Argon is odorless, colorless, non-toxic, and widely available. That makes argon filled glass a practical, value-forward choice for most homes. It has lower thermal conductivity than air, so it slows the movement of heat through the glass unit. In winter, argon filled windows help keep warm air inside. In summer, they reduce heat gain, helping your cooling system work less. The result is a more stable indoor temperature and fewer uncomfortable hot or cold spots near windows.
For Kentucky's climate, argon-filled glass delivers excellent performance without the premium price tag, especially when matched with modern low-E coatings and quality frames.
Renewal by Andersen replacement windows and argon glass are engineered as a complete solution: durable frames, precision spacers, advanced low-E coatings, and argon fill all working together. Those layers work together to manage heat flow, reduce glare, and block a significant portion of UV rays, all while preserving clear views and natural light.
Every home is different. Renewal by Andersen offers replacement windows and argon glass packages to fit your goals. Choose from double-hung, casement, gliding, picture, awning, bay/bow, or a combination, each available with argon filled glass and multiple low-E options.
