Sir, isme dono layer ke bich me vacuum kiya jata hai. Vacuum nahi karenge to ye insolation ka kam nahi karega.

[@Technicalmukesh7]

Vacuum Insolation hone ke wajah se hi isko vacuum flask bola jata hai.
Pahle glass Insolation wala aata tha jisme glass tut jata tha to wo khrab ho jata tha,
Ye vacuum Insolation jadi khrab nahi hota hai
