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 glass panes is filled with air or an inert gas such as argon or krypton. This design significantly enhances the thermal insulation, sound insulation, and condensation resistance properties of the glass. As a result, insulated glass is widely used in the construction industry for windows, doors, curtain walls, and other building envelopes, helping to improve energy efficiency and indoor comfort.
