Abstract

An improved curtain wall casing bead for installation on buildings having stucco or similar curtain wall exteriors. The improved curtain wall casing bead incorporates a mesh attached to at least the front wall of the casing or starter bead, which mesh extends beyond the height of the front wall and provides additional area for the infiltration of over-applied stucco finishes or the like. Such additional infiltration, after drying of the over-applied layer provides a more adherent, higher quality and more durable attachment of the stucco finish to the casing bead and the overall wall structure is achieved.

Claims

1. A curtain wall casing bead comprising:

a) a base having front and rear elongated edges and upper and lower surfaces;

b) a nailing flange extending upward from said base along said rear elongated edge at an angle greater than about 90° and

including an outside surface;

c) an upright elongated front flange extending upward from said base approximately parallel to said nailing flange along said front elongated edge and including an outside surface; and

d) a mesh including openings therein attached to said upright elongated front flange outside surface and said base lower surface, said mesh extending upward from said base beyond said upright elongated flange.

2. A curtain wall casing bead comprising:

a) a base having front and rear elongated edges and upper and lower surfaces;

b) a nailing flange extending upward from said base along said rear elongated edge at an angle greater than about 90° and

including an outside surface;

c) an upright elongated front flange extending upward from said base approximately parallel to said nailing flange along said front elongated edge and including an outside surface; and

d) a mesh including openings therein attached to said upright elongated front flange outside surface, said base lower surface and said nailing flange outside surface, said mesh extending upward from said base beyond said upright elongated flange.
