Product catalog summary
Market Trends and Need for Higher STC Wall Partitions
Due to increasing land costs, there is a growing demand for high-density multi-family housing, which requires improved sound control between units. The popularity of home theatre systems and the need for sound control in commercial buildings like schools and hospitals have also driven the demand for higher Sound Transmission Class (STC) wall partitions.
Gold Bond® SoundBreak® XP® Gypsum Board
This product is engineered for high STC wall assemblies, providing a thinner, cost-effective, and reliable alternative to traditional methods. It features a high-density gypsum core with a viscoelastic damping polymer for enhanced sound damping.
Understanding Airborne Sound and STC Ratings
Airborne sound is energy transmitted through a medium and detected by a receiver. STC ratings measure a material's ability to reduce sound transmission, with higher values indicating better performance. An ideal STC rating for wall partitions is 55 or higher, with 60 being more effective for eliminating noise disturbances.
Design Considerations for Acoustical Wall Partitions
Factors affecting sound transmission loss include mass, stiffness, damping, cavity depth, and cavity absorption. Increasing mass and cavity depth, using metal studs, and adding sound-absorbing materials can improve sound insulation.
Product Features and Benefits
SoundBreak XP Gypsum Board is mold and moisture resistant, provides superior sound damping, and is easy to install. It is GREENGUARD certified for indoor air quality and can be used on walls and ceilings. The board is also fire-resistant and suitable for various applications.
Limitations and Installation Guidelines
The board should not be exposed to excessive moisture or temperatures above 125°F. Proper storage is necessary to prevent sagging and mold growth. Installation should adhere to specific standards, and accessories like acoustical sealants and putty pads are recommended for optimal performance.
Technical Data and Standards
SoundBreak XP Gypsum Board complies with several ASTM standards for fire resistance, mold resistance, and physical properties. It is available in different thicknesses and offers excellent surface abrasion and impact resistance.
Specifications
The document details installation specifications for various gypsum board assemblies, including types like Gold Bond Gypsum Board, SoundBreak XP Gypsum Board, and Fire-Shield Gypsum Board. Installation involves different configurations of wood and steel studs, with specific spacing and screw types for each layer. Glass fiber insulation is used in the stud cavities, with varying thicknesses depending on the assembly.
Procedures
Installation procedures specify the application of base and face layers of gypsum boards, with vertical application and staggered joints for enhanced soundproofing and fire resistance. Detailed instructions on screw placement and spacing for both wood and steel framing are provided.
Standards and Testing
The gypsum board assemblies are tested for STC ratings and fire ratings, referencing various test numbers and UL designations, indicating compliance with ASTM Standard E 119 and classification as Type X for fire resistance.
Recommendations
The document suggests using SoundBreak XP Gypsum Board as either a face or base layer in multi-layer systems without affecting the STC rating. It also provides contact information for technical support and customer service across different regions.
Warranty and Limitations
National Gypsum offers a limited warranty for its products, ensuring they are free from defects in materials and workmanship at the time of shipment. The warranty excludes all other express or implied warranties and limits liability to product replacement or credit. Claims must be submitted within 30 days of discovering a defect, and legal actions must be initiated within one year.
Key Data from Tables and Charts
The document includes STC ratings for different gypsum board configurations, with ratings ranging from 34 to 67, depending on the assembly type and construction method. Fire ratings are also provided, with some assemblies achieving up to 2-hour fire resistance.
