Double glazed glass, also known as insulated glass, is a type of glass that consists of two panes of glass separated by a layer of air or gas. The two panes of glass are sealed together around the edges, creating a space between them that is filled with either air or an insulating gas such as argon. This design provides improved thermal insulation compared to single-pane glass, as the trapped air or gas acts as a barrier to heat transfer. Double glazed glass is commonly used in windows and doors in residential and commercial buildings, as it can help to reduce energy costs by improving the building's energy efficiency. Additionally, double glazed glass can also help to reduce noise transmission and increase security
