About this detail

This exterior detail shows a storefront sill assembly set atop a concrete topping slab and structural slab. The 2.5-inch by 6-inch front-glazed aluminum-framed storefront system features insulated glass units and is shimted and sealed with backer rod and sealant. Below the sill, minimum 22-gauge aluminum flashing with a 3-part PVDF finish laps over an aluminum-faced self-adhered flashing, which ties into the fluid-applied air barrier and waterproofing membranes. The adjacent wall construction consists of metal stud framing with 5/8-inch exterior gypsum sheathing, continuous mineral wool insulation, and flat aluminum panels with a PVDF finish.
