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 in buildings.
The standard applies to fenestration products, such as windows and doors, as well as other through-wall penetrations. AAMA 714-19, “Voluntary Specification for Liquid Applied Flashing Used to Create a Water-Resistive Seal around Exterior Wall Openings in Buildings,” was last updated in 2015.
“Liquid-applied flashing products are seeing increasing application for sealing building interfaces, including flashing around windows and doors,” said Jim Katsaros (DuPont Building Performance Solutions), chair of the AAMA Flashing Committee, in an AAMA news release. “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.”
The AAMA 714 document also sets minimum durability requirements for these materials. Both the International Residential Code and the International Building Code reference AAMA 714.
