Abstract
A window wall system includes a plurality of window wall modules for forming at least in part a facade of a building. Each window wall module is connected between two consecutive concrete slabs of the building and includes a bottom rail, a top rail, two vertical mullions, and a window panel. The system also includes a plurality of anchoring brackets for connecting the bottom rail of each window wall module to a respective one of the concrete slabs, and a plurality of preformed sealing membranes. Each anchoring bracket is configured to be affixed to a top surface of the respective one of the concrete slabs. Each sealing membrane sealingly engages the bottom rail of a corresponding window wall module. Each sealing membrane is interlocked with a respective one of the anchoring brackets to retain the sealing membrane in place. Each sealing membrane is made of an elastomeric material.
