FGIA Updates Flashing Document

The Fenestration and Glazing Industry Alliance has updated AAMA 711-20, Specification for Self-Adhering Flashing Used for Installation of Exterior Wall Fenestration Products. The specification establishes minimum performance requirements for self-adhering flashing surrounding common exterior fenestration products. Originally created in 2007, this is its second update, having last been 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," says Jim Katsaros, chair of the FGIA flashing committee. "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."

Per Katsaros, this update of 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.

AAMA 711-20, as well as other AAMA documents available from FGIA, may be purchased from the online store at the discounted member rate of $20 or the non-member price of $60.
