Heat insulation double-layer hollow glass energy-saving door and window

The utility model relates to the technical field of door and window systems, and provides a heat insulation double-layer hollow glass energy-saving door and window, which is characterized in that a sealing structure is designed into a structure with two slots, and the sealing structure is sleeved in a fixing groove, so that glass is directly mounted in the slots instead of being directly mounted in the fixing groove. Therefore, when the glass is inserted into the slot, the gravity of the glass can be applied to the bottom edge of the sealing structure, so that the bottom edge of the sealing structure has downward and inward pulling force on the side edge sealing body. As the abutting edge of each side edge sealing body abuts against the end part of the fixing groove, the end part of the fixing groove has an upward abutting force towards one side of the glass on the side edge sealing bodies, so that the side edge sealing bodies are tightly attached to one side of the glass. Thus, by means of the installation e
