Patent attributes
When assembled to a building support structure to form a curtain wall system of adjoining panels, a preferred embodiment of the enhanced airloop wall system as shown in FIG. 2 comprises panel frame segments that, when assembled, form interconnected inner and outer airloop segments that separate and improve water seal and air seal functions and improve sealing performance, a circuitous path (e.g., “A”) at an enlarged air opening into an airloop to pressure equalize and limit water entry into the airloop, a two point fastener support of each panel assembly to allow interfloor deflections under seismic or other loads without excessive loads on the panel assembly, a structural hook-like protrusion for resisting building outward loads on panels separate from fasteners, a splitter in a drainage cavity in the outer airloop that creates a dual drainage path and a surface upon which droplets can collect.
