This is the special glass component that consisted of two or more pieces of glasses and aluminum alloy frame with contain desiccant. The glasses are conglutinated on edge with the frame by binding agent that is high in intensity and air-seal. Therefore, the hollow glass can prevent the transmission of heat and sound on both side of the glass effectively. It is good in heat insulation, sound insulation, and heat preservation. It is also energy-saving, frost proofing and dew proofing. And the life-span is up to 10 years.
