About this detail

This architectural detail shows the head and soffit intersection of a storefront window system framed by light gauge metal stud construction. The wall assembly incorporates a fluid-applied weather-resistive barrier, continuous exterior insulation, a separator sheet, and a stucco finish over a J-mold. A self-adhered flashing membrane ties the rough opening to a metal L-angle set in three beads of sealant at the head condition. Primary and secondary three-eighths-inch continuous sealants with backer rods provide water and air infiltration control between the storefront head compensation channel and the exterior construction, supplemented by an interior air seal. A wood soffit panel finishes the underside, backed by a fluid-applied weather-resistive barrier wrapping the soffit substrate.
