One of the most critical issues for architects is ensuring that building design addresses fire safety issues. This resource lists fire-resistant assemblies using USG products and systems, as well as the related evaluation reports. The results of acoustical tests are also included, where relevant.

Shaftwall Assemblies

Use this brochure to determine fire ratings for USG products and systems. USG is the undisputed leader among building material manufacturers in providing products and systems designed to keep people safe from fire.

Fire safety properties are described in terms of fire resistance, surfaceburning characteristics and noncombustibility. The period of time the assembly will serve as a barrier to the spread of fire and how long the assembly can function structurally after it is exposed to a fire of standard intensity as defined by ASTM E Sometimes this is also called the assembly's fire endurance.

Refers to material that may ignite but will not sustain a flame. Class A products will not gener. Class A is not a fire-resistance designation. Fire-resistance ratings have long been used by UL, ASTM and building codes to measure the performance of various constructions for fire containment purposes. As applied to elements of buildings, the fire-resistance rating classifies the ability of an assembly to confine and isolate fire within a zone comprised of fire resistance-rated walls, ceiling and floor assemblies.

The ratings relate to fire tests designed to determine how quickly fire can raise the temperature to unacceptable levels.

Fire-rated assemblies are tested and certified in their entirety. These designs are identified in the UL Fire Resistance Directory, which is updated yearly and can be referenced at the Underwriters Laboratories web site at www. If you have additional questions regarding fire protection, use the following resources: USG Literature. The sections listed below correspond to the different types of assemblies in which USG products are tested.

Each section is arranged sequentially according to fire ratings, the criterion that most often governs selection. Each entry within a section contains a reference to the source for more information within the Architectural Reference Library binder.

Basic methods of protecting columns and beams with gypsum base and veneer finishes, mineral fireproofing, and gypsum drywall. Fire and sound tested assemblies listed in this Selector are based on characteristics, properties and performance of materials and systems obtained under controlled test conditions as set forth in the appropriate ASTM Standard in effect at the time of test. These listings are short summaries to serve as a compilation and guide of construction assemblies available in the selection process.

For complete information on construction details and components used in these systems, refer to the individual Folder reference. USG Corporation will provide information for published fire, sound and structural data covering systems designed and constructed according to its published specifications. Tests are conducted on Company products assembled to meet performance requirements of established test procedures specified by various agencies.

System performance following any substitution of materials or compromise in assembly design cannot be certified and may result in failure under critical conditions. Sound tests are conducted under controlled laboratory conditions according to ASTM procedures. Comparable field performance depends on building design and careful attention to detailing and workmanship.

Certain sound tests, conducted in accordance with ASTM methods, measured sound transmission of 11 frequencies.Fire-Resistant Assemblies Brochure English Recommend Documents.

The test evaluates the assembly's resistance to heat, and in some instances to a hose stream, while carrying an applied load, if the assembly is load bearing.

In some instances, the fire exposure may be followed by the application of a specified standard fire hose stream. This exposure by itself may not be representative of all fire conditions; conditions may vary with changes in the amount, nature, and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment.

These requirements provide a relative measure of fire performance of comparable assemblies under these specified fire exposure conditions. Any variation from the construction or conditions that are tested such as size, method of assembly, and materials, may substantially change the performance characteristics of the assembly. These requirements prescribe a standard fire exposure for comparing the performance of building construction assemblies.

Application of these test results to predict the performance of actual building construction requires careful evaluation of test conditions.
