摘要： A roof structure (54) has a fluted deck (12) with troughs (26) therein, a meltable insulation layer (40) overlying the fluted deck (12) and a mass (64) of loose packed non-flammable granular material in the troughs (26). The mass (64) can consist of a plurality of spaced segments or can extend the entire length of the trough (26). The mass (64) retards the flow of molten insulation in the trough during a fire by absorbing the molten insulation material in the trough.
