Insulated windows are specially designed to reduce heat transfer between the inside and outside of a building. They typically consist of two or more glass panes separated by a space filled with air or gas, such as argon or krypton. This design helps to keep homes warmer in the winter and cooler in the summer, improving energy efficiency. In addition to energy savings, insulated windows can also help reduce noise from outside, making indoor spaces quieter. They are often used in residential and commercial buildings and can be customized with various coatings and frame materials to enhance performance and aesthetics.
