The invention discloses composite profile energy-saving door and window. The composite profile energy-saving door and window comprise aluminum profiles, thermal insulation bars and sealing rubber strips, and hollow cavities are arranged between the aluminum profiles and the thermal insulation bars. The composite profile energy-saving door and window are characterized in that filling blocks are mounted in the hollow cavities, the filling blocks comprise hard blocks and soft blocks, and the soft blocks wrap the hard blocks, or the soft blocks and the hard blocks are overlapped. The composite profile energy-saving door and window have the advantages that machining and installing are convenient, excellent energy-saving and sound-proof effects are achieved, and meanwhile, thermal insulation bar deformation caused by preheating expansion is avoided.
