ABSTRACT:
Disclosed is a roof structure containing a fire retardant. The roof structure has a fluted deck with troughs therein and a meltable insulation layer overlying the fluted deck. The fire retardant includes a series of non-flammable absorbent strips or strip segments which can be placed in the troughs of the fluted deck for retarding the flow of molten insulation in the trough during a fire by absorbing the molten insulation material in the trough.
