Gypsum industry news

US: The Gypsum Association (GA) has announced the release of the 21st edition of the Fire Resistance Design Manual (FDRM) GA-600-2015.

Revised on a three-year basis, GA-600 has been referenced by the model building codes as a source of fire resistive designs for more than 40 years. The 2015 edition contains nearly 100 new systems that supplement existing assemblies for walls and partitions, floor-ceiling systems, area separation walls and others. Among these are 20 new head-of-wall and base-of-wall systems that expand the options for perimeter relief.

The FRDM is currently referenced by the International Building Code and The National Fire Codes, as well as many state and local jurisdictions in the US and Canada as a source document for fire-resistance and sound-control rated designs that incorporate gypsum board in a variety of building systems. A recently revised ICC-ES Evaluation Report (ESR 1338) incorporates a reference to the 2015 edition of the Fire Resistance Design Manual as an acceptable source of generic fire-resistance and sound-control systems. Over the years, the FRDM has broadened to address sound and other factors of concern for designers, builders, code officials and the public, featuring more than 700 systems.
