This Manual is a convenient and useful specification
\naid for anyone concerned with the design, construction,
\nor inspection of fire resistive and sound control systems.
\nDesign information is quickly and easily determined.
\nComparison of these characteristics allows the user to
\nbe more accurate in meeting design and code
\nrequirements. The data provided are especially useful to
\nbuilders, architects, code officials, fire service, and
\ninsurance personnel.<\/p>\n
The systems in this Manual utilize gypsum products
\nto provide fire resistance to walls, partitions, floor-
\nceilings, roof-ceilings, columns, beams, girders, and
\ntrusses. Systems are classified according to their typical
\nuses and their fire-resistance ratings. Walls, partitions,
\nand floor-ceiling systems are further classified by Sound
\nTransmission Class (STC) or Field Sound Transmission
\nClass (FSTC). The Impact Insulation Class (IIC) is
\nincluded for many wood framed floor-ceiling systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
