Abstract

A box assembly includes a box, a door, an opener, and an insulation material. The box is configured to be installed on a curtain wall. The door encloses an interior space of the box. The opener is configured to open the door. The insulation material is in a compressed state in the interior space when the door is closed. The insulation material is configured to transition to an uncompressed state when the opener opens the door. When the door is opened, the insulation material at least partially extends from the interior space into a sating slot adjacent the curtain wall when the box is in an installed state and the door is opened.

First claim

The invention claimed is:

1. A building construction, comprising:
a curtain wall construction having an interior wall surface, a horizontal framing member, and a vertical framing member;
a floor spatially disposed from the interior wall surface of the curtain wall construction, thereby defining a safing slot between the curtain wall construction and an outer edge of the floor;
a steel cavity fastened via one or more screws to a lower side of the horizontal framing member, the steel cavity in at least partial horizontal alignment with the safing slot and having a concave portion facing the safing slot;
a first thermally resistant material disposed at least partially in the concave portion of the steel cavity; and
a second thermally resistant material disposed at least partially in the safing slot, and abutting the first thermally resistant material.

2. The building construction of claim 1 , wherein the steel cavity is concave in at least a side cross-sectional view of the building construction.

3. The building construction of claim 1 , wherein at least a portion of the interior wall surface of the curtain wall construction is glass.

4. The building construction of claim 1 , wherein a back of the steel cavity is positioned spatially disposed from the interior wall surface.

5. The building construction of claim 1 , wherein a back of the steel cavity is positioned spatially disposed from the glass.

6. The building construction of claim 1 , wherein the first thermally resistant material is a mineral wool, or wherein the second thermally resistant material is a mineral wool.

7. The building construction of claim 1 , wherein the first thermally resistant material is a mineral wool, and wherein the second thermally resistant material is a mineral wool.

8. The building construction of claim 1 , wherein the floor, the safing slot, the first thermally resistant material, the second thermally resistant material, and the steel cavity are all in at least partial horizontal alignment with one another.

9. The building construction of claim 1 , wherein the concave portion of the steel cavity has a depth of at least 3 inches and a height of at least 6 inches.

10. The building construction of claim 1 , further comprising a fire retardant coating on the second thermally resistant material.

11. The building construction of claim 1 , wherein the fire retardant coating is also on an adjacent portion of the horizontal framing member and on an adjacent portion of the floor.

12. The building construction of claim 10 , wherein the fire retardant coating is obtained by spraying.

13. A process for installing the building construction of claim 10 , the process comprising:
spraying a spray and thereby applying the fire retardant coating on the second thermally resistant material, on an adjacent portion of the horizontal framing member, and on an adjacent portion of the floor.
