description The utility model relates to the technical field of coated glass, in particular to coated glass with a three-layer film structure, which comprises a glass base layer, a functional film layer, a PVB (polyvinyl butyral) film layer and an ultraviolet-proof film layer are sequentially arranged at the top of the glass base layer, a PVB film frame is arranged between the functional film layer and the PVB film layer, positioning grooves are arranged on two sides of the end face of the PVB film frame close to the PVB film layer, and the ultraviolet-proof film layer is arranged in the positioning grooves. According to the coated glass, the PVB film layer not only has higher light transmittance, but also has high infrared reflection capability and good heat insulation effect, and the PVB film frame is matched to form a heat insulation cavity between the PVB film layer and the functional film layer, so that the sound insulation and heat insulation performance of the coated glass is greatly improved; the surface of the g
