of installation and lower installation costs, vertical board joints do not require acoustical sealant.
• Features GridMarX® guide marks on the board to allow for faster and more accurate installation.
• Easily scored and snapped to exact size without sawing.

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-VOC emitting material by meeting California Specification 01350. For more information, visit: calrecycle.ca.gov
