US 6,857,233 B2 · Fire resistant rated fenestration, including curtain wall systems, for multiple story buildings

Abstract

Apparatus and systems for a fire resistant rated fenestration including curtain wall systems for multiple story buildings capable of withstanding a seismic load. Fire resistant panels are mounted in a fire resistant mullion where the mullion may be one element, or may have an inner structural shell and an outer shell. A barrier of fire resistant material is disposed between the inner and outer shells. A sealer compound or a fire resistant compressible filler seals the space between the mullion and the fire resistant panels. The inner structural shell member is connected to an elastic panel fastener that is connected at its opposite end to fire resistant panels. The fastener allows the fire resistant panels to move in response to a seismic load without damage to the mullion or panels.
