How to choose the right vacuum glazing(I)?
2022-01-17


1.What tests do vacuum insulated glass need to undergo?
Vacuum insulated glass undergoes three types of testing: safety testing, aging testing, and online quality testing. Safety testing includes fragmentation test,  impact test, and wind resistance test. Aging testing includes: weathering resistance test and a sunlight resistance test. Quality testing includes an airtightness test and an online performance test.

2. What certificate does vacuum insulated glass need to obtain? What does a third-party authoritative certification tell you?
Qualified vacuum insulated glass needs to obtain three types of certification: product performance certification, safety certification, and qualification certification. The performance certification primarily certifies the performance in thermal insulation, noise reduction, and wind resistance. The safety certificates mainly include a safety glazing product certificate and certification for testing items required by RoHS directive. The qualification certificates mainly include: 3C certificate and green building materials and products certificate.

The third-party authoritative certification tells you that the vacuum insulated glass product made by the manufacturer is tested and certified in its performance, quality, and application.

3.What are the benefits of vacuum insulated glass by using metal sealing?
As the melting point of the metal sealing material is low, it will not cause the annealing of the tempered glass in the process of edge sealing. Secondly, the metal material has better malleability. When the vacuum glass in use is exposed to additional loads caused by temperature differences or other external forces, the metal sealing material can withstand more deformation and maintain a good sealing effect. These benefits of metal sealing make vacuum insulated glass more reliable and with better performance.

4. How to determine whether a manufacturer is a supplier of qualified vacuum insulated glass?
First, the manufacturer's vacuum insulated glass products should comply with the requirements of the national standards for vacuum insulated glass. Secondly, the manufacturer should have a well-functioning ISO quality management system. Finally, the manufacturer should have sufficient production capacity and experience with large enterprise applications. As a landmark in high-performance energy-saving glass products, the wide application of vacuum insulated glass will greatly reduce the consumption of building materials and energy, decrease carbon emissions in the construction field, and bring the general public healthy and sustainable quality of life.
