Thin hollow glass with composite structure

The invention discloses thin hollow glass with a composite structure, which is applied to an external window of a building, and comprises outdoor side glass, indoor side glass and outdoor side glass, a gap is formed between the indoor side glass and the outdoor side glass, and a sealed cavity is formed; the thin glass is arranged in the sealing cavity between the outdoor side glass and the indoor side glass; the thickness of the thin glass is smaller than that of the outdoor side glass and that of the indoor side glass. According to the invention, the thickness of the middle glass of the three-layer hollow glass is reduced, so that the middle glass becomes thin glass, the whole structure is thin, and the inner side glass, the outer side glass and the middle glass are thinned relative to the original glass, so that the material consumption is reduced during manufacturing, and the hollow glass is convenient to transport and install. The inert gas filled in the sealed cavity is one or more of krypton gas, mixed
