Introduction to Insulated Glass
Insulated glass, also known as double – glazed or triple – glazed glass, is a type of glazing unit composed of two or more glass panes separated by a spacer and sealed around the edges. The space between the panes is filled with air or an inert gas such as argon or krypton. This design provides excellent thermal insulation, soundproofing, and condensation resistance. Insulated glass is widely used in residential and commercial buildings, automotive, and other industries to improve energy efficiency and comfort. Insulated Glass
