4 Sided Captured System Window WallS-4500 Window Wall offers a single infill plane for both vision and span-drel areas of a building while delivering the cost savings of a slab-to-slab framing system. Multiple system depths provide the flexibility needed to address a wide variety of applications found in today’s urban environ-ments. The integral slab bypass is designed to provide maximum design flexibility to accommodate a range of infill and insulation thickness at the face of the slab.
