The American Architectural Manufacturers Association (AAMA) updated and released a document specifying the performance requirements for liquid-applied flashing for water-resistive seals around exterior wall openings.
James Katsaros, chair of the AAMA Flashing Task Group, says the document provides rigorous material specification requirements for a new class of flashing products used in the building industry.
“These liquid-applied flashings have many advantages over traditional flashing products, including ultimate conformability for complex geometries and the potential for vapor permeability,” Katsaros said. “But, they still must demonstrate the durability and gap bridging properties of conventional flashing materials. The AAMA 714-15 specification ensures that these property requirements are met for the successful use of these products.”
Changes to AAMA 714-15, Voluntary Specification for Liquid-applied Flashing Used to Create and Water-resistive Seal Around Exterior Wall Openings in Buildings, include:
- definitions of the minimum requirements for adhesive bond and accelerated aging;
- updated reporting requirements; and
- the use of mortar slabs replaced by anodized aluminum strips for water immersion testing.
AAMA also released updated aluminum finish documents: AAMA 612-15, Voluntary Specification, Performance Requirements, and Test Procedures for Combined Coatings for Anodic Oxide and Transparent Organic Coatings on Architectural Aluminum, and AAMA 2603-15, Voluntary Specification, Performance Requirements, and Test Procedures for Pigmented Organic Coatings on Aluminum Extrusions and Panels (with Coil Coating Appendix).
All updated documents can be purchased from the Publication Store.
