Hollow glass is made of two or more pieces of glass original, separated by an isolation frame around it and sealed with sealant, so that a dry air layer is formed between the glass layers. Hollow glass according to the plane shape of square and rectangular. The inspection items of sealing, dew point, ultraviolet irradiation, climate cycle, high temperature and high humidity performance of insulating glass must be qualified, otherwise it will be judged as unqualified product.

Hollow glass has good heat insulation and sound insulation effect, and its appearance has good aesthetic applicability, but now more and more manufacturers of insulating glass are producing insulating glass, and many inferior hollow glass appear on the market. For those who do not understand, they will be deceived and buy some fake and shoddy products. Let's talk about the harm of inferior insulating glass.

1. Poor quality hollow glass appearance transparency, energy saving, insulation performance impact: insulating glass due to the selection of unqualified desiccant or sealant caused by condensation, salting out, dust pollution, volatiles pollution, transparency is reduced, can not see the situation outside the window, and lost the good effect of energy saving, heat preservation, sound insulation.

2. Influence on its safety performance: The hollow glass is caused by the selection of unqualified desiccant (large inspirations) or the original glass (uneven thickness), and the temperature difference causes the pressure difference between inside and outside the insulating glass, resulting in glass damage, which can lead to major accidents, especially the high-rise exterior glass. Once the glass explodes or falls off, the consequences are unimaginable.
3. Increase the cost: when the service life of empty glass has to be replaced, it will inevitably increase the burden of society and cause a huge waste.
