Saddle Flashing Detailing, Mock-ups, and Construction Sequencing

This course was initially presented at the 2021 International Convention and Tradeshow.

Water-related damage is common at parapet terminations with high-rising walls that lack proper integration of the four primary control layers. The speaker has found that except for EIFS manufacturers’ standard details, there are little to no industry-recognized saddle flashing details available at this time to provide guidance to design professionals and contractors for the integration of the four primary control layers. Construction documents often do not include saddle flashing details or specification requirements, and consideration needs to be given to construction sequencing when developing the details. Due to the lack of industry-recognized details, a set of multi-step isometric details was developed by Michael Nagle, showing the integration of the air/weather-resistive barriers, roofing membrane, through-wall flashing, and sheet metal flashing for inclusion in one or more industry-recognized detail manuals. He recently collaborated with the International Masonry Institute (IMI) to construct saddle flashing mock-ups with the assistance of a manufacturer and multiple contractors. The mock-ups will be used as educational tools for masons, roofers, and design professionals. This presentation will provide beneficial guidance to building enclosure consultants, design professionals, building owners, facility managers, and manufacturers.
