A Robust Installation for Brick-Mold Windows and Doors Using Self-Adhered Flashing
Current standardized practices for window and door installation methodologies are typically based on fenestration products that feature integral flanges that form a continuous surface to mount and integrate the fenestration product to the water resistive barrier (WRB)/drainage plane of the wall. While these types of units form the majority of fenestration products available, there are several “non-integral” flange type systems that are also utilized in the construction industry. These include “brick-mold” windows and doors, field-applied flange windows, and non-flanged “box” windows. Due to the discontinuity between the mounting system and the window frame, these types of fenestration systems pose special challenges to achieve a robust, continuous, and water-resistant integration between the fenestration product and the wall, which is not adequately addressed by ASTM E2112, “Standard Practice for Installation of Exterior Windows, Doors, and Skylights” or other standardized methods. The paper describes an installation method for windows and doors with factory-applied brick-mold exterior casings and presents the performance characteristics in laboratory testing of units installed using the method.
