About this detail

The assembly features a 2.5-inch by 6-inch front-glazed aluminum-framed storefront system with a 3-part PVDF finish, shimmed as needed and sealed at the base with backer rod and sealant. WP-10 aluminum-faced self-adhered flashing laps over a termination bar above a minimum 22-gauge aluminum flashing with a 3-part PVDF finish matching the storefront mullions. A paverfaux wood decking system on sleepers rests on the exterior assembly, positioned adjacent to a WP-9 single-ply roofing membrane over tapered insulation, 5/8-inch exterior roof sheeting, and a WP-11 vapor barrier. The entire roofing and decking build-up is supported by a stepped structural slab.
