The difference between vacuum glass and double or triple glazing

Double glazing and vacuum glass are both types of insulating glass used in windows and doors to reduce heat loss and improve energy efficiency. The main difference between the two is how they are constructed and how they provide insulation.

Double glazing

Double glazing, also known as insulating glass or thermopane glass, consists of two panes of glass sealed together with a space between them, usually filled with air or an inert gas such as argon. The space between the glass panels creates an insulating barrier, reducing heat transfer. Double glazing provides good insulation, reduces sound transmission and helps reduce energy loss.

Vacuum glass

Vacuum glass, also known as thermally insulated glass, consists of two glass panels sealed together with a complete vacuum between them. The vacuum creates exceptionally high thermal insulation because there are no air or gas convections between the glass panels. The vacuum minimizes heat transfer through conduction and convection, giving vacuum glass a very high insulation value and better energy efficiency than double-glazing.

Compared to double glazing, vacuum glass has some advantages, such as higher insulation value and thinner glass, making it suitable for applications where space is limited
