Abstract: A curtain wall (ACM) system has vertical mullions and horizontal supports which provide a dry as well as a structural system for non-sequential construction of curtain wall exteriors. Internal gutters offer a failsafe moisture proof system. The horizontal and vertical framework members may be mounted in the reverse orientation for special exterior wall configurations. Individual panels can be replaced without sealants or tear down of neighboring panels. A face support for the thin ACM panels is provided. Thermal expansion is addressed with a floating panel on a track design. Alternate embodiment includes transition frame members having glass and metal panel integral supports, freestanding X-Y sub-frame assemblies, fiber optic outboard channels and novel methods of assembly.

Abstract: Both positive and negative wind loads acting on the surfaces of standing seam roofing often exceed the design capabilities of a particular metal roof, causing the standing seam interlocking vertical seams to disengage. This often results in the roof panels blowing off the roof, causing damage to the roof, the building contents and possible danger to people in the vicinity. A transverse bar is provided across the standing seams of the metal roof. Clamps hold the transverse bar onto the standing seams. At the midsection of each flat panel section of the metal roof a brace descends from the transverse bar. The brace must have a flexible foot member to press down on the panel, otherwise the brace would puncture or otherwise damage metal roof panel. The brace may have an adjustable height adjustment mechanism. Various clamp, bar and foot embodiments are disclosed, all of which provide a structural anti-lift bracket on the roof panel.
