1. A method of installing a box assembly into a curtain wall construction, the method comprising:
positioning the box assembly, and
applying a force to rip a hole in a door of the box assembly, thereby allowing a foam in an interior space of the box assembly to at least partially extend into a safing slot or building joint of the curtain wall construction,
wherein the box assembly in an uninstalled state comprises:
a box;
the door, enclosing the interior space of the box assembly;
an opener configured to open the door; and
an insulation material in the interior space of the box,
wherein the insulation material is in a compressed state in the interior space when the door is closed, and wherein the insulation material is configured to transition to an uncompressed state when the opener opens the door, the insulation material configured to at least partially extend from the interior space into a safing slot adjacent the curtain wall when the box is in an installed state and the door is opened,
wherein the opener includes a string coupled to the door,
wherein the string is configured to apply a force to rip a hole in the door, to allow the insulation material to at least partially extend from the interior space and transition to the uncompressed state, and
wherein the insulation material comprises the foam, which is in a compressed state in the interior space when the door is closed.
