Sound-Reducing Gypsum Boards Are Thin and Easy
 National Gypsum earlier this month introduced Gold Bond® SoundBreak™ Gypsum Board, a cost-effective, acoustically enhanced panel that answers the growing demand for a product that reduces the transmission of airborne sound between living spaces within apartments, condominiums, townhouses and other buildings.
Using the new gypsum board results in wall partitions with high-rated sound transmission class (STC) ratings, helping to eliminate typical noises from adjacent rooms such as normal or loud conversation, a baby crying, a dog barking or the sounds of kitchen appliances. Because the board is thinner than traditionally built high-rated STC partitions, it provides more useable floor space.
In addition to its superior sound dampening, the 5/8-inch thick board is as easy to finish and decorate as regular gypsum board.
“SoundBreak installs and finishes like traditional gypsum board,” said Chris Pinckney, product manager of gypsum systems for National Gypsum. “It’s an alternative to existing sound-dampening solutions like double and staggered stud walls and sound clips or channels that can be difficult to install.”
The board can be used as a single-layer application or as a component of multi-layered wall assemblies where there is a concern about sound transmission between rooms or dwelling units. It is available in four-foot wide sheets that are 8, 9, 10 and 12 feet in length.
Though SoundBreak cannot be used as a substitute for 5/8-inch Type X board in a fire-rated assembly, it can be used as an additional layer in all UL fire-rate assemblies without compromising the fire rating. For example, upgrading a UL U465 with an additional layer of SoundBreak can increase its STC rating by seven to 10 points.
All SoundBreak Gypsum Board designs have been tested by Riverbank Acoustical Laboratories or the National Research Center of Canada using full-scale ASTM E90 test procedures.
