AAMA Updates Liquid-Applied Flashing Guideline
The American Architectural Manufacturers Association has recently updated specifications establishing minimum performance requirements for liquid-applied flashing.
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, of DuPont Building Performance Solutions, 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.”
The association notes that the AAMA 714 document sets minimum performance and durability requirements for these materials, helping to ensure proper function in end use and that both the International Residential Code and the International Building Code reference AAMA 714.
AAMA adds that three levels of heat exposure classification are established in this specification.
