Welcome to Understanding the GA-600 Fire Resistance Design Manual!

Learning Objectives

Upon completion of this course you will have a better understanding of:

  • Terms used in GA-600 and how they are applied,
  • How a fire test is performed,
  • Basic conditions of sound control,
  • Information in GA-600 system descriptions,
  • How the General Explanatory Notes relate to system descriptions for sound and fire, and
  • Different types of systems in GA-600.

Review questions are interspersed throughout the course to aid in self-evaluation of your progress. These questions are not graded. You must complete the review questions to move through the course.

The course ends with a short quiz upon which you will be graded. A grade of 80% or better is required for credit or a Certificate of Completion.


The material is divided into learning modules. Each module covers a specific section of GA-600 and features one or more review questions. The individual modules are presented in the same order as the Table of Contents on pages 3 and 4 of GA-600-2018.

To gain a more thorough understanding of the material in each module, review the appropriate pages in GA-600 as you work your way through the course.

As you move through the course you will see that all of the listed systems are presented in a common format. Each listing contains the following components:

  1. The GA (Gypsum Association) File Number,
  2. A designation as either proprietary or generic,
  3. The fire resistance rating in hours,
  4. The STC (not all systems have up-to-date sound tests, some older systems are retained for historical information only),
  5. A short summary of its key components,
  6. A detailed description of how the components are assembled,
  7. One or more cross section details,
  8. A list of selected properties (weight, thickness, etc.), and
  9. Citations to the test or evaluation reports upon which the system is based.
