Essentials for insulating glass: energy saving, durability and seal life.

The main factors affecting the durability and sealing life of insulating glass are: insulating glass sealant, sealing structure, spacers, desiccant (molecular sieve), and the quality of manual operation. It has been proved that the sealing life of insulating glass with double seal, continuous spacer and 3A molecular sieve is the longest, while the sealing life of insulating glass with single seal, four-sided gusseted aluminum spacer and 4A molecular sieve is shorter. This is also confirmed by the 20-year tracking results of the North American Insulating Glass Association on the actual use of insulating glass. In addition, the results of the accelerated aging test of insulating glass (P1 test) show that the expected sealing life of insulating glass with different spacer sealing structures is very different, the shortest is only 2 months, and the long is more than 100 years.
