Energy Efficiency Questions

Q. How do I determine which windows and doors are energy-efficient?

A. An ENERGY STAR rating is your assurance that windows and doors will deliver effective thermal performance in your climate zone. Only windows and doors that meet strict criteria set forth by the EPA are ENERGY STAR-qualified.

Q. Which options do I select for my windows and doors to meet ENERGY STAR guidelines?

A. Simonton has taken the guesswork out of choosing energy-efficient glass packages that meet ENERGY STAR guidelines. Just choose the ENERGY STAR glass package based on your region’s climate zone. It’s that simple!

Q. What are R-values and U-values, and why does it matter?

A. R-value is the resistance a material has to heat flow. The higher the R-value, the better the resistance. U-value is the amount of heat transferred through a material. The lower the U-value, the better the insulating quality. When shopping for windows or doors, look for higher R-values and lower U-values for the most energy-efficient products possible.

Q. What is Low E/Argon-filled glass, and how does it help improve energy efficiency?

A. Low E (Emissivity) glass has a special surface coating that allows short-wave energy to pass through but reflects long-wave infrared energy, improving the U-Value.

Argon Gas is an odorless, colorless, tasteless, non-toxic gas that is six times denser than air. Because of its density, it’s used to replace air between the glass panes to reduce temperature transfer for better thermal efficiency.

Q. How does insulating glass improve the quality of Simonton's windows and doors?

A. Insulating glass improves the quality of Simonton windows and doors by:

  • Improving the performance of the U- and R-values of your new windows and doors.

  • Reducing condensation.

  • Helping keep the heat in and cold out during winter.

  • Helping keep the heat out and the cold in during summer.

Q. When it comes to energy efficiency, how do vinyl windows compare with windows made from other materials, such as wood and aluminum?

A. The premium vinyl used in Simonton’s windows and doors is inherently and excellent insulator. It’s far superior to aluminum, and comparable to most wood products. But unlike other materials, vinyl requires virtually no maintenance.
