The fire curtain has a fire resistant inner curtain layer having a first width between first and second lateral edges, and a fire resistant outer curtain layer arranged opposite the inner layer and having first and second scalloped lateral edges varying between the first width and a second width less than the first width. The inner and outer layers are affixed to one another by horizontally oriented connection seams at the first width, the connection seams being configured so that the outer and inner layers are spaced apart by a plurality of baggy areas formed between adjacent connection seams.
