The Gypsum Association has announced the release of the 2010 edition of its publication, GA-216, Application and Finishing of Gypsum Panel Products. GA-216 is a code-referenced industry standard that describes the proper methods and materials for most applications of gypsum panel products in the built environment.
Included in the document are instructions for the proper delivery and handling
of gypsum panels, single- and multi-layer applications over both wood and steel
framing, installation of semi-solid gypsum panel product partitions, adhesive
application to a variety of substrates, gypsum panel product application over
rigid plastic foam insulation, exterior applications of exterior gypsum soffit
board, and the finishing of gypsum panel products. Also included are
recommendations for special situations, including floating angles, outside
corners, arches, and curves.
The 2010 edition of GA-216 includes new language reflecting changes in ASTM C
1396 and ASTM C 1658, changes terminology from metal gauges to base metal
thickness to reflect practices of the steel framing industry, and revises the
recommendations for water-resistant gypsum tile backer board to comport with
companion specifications found in the tile industry’s TCNA Handbook and ANSI A
108, which are also now required in the ICC codes.
The new 2010 edition of GA-216 is available from Association’s on line
bookstore at www.gypsum.org.
