The Fenestration and Glazing Industry Alliance (FGIA) updated a document serving a recommended practice for determining test methodology for laboratory and field testing of exterior wall systems.
The document pertains to products covered by an AAMA standard such as curtain walls, storefronts, window walls, and sloped glazing. AAMA 501-24, Methods of Test for Exterior Walls was last updated in 2015. The mandatory and optional test methods outlined in the document are used to evaluate the performance of a complete system and shall not take the place of structural calculations and/or accepted engineering practice.
Test methods, specifications, field tests, and checks referenced in this document are used to check the structural adequacy of wall system test specimens and their ability to resist water penetration and air leakage. Also referenced are optional tests for thermal cycling, inter-story displacement, static and dynamic seismic racking, acoustical performance, and thermal performance, some of which require additional test specimens.
“The document had a very thorough review and revision performed to clarify how it could be used for a variety of purposes which had been outside of the limited scope of previous editions,” said Rich Rinka, FGIA technical manager, Fenestration Standards and U.S. Industry Affairs. “To help make the document a little easier to use, the tests have been placed into a table that provides a logical sequence for the testing to be conducted and highlights required tests and optional tests.”

The perception that the U.S. has not been able to curb development in flood-prone areas is mostly inaccurate, according to new research from climate adaptation experts. A national survey of floodplain development between 2001 and 2019 found that fewer structures were built in floodplains than might be expected if cities were building at random.
