Insulated glass, also known as double or triple glazing, consists of two or more glass panes separated by a space filled with air or gas. This design helps reduce heat transfer, making buildings more energy-efficient. The space between the panes acts as an insulator, minimizing noise and improving comfort. The glass is often sealed around the edges to prevent moisture from entering the space. Insulated glass is commonly used in windows and doors in residential and commercial buildings. It can also enhance security and reduce condensation, contributing to a more pleasant indoor environment.
