Building curtain wall sealing system
Disclosed is a bridging member, formed of flexible or non-flexible material, for use with a curtain wall system for building exteriors. The curtain wall system includes a vertical mullion operable to attach to a horizontal member. A sealing member is secured in a void created by the intersection of the vertical mullion and the horizontal member. The sealing member includes a substantially planar top surface and a lip portion extending from a bottom surface of the sealing member.
1. A curtain wall system comprising:
a vertical mullion for attaching to a support structure of a building;
a horizontal member for intersecting with said vertical mullion; and
a unitary bridging member for completely sealing a void between said horizontal member and said vertical mullion, said bridging member including a body including a mating region and an edge, said body being substantially planar; a mouth region disposed on a bottom surface of said body, said mouth region having a body portion extending outwardly from the body and a curved lip portion extending from said body portion in a direction substantially parallel to said body; wherein said mating region abuts said horizontal member of said curtain wall system, and said edge abuts said vertical mullion of said curtain wall system; and wherein said curved lip portion engages said horizontal member of said curtain wall system in a space formed between said lip portion and said bottom surface.
2. The curtain wall system of claim 1 , wherein said vertical mullion includes a support surface and said horizontal member includes a web portion, and wherein said bridging member abuts said support surface and said web portion.
3. The curtain wall system of claim 1 , wherein said lip portion is disposed between said mating region and said edge of said body.
4. The curtain wall system of claim 1 , wherein said body is oriented at an angle between said horizontal member and said vertical mullion.
5. The curtain wall system of claim 1 , wherein said bridging member is formed of a flexible material.
6. The curtain wall system of claim 1 , wherein said bridging member is molded.
7. The curtain wall system of claim 1 , wherein said bridging member is extruded and cut to size.
8. The curtain wall system of claim 1 , wherein said vertical mullion and said horizontal member are formed of aluminum.
9. The curtain wall system of claim 1 , wherein said vertical mullion is formed as a single extrusion.
10. The curtain wall system of claim 1 , wherein said horizontal member is formed as a single extrusion.
11. The curtain wall system of claim 1 , wherein said vertical mullion is formed from multiple extrusions.
12. The curtain wall system of claim 1 , wherein said horizontal member is formed from multiple extrusions.
13. The curtain wall system of claim 1 , wherein the bridging member is formed of non-flexible material.
