Gypsum Association releases revised manual
The 162-page, 18th edition of the FRDM depicts more than 340 systems that may be used for fire-rated walls and partitions, floor-ceiling systems, roof-ceiling systems, and to protect columns, beams and girders. Included for the first time in this edition are several new floor- and roof-ceiling systems and double-stud steel partition designs.
This manual provides contractors, designers, specifiers, owners and others with a convenient compilation of the latest in tested gypsum-board designed fire-rated protection systems (as well as some tried and true older systems). It also helps building officials keep up with fire-rated gypsum board systems that are permitted under the codes.
The FRDM can be ordered through the association's Web site at www.gypsum.org.
