Abstract

A mullion cover hanger and a curtain wall insulation system incorporating the mullion cover hanger are provided. The mullion cover hanger includes an elongated main body having hook members extending therefrom. When the mullion cover hanger is attached to a mullion, a mullion cover can be secured to the mullion cover hanger without using electric tools or additional fasteners.

First claim

What is claimed is:

1. A curtain wall insulation system for insulating a curtain wall structure connected to a building structure, the curtain wall structure spaced from a floor slab of the building structure to define a perimeter void and the curtain wall structure having framing defined by at least first and second vertically disposed and parallel mullions, at least one upper horizontally disposed transom, and at least one lower horizontally disposed transom, the curtain wall insulation system comprising:
a curtain wall insulation disposed within the framing and attached to the framing;
a safing insulation disposed within the perimeter void and compression fit between the curtain wall insulation and the floor slab;
a mullion cover hanger attached to the mullions, the mullion cover hanger having:
a main body having a top surface, a bottom surface, a first side edge, and a second side edge; and
a plurality of hook members extending outward relative to the top surface of the main body; and

a mullion cover attached to the mullion cover hanger.

2. The curtain wall insulation system of claim 1 , wherein a lower mullion cover is attached to the mullion cover hanger such that a top surface of the lower mullion cover abuts a bottom surface of the safing insulation, and an upper mullion cover is attached to the mullion cover hanger such that a bottom surface of the upper mullion cover abuts a top surface of the safing insulation.

3. The curtain wall insulation system of claim 1 , further comprising a reinforcement member attached to and disposed between the mullions and behind the curtain wall insulation, and positioned at a level corresponding to a level of the safing insulation.

4. The curtain wall insulation system of claim 1 , wherein a hook member positioned at a first side edge of the main body of the mullion cover hanger is parallel to a hook member positioned at a second side edge of the main body of the mullion cover hanger.

5. The curtain wall insulation system of claim 1 , wherein an angle between each hook member and the top surface of the main body is 90°.

6. The curtain wall insulation system of claim 1 , wherein the mullion cover hanger further comprises at least one fastening aperture that extends from the top surface of the main body through the bottom surface of the main body.

7. The curtain wall insulation system of claim 6 , wherein at least one fastening aperture is positioned between the first side edge and a centerline of the main body, and at least one fastening aperture is positioned between the second side edge and a centerline of the main body.

8. The curtain wall insulation system of claim 1 , wherein the hook members of the mullion cover hanger are defined by:
an upper edge that extends outward relative to the top surface of the main body at a first angle from the horizontal;
a lower edge that extends outward relative to the top surface of the main body at a second angle from the horizontal;
a topmost edge; and
a hook edge;
wherein the upper edge terminates at the hook edge;
wherein the lower edge terminates at the topmost edge;
wherein the topmost edge extends toward the top surface of the main body and terminates at the hook edge; and
wherein the first angle is less than the second angle.

9. The curtain wall insulation system of claim 8 , wherein the first angle is 0° to 50° and the second angle is 20° to 70°.

10. The curtain wall insulation system of claim 8 , wherein the first angle is 0° to 10° and the second angle is 20° to 40°.

11. The curtain wall insulation system of claim 1 , wherein the hook members of the mullion cover hanger extend outward relative to the top surface of the main body by a distance of 1 inch to 2 inches.
