The Fenestration and Glazing Industry Alliance (FGIA) updated a specification establishing minimum performance requirements for self-adhering flashing surrounding common exterior fenestration products.
AAMA 711-20, Specification for Self-Adhering Flashing Used for Installation of Exterior Wall Fenestration Products, was created in 2007. This is the document’s second update. It was last updated in 2013.
“Self-adhered flashing products are broadly used at the window/wall interface to provide a durable moisture seal and enhance the long-term performance of the installation,” said Jim Katsaros (DuPont Performance Building Solutions), chair of the FGIA Flashing Committee, in a news release. “This document specifies essential material properties, such as adhesive bond strength to various building substrates, sealability through fastener penetrations, and weathering tests for UV and thermal exposure to help ensure the long-term performance of these products.”
The new AAMA 711 standard provides significant updates to select test methods, particularly regarding sealability through fasteners and new guidelines for minimum product width. AAMA 711 is referenced in both the IRC and IBC for the use of self-adhered flashing products around windows and doors.
