Triple-glazed windows consist of three layers of glass, separated by insulating gas-filled spaces. This design enhances energy efficiency by reducing heat loss and minimizing noise from outside. The additional layer of glass provides better insulation compared to single or double-glazed windows. These windows are particularly beneficial in extreme climates, as they help maintain a comfortable indoor temperature year-round. The use of argon or krypton gas between the panes further improves thermal performance. While they may be more expensive upfront, the long-term savings on energy bills can make them a worthwhile investment for homeowners.
