Does the vacuum glazing feature better performance if its thickness is thicker?

Vacuum glass is a type of insulating glass that has a vacuum cavity between two tempered glass panes. It can effectively block thermal transmission and deliver high thermal insulation performance. However, the thickness of the vacuum glazing does not affect its performance much. According to a web search result, "the vacuum glass U value is usually 0.4-0.5, even if made into insulated vacuum glass or laminated vacuum glass, the U value won’t decrease much." Therefore, the statement "the thicker the vacuum glass, the better performance" is not true. Instead, the performance of vacuum glass depends more on other factors, such as the quality of the seal, the type of coating and the size of the unit.
