Independent sealing structure, adopting a hard seal three sealing structure and two soft seal, has excellent air tightness and water tightness to reduce noise, use of different thickness of hollow glass structure and heat insulation broken bridge aluminum cavity structure, can effectively reduce acoustic resonance effect to prevent the transmission of sound, can reduce noise above. By properly using the heat insulation system, the energy consumption can be reduced and the environmental radiation produced by air conditioning and heating can be reduced.
