Description
Gold Bond® BRAND SoundBreak™ Gypsum Board is an
acoustically enhanced gypsum board 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 enhanced 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 Sta-Smooth Joint Compounds.
Applications
- 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.
Features & Benefits
- Use of SoundBreak 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 regular gypsum board.
- All SoundBreak Gypsum Board designs were tested by an independent third-party
acoustical laboratory using the full scale ASTM E90 test procedure.
- SoundBreak 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 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.
Fire Resistance Ratings
As an option, SoundBreak Gypsum Board may be used as an additional layer on one or both sides
of fire-rated wall assemblies (i.e., U300, W300, U400, W400 and V400 series designs). SoundBreak Gypsum
Board cannot be used as a substitute for 5/8" Type X gypsum board in a fire-rated assembly.
SoundBreak Gypsum Board shall be attached in accordance with manufacturer's
recommendations. When SoundBreak Gypsum Board is installed between
the framing and the UL/ULC Classified gypsum board, the UL/ULC Classified gypsum board layer(s)
required for the design is/are to be installed as indicated in the design as to fastener type
and spacing, except that the required fastener length shall be increased by a minimum of 5/8" (16 mm).
For U300, W300, U400, W400 and V400 series designs, outer layer treated with joint compound and paper
tape as specified in the design.

and Accessories.
Mold and Mildew Resistance*
SoundBreak Gypsum Board was designed to provide extra protection against mold and mildew
compared to standard gypsum board products. When tested by an independent lab per ASTM D
3273 ("Standard Test Method for Resistance to Growth of Mold on the Surface of Interior
Coatings in an Environmental Chamber"), SoundBreak Gypsum Board achieved a score of 10,
the best possible score for this test.
*No material can be
considered "mold-proof", nor is it certain that any material will resist mold or mildew
indefinitely. When used in conjunction with good design, handling and construction
practices, SoundBreak Gypsum Board can provide increased mold resistance versus standard
gypsum board products. As with any building material, avoiding water exposure during
handling, storage and installation, and after installation is complete, is the best way to
avoid the formation of mold or mildew.
