Gypsum Association Releases New Edition of Application Standard
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.

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.
