About this detail

An aluminum-framed window and curtain wall system bears on a concrete foundation with an interior finish floor assembly. The sill condition integrates a minimum twenty-two gauge aluminum flashing finished to match the curtain wall mullions with a three-part PVDF coating, lapped over a termination bar and WP-10 aluminum-faced self-adhered flashing. Waterproofing includes a manufacturer standard drainage board, WP-3 self-adhered membrane flashing, and a waterstop embedded in the concrete wall. Exterior hardscape meets the foundation below, separated by compressible fill with backer rod and sealant.
