The reporting requirements were updated, and the use of mortar slabs was replaced by anodized aluminum strips for water immersion testing.
According to James Katsaros (DuPont Building Innovations), chair of the AAMA Flashing Task Group, this revised 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,” says Katsaros. “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.”
