Insulating glass must meet two basic requirements that the energy saving, durability and seal life. If a piece of insulated glass energy saving effect of the poor, even if the durability and longer seal life, but also a low level of the insulating glass.  Conversely, if the energy-saving insulating glass performance good, but the durability and sealing a shorter life-span, nor is it pursued. Clearly, the ideal insulated glass should also have the best energy-saving effect and the longest durability sealed.

The impact of energy-saving insulated glass has a major factor in the performance of glass, interval article (box), and gas. Choose the glass side has white glass or Low-E glass; interval article has cold side (aluminum interval) or warm edge; gas there is air or inert gas such as argon.  At other conditions remain unchanged, the use of white glass, air and the cold side of the insulating glass energy saving effect of the worst, and the use of Low-E glass, argon filled insulated glass warmer side of the energy-saving best.

Affect the durability of insulated glass and sealed a major factor in life expectancy have insulated glass sealant, sealing structure, and spacing, the desiccant (molecular sieve) and so on.  Truth has been proved that the use of dual-channel sealing, continuous interval and 3A molecular sieves sealed insulating glass the longest life expectancy, and the use of single-channel sealing, four sidesaluminum and 4A molecular sieve interval of insulated glass sealing Life expectancy is shorter.  North American Association of insulation glass insulated glass actual usage of the 20-year follow-up results also confirmed this point.  In addition, the insulating glass accelerated aging experiment (PI detection) results showed that using different intervals closed structure sealed insulation glass Life expectancy difference between the expectations are enormous, just for a short period of 2 months, up to 100 long years.

At other conditions being equal, different spacing of Article insulation glass using a direct impact on energy-efficient performance and durable seal. However, in a fairly long period of time, the widespread use of aluminum Article interval (mainly for the four sides) Production of insulated glass, although a longer seal life, but high thermal conductivity, resulting in energy saving effect is poor, which directly reflected in the emergence of insulating glass edge condensation. In the 20th century, the end of the 70s, emerging composite tape has a low thermal conductivity characteristics, than the use of aluminum Article interval energy-saving insulating glass production has improved, but unfortunately at the same time reducing the seal life.

This unfortunately is also reflected in the traditional framework of thinking, no matter how hard and improvement of people to improve the energy efficiency of insulating glass improve the effectiveness and durability of seal life, are not exclusive.
