INTRODUCTION

NOTE: This Introduction constitutes an essential part of the system descriptions contained in Section IV. It is important that the user be familiar with this introductory material.

This Manual is a convenient and useful specification aid for anyone concerned with the design, construction, or inspection of fire resistive and sound control systems. Design information is quickly and easily determined. Comparison of these characteristics allows the user to be more accurate in meeting design and code requirements. The data provided are especially useful to builders, architects, code officials, fire service, and insurance personnel.

When differences occur between provisions of this Manual and the appropriate building code or regulation, including provisions of other standards referenced in the code or regulation, the most stringent provision shall apply.

The systems in this Manual utilize gypsum products to provide fire resistance to walls, partitions, floorceilings, roof-ceilings, columns, beams, girders, and trusses. Systems are classified according to their typical uses and their fire-resistance ratings. Walls, partitions, and floor-ceiling systems are further classified by Sound Transmission Class (STC) or Field Sound Transmission Class (FSTC). The Impact Insulation Class (IIC) is included for many wood framed floor-ceiling systems.

WHERE THE WORD "PROPRIETARY" APPEARS IN SYSTEM DESCRIPTIONS EITHER THE SYSTEM OR ONE OR MORE OF ITS COMPONENTS IS CONSIDERED PROPRIETARY. EACH PROPRIETARY SYSTEM SHALL BE BUILT UTILIZING THE COMPONENTS SPECIFIED BY THE COMPANY OR COMPANIES LISTED UNDER THE DETAILED DESCRIPTION FOR THAT SYSTEM. ALL OTHER SYSTEMS ARE GENERIC. GENERIC SYSTEMS ARE APPLICABLE TO THE PRODUCTS OF ANY MANUFACTURER, WHETHER A MEMBER OF THE GYPSUM ASSOCIATION OR NOT, PROVIDED THE PRODUCTS MEET THE APPROPRIATE STANDARDS LISTED IN SECTION I AND, WHEN APPLICABLE, THE REQUIREMENTS SET FORTH IN SECTION II.

To maintain industry-wide quality assurance standards for gypsum board defined in this Manual as "type X," the Gypsum Association requires that all companies listing proprietary tests or systems, or relying on the generic systems in this manual, shall subscribe to an on-going third-party, in-plant product inspection and labeling service. Additionally, each member company makes annual written certification to the Gypsum Association that its products manufactured for use in systems listed in this Manual continue to be inspected and labeled by an independent third-party testing service as listed on page 10.

Fire-resistance ratings, STCs, FSTCs, and IICs are the results of tests conducted on systems composed of specific materials put together in a specified manner. Substitution of other materials or deviation from the specified construction could adversely affect performance. For example, if batt or blanket insulation is shown, then it is a required component of the system. In each system containing batt or blanket insulation the insulation is specified to be either mineral or glass fiber and, for fire resistance, the system shall be constructed using the type specified.

Mineral fiber or glass fiber shall not be arbitrarily added to floor-ceiling or roof-ceiling systems to increase either STCs or R-values. This practice has been shown to reduce the fire-resistance rating. The addition of up to 163/4 inches of 0.5 pcf glass fiber insulation (R-40), either batt or loose-fill, to any 1- or 2-hour fire resistance rated floor-ceiling or roof-ceiling system having a cavity deep enough to accept the insulation is permitted provided that one additional layer of either 1/2 inch or 5/8 inch type X gypsum board is applied to the ceiling. The additional layer of gypsum board shall be applied as described for the face layer of the tested system except that the fastener length shall be increased by not less than the thickness of the additional layer of gypsum board.

The detailed descriptions for the systems included in this Manual are summaries. For complete information on the systems or components tested, the listing or test report should be reviewed. Details regarding generic systems may be requested from the Gypsum Association; details on proprietary systems are available from the companies listed for those systems.

For information on limiting heights of nonloadbearing steel stud walls and partitions see ASTM C 754, Standard Specification for Installation of Steel Framing Members to Receive Screw Attached Gypsum Panel Products, or steel stud manufacturer's literature.

References to ASTM standards, CAN/ULC standards, or other standards refer to the respective standard in effect on the date that the test was performed. Each test reference contains the test report date.

The information in this Manual is based on characteristics, properties, and performance of materials and systems obtained under controlled test conditions as set forth in the appropriate standards in effect at the time of the test. The Gypsum Association and its member companies make no warranties or other representations as to the characteristics, properties, or performance of any materials or systems in actual construction. No warranty or representation is made that any material or component of any system, other than the gypsum material used in such system, conforms to any standard or standards.
