Vacuum insulating glass lifetime
Vacuum insulating glass is mainly used in building envelope and industrial products (such as freezer doors , car and ship windows, etc.), and has to withstand the repeated effects of sunlight and high and low temperature changes during its lifetime. Te time to maintain its good performance is the key to the survival and development of vacuum glass as an industrial product. Vacuum glass is different from laminated glass or insulated glass that contain organic materials: Laminated glass contain PVB or SGP interlayer,during its lifetime,rain/temperature and humidity will affect the interlayer and cause bubbles around glass edge,or delamination problem after years. Insulating glass contains butyl and silicon sealant, the rubble or sealant will aged and decrease its lifetime after years as well,IGU max lifetime is 25 years. Tempered glass has no lifetime as well,it can work if only glass don’t break. Different from above normal ar...
