中空钢化玻璃采用大宽度中空层，三道密封胶条（超强密封性），采用三元乙丙 EPDM 复合胶条，形成三密两腔密封结构，噪音环境下无共振现象，空间隔音体验极佳。中空铝条采用转角一体折弯技术，形成真空闭合环境。

The hollow toughened glass adopts a large width hollow layer, three sealing strips (super tightness), EPDM composite rubber strips to form a three-dense two-cavity sealing structure, and the hollow aluminum strip adopts corner bending technology to form a vacuum Close the environment.
