Abstract

The present invention is directed to a structure having a fire resistance rated, area separation wall including: a first building unit; a second building unit; and a two- hour fire resistance rated, area separation wall having only outer membranes. In the preferred embodiment, the two-hour fire resistance rated, area separation wall includes: (a) an interior support structure; (b) only an outer membrane on each side of the interior support structure; and (c) a substantially organic thermal insulation barrier between the outer membranes. Also, in the preferred embodiment, the structure having a fire resistance rated, area separation wall includes a tying structure connecting the fire resistance rated, area separation wall to the first unit and the second unit.
