June 12, 2019 - 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 that includes 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. "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 sets forth minimum performance and durability requirements for these 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. Three levels of heat exposure classification are established in this specification.

AAMA 714-19, as well as other AAMA documents, may be purchased from AAMA's online store.
