Hollow glass is a deep-processed glass product in which two or more pieces of glass are effectively supported and evenly spaced and bonded and sealed to form a dry gas space between glass layers. Compared with ordinary glass, hollow glass has better heat insulation and sound insulation. There are two types of metal spacers, hollow glass and composite rubber insulating glass. The insulating glass of metal spacers mostly uses polysulfide rubber or silicone seal groove aluminum double channel sealing structure, and the composite rubber strip insulating glass adopts single-channel sealing or double-channel sealing structure. Because insulating glass has the functions of heat insulation, energy saving and sound insulation, it has now been widely used in building curtain wall glass, door and window glass, household appliances and transportation. The use of hollow glass, especially Low-E (low-emissivity coating) insulating glass, in the construction field has been growing rapidly year by year. >>>Related Links: Five Tips to Identify the Advantages and Disadvantages of Insulating Glass Doors and Windows When purchasing insulating glass, pay attention to the following aspects: First, look at the logo to check the certificate Architectural (safety) Insulating glass means that the monolithic glass that constitutes the insulating glass is a safety glass (tempered glass or laminated glass) that has passed 3C certification. In 2006, building (safety) insulating glass was included in the compulsory certification of safety glass products. Since the implementation of the certification, many manufacturing companies have obtained 3C certificates through product certification. Companies should screen-seal or paste the 3C logo on the sold product itself, or add the 3C logo to their minimum packaging and accompanying documents (such as certificates of conformity). When purchasing a product, it is first necessary to check whether there is a 3C mark, and check whether the manufacturer of the product has passed the mandatory product certification (there is a 3C certificate and is valid) through the network based on the company information, factory number, or product certification certificate. Whether the specification is within the capability of the company that has passed the compulsory certification, and whether the status of the certification certificate is valid. Second, look at the quality of appearance Look at the quality of the product's appearance. Hollow glass should not interfere with see-through stains, inclusions, and sealant splashes. Intermediate spacers should not have any foreign matter. Sealant or rubber strip coating should be uniform and continuous, and it should be firmly bonded to the glass surface. No airway or air bubbles should appear. The width and depth of the sealant must not be less than the requirements of the GB/T11944-2002 standard. Third, send samples to qualified testing agencies for testing to confirm product quality Hollow glass products have many key raw materials and production processes. The quality of raw materials and the control of production processes affect the final quality of products. And the key performance of insulating glass can not be identified from the appearance of the product, only through the test test can confirm. Therefore, it is recommended that when purchasing insulating glass, especially when the volume is large, it must be sent to a third-party testing agency for inspection. IV. Confirmation of Energy Saving Performance of Insulating Glass In the design of curtain wall glass and building doors and windows, there are certain requirements for the visible light transmittance, shading coefficient, heat transfer coefficient, dew point and other performance parameters of insulating glass. In order to improve the energy-saving effect of hollow glass, people use different types of coated glass and colored glass to synthesize hollow glass. The original glass sheet and structure of the insulating glass are different, and the energy saving performance of the product is different. Therefore, before the choice of insulating glass, we must first send the glass to a qualified third-party testing agency for testing and confirmation, in order to ensure that the selected product performance meets energy-saving design requirements or energy-saving building exterior window performance requirements. When using high-permeability Low-E coated insulating glass, because the coated surface is placed inside the compartment, it is difficult to be identified and detected. Therefore, it is absolutely necessary to sample the products provided by the insulating glass supplier, and ask a professional inspection agency to make a screening to prevent it from filling up, even as a result. Fifth, the handling, storage and use of insulating glass Hollow glass is generally packaged in wooden boxes or pallets. Glass is separated by plastic or paper, and light and soft materials are used between the glass and the package to prevent scratches on the glass. Hollow glass should be stored vertically in a dry room, and it should be avoided when handling and using it. Be careful not to scratch or scratch the glass surface when cleaning the glass.

ICESUN Vacuum Glass LTD. adopts the unique vacuum eye technology to produce Gen3 vacuum glass with mirror eye. This mirror eye technology refers to place the nano active sodium barium film with the size of pupil in the vacuum chamber. When it encounters trace gas, the eye of vacuum glass would immediately undergo chemical reaction and change from black and bright mirror into white powder. The disappearance of the mirror eye indicates the increase of conduction and convection in the vacuum glass, and also indicates that the Low-E film will soon be oxidized and fail, and the radiation heat transfer would greatly increase. That is to say, the building glass will fail. Therefore, users can easily know the service life of their own windows at any time through installing our Vacuum Glass For Buildings. Besides, our company also provide other good quality and high performance Vacuum Glass For Transportation like cars, Vacuum Glass For Passive House, Vacuum Glass For Sun Room and skylight, etc.
