In accordance with various embodiments, there is provided an interlocking rolling sheet door and a method for assembling the interlocking rolling sheet door. In accordance with at least one embodiment, the interlocking rolling sheet door includes at least one curtain panel. Each curtain panel includes a first curl on a lateral end and a second curl on an opposing lateral end. One of the first curl and the second curl is an interior curl portion, and the other of the first curl and the second curl is an exterior curl portion. The first curl of one curtain panel is configured to rotationally engage an inner portion of the second curl of an adjacent curtain panel, whereby the first curl rotationally engaging the second curl until a distal end of the first curl fouls out against an inner surface of the second curl. The first curl and the second curl are configured to rotationally engage one another to form an interlocking mechanism between adjacent curtain panels to form the interlocking rolling sheet door.

A retractable curtain system is provided and includes a curtain support system, a curtain, and a retraction system. The curtain support system includes a pair of outer walls and an upper frame to provide a curtain receiving space. The curtain covers the curtain receiving space and includes a first non-transparent panel and transparent panel connected to the first non-transparent panel. The retraction system is connected to the curtain to lower and raise the transparent panel.

In some embodiments, a nesting grille may include an alpha link having a top alpha link grommet, a beta link, and a plurality of cross members. In some embodiments, each of the plurality of cross members are coupled to at least one of the alpha link and the beta link. In one embodiment, the top alpha link grommet is configured to receive one of the plurality of cross members. In one embodiment, the grille is configured to be moveable between an extended state and a retracted state, the grille coiled about itself with the alpha link disposed inside of the beta link when the grille is in the retracted state.
