The invention relates to a novel nanometer heat insulation glass wool, and belongs to the technical field of heat insulation material. The novel nanometer heat insulation glass wool comprises a fibergrid layer, a glass wool layer, and a heat insulation layer; one side of the glass wool layer is provided with the fiber grid layer; and the other side of the glass wool layer is provided with the heat insulation layer. According to the novel nanometer heat insulation glass wool, a nanometer particle layer 1 and a nanometer particle layer 2 are arranged in the glass wool layer; the nanometer particle layer 1 and the nanometer particle layer 2 are formed by different nanometer particles of the same thickness; the existing of the nanometer particle layers is capable of increasing the heat insulation efficiency of the glass wool greatly; at the same time, a plurality of heat insulation air channels are arranged between the nanometer particle layer 1 and the nanometer particle layer 2, becauseof the low air heat conduction coefficient, the existing of the air channels is capable of improving the heat insulation effect of the novel nanometer heat insulation glass wool, and widening the market application range of the novel nanometer heat insulation glass wool.
