Mullions, mullion components and assemblies, and methods of assembly and installation

A mullion assembly comprising:

• an outside member having
• an inner lip configured to engage an inside surface of a first window,
• an outer surface configured to engage an outside surface of the first window and an outside surface of a second window, and
• a depth spanning the depth of the first and second windows;
• a guiding profile having
• an inner lip configured to engage an inside surface of the second window, wherein the outside member and the guiding profile are physically separate elements;
• one or more mullion connectors configured to be positioned between and connect at least one of the outside member to the first window and the guiding profile to the second window;
• first and second reinforcement members, the first reinforcement member configured to attach to the outside member, the second reinforcement member configured to attach to the guiding profile, the first and second reinforcement members being configured to cooperate to reduce movement of the first and second windows parallel and perpendicular to the plane of the windows and be fastened proximate the inner surface of the windows;
• and
• a cap configured to cover the first and second reinforcement members, outside member, and guiding profile.

A method of assembling a mullion with two windows comprising:

• providing an outside member having
• an inner lip configured to engage an inside surface of a first window,
• an outer surface configured to engage an outside surface of the first window and an outside surface of a second window, and
• a depth spanning the depth of the first and second windows;
• providing a guiding profile having
• an inner lip configured to engage an inside surface of the second window, wherein the outside member and the guiding profile are physically separate and not directly attached;
• attaching a first reinforcement member to the outside member;
• attaching a second reinforcement member to the guiding profile;
• attaching the outside member to a side edge of the first window;
• attaching the guiding profile to a side edge of the second window;
• positioning the second window so the first and second reinforcement members cooperate to reduce relative movement between the first and second windows;
• and the outside surface of the second window engages the outer surface of the outside member;
• and
• fastening the first and second reinforcement members together.
