A flame retardant insulation module according to one embodiment of the present invention comprises: an air layer-forming part including a first air layer-forming part and a second air layer-forming part disposed below the first air layer-forming part, which are disposed so that at least a portion of one does not overlap with a portion of the other; a lower end cover part that covers the lower end of the second air layer-forming part to separate the lower end from an external space; and an intermediate separation part for separating a first air layer and a second air layer. As such, heat insulation performance can be maximized, such that the insulation module has flame retardancy even when a fire occurs. |
