EXPANDED METAL LATH ASSOCIATION (EMLA) DEVELOPS TABLES OF TRANSVERSE LOAD CAPABILITIES FOR LATH & PLASTER IN WALL ASSEMBLIES
The Expand Metal Lath Association (EMLA) of the National Association of Architectural Metals Manufacturers (NAAMM) has run a comprehensive testing program to determine the minimum acceptable load for expanded metal lath for transverse loading with a traditional 3-coat stucco wall system. The third party test results proved these types of wall systems perform exceptionally well in high-wind zone environments. The stucco tests were performed in August, 2011 at Smith-Emery Laboratories in Los Angeles, CA, following the ICC’s – Acceptance Criteria (AC) 191 – Acceptance Criteria for Metal Plaster Bases (Lath) – using Code-Compliant Lath & fasteners, studs, weather-barrier and sheathings. The test frames were constructed in accordance with AC191 and the lath plaster were installed according to ASTM C-1063 – Standard Specification for Installation of Lathing and Furring to Receive Interior and Exterior Portland Cement-Based Plaster and ASTM C-926 Standard Specification for Application of Portland Cement-Based Plaster.
