AAMA Releases Updated Standard for Liquid-Applied Flashing on Exterior Wall OpeningsJune 12th, 2019 by Editor
The American Architectural Manufacturers Association (AAMA) has released an updated specification establishing minimum performance requirements for liquid-applied flashing used to provide water-resistive seals around exterior wall openings. The specification applies to buildings that include fenestration products, such as doors and windows, as well as other through-wall penetrations. The related codes were last updated in 2015, officials for AAMA said.
“Liquid-applied flashing products are seeing increasing application for sealing building interfaces, including flashing around windows and doors,” said Jim Katsaros, chair of the AAMA Flashing Committee. “These products offer many performance advantages, including outstanding adhesion to a wide variety of substrates, ultimate conformability for complex geometries and, in many cases, vapor-permeable water-resistant seals.”
AAMA document 714 sets forth minimum performance and durability requirements for related materials, helping to ensure proper function in end use. When making use of liquid-applied flashing during the installation of products, both the International Residential Code and the International Building Code reference AAMA 714.
This specification sets forth minimum performance levels, which enable the specifier to evaluate and select the liquid-applied flashing, and establishes three levels of heat exposure classification.
