1.Non treated vacuum glass.
Till now,most vacuum protected glass made are at this point hardened VIG fixed with glass binds. The low strength of non-tempered glass, which is used in models like the Fineo, Spacia, and others, limits its extensive use in buildings.
2.Unstable quality.
The temperamental quality is achieved by multi factors,all these components lead to one outcome: Lopsided stress on glass and cause glass breakage.
Edge fixing development: Many glass producers detailed that they can make totally treated glass,but the glass tie edge fixing development has its gain inadequacy: The fixing framework will cause glass edge reinforce from now on and surface tension downfall by 10-15%,which will cause disproportionate strain on glass surface,causing high glass breakage proportion. In 2020, an endeavor took on vacuum protecting glass had 20-30% glass broken considering unbalanced quality.
Gutters: The channels are embed inside glass,whether it's round shape or stripe shape along the glass edge,processors need to make grooves on glass ,while this will impact the glass strength too.
Clearing openings: The exist of takeoff holes,not simply impact the visual appearance,but similarly impact glass strength as well,the strength center at glass openings will have high breakage extent.
Supporting support points. A few makers use Round and empty shape supporting pillars,when putting the help focuses on glass,there'll be some losing, or can't maintain glass because of glass flatness,or huge distance between pillars,these will provoke the assembled strain in the supporting places of help.

3.Max size imperative.
As of now most assembling plants max size reach 1500*2500mm, while still can't be by and large used in glass veneer which for the most part contain glass sheets over 3000mm,which make it can't be used as exterior glass .
4.High cost.
Although the price of vacuum glass is currently decreasing, it is still several times the price of standard double glass units. In extension to the high risks( glass breakage,glass failing, etc) ,land originators modeler really keep careful attitude while picking the glass things for their endeavors.
