The American Architectural Manufacturers Association (AAMA) announced an update to AAMA 2502-19, its standardized comparative analysis procedure for determining the structural integrity of door and window products.
The document, titled Comparative Analysis Procedure for Window and Door Products, was last updated in 2007.
“New content in the 2019 version of this standard includes guidance for unit sizes smaller and larger than those tested as well as deflection and stress limits established by industry standards,” said Kawneer manager of new product development Tanya Dolby who is also the chair of the Requirements for Mulled and Combination Window Assembly (AAMA 450/2502) Update Task Group.
“These key changes increase the applications where AAMA 2502-19 can be utilized to support a larger range of unit sizes,” Dolby said.
Regions where the performance of exterior door and window size is documented to meet specific structural design pressure criteria will find the AAMA 2502-19 especially useful.
For door and window manufacturers, the procedure provides a uniform approach for dealing with different code jurisdictions and specific design pressure for each size of fenestration product opening.
