Insulating glass improves the quality of Simonton windows and doors by: How does insulating glass improve the quality of Simonton’s windows and doors?Ī. Because of its density, it’s used to replace air between the glass panes to reduce temperature transfer for better thermal efficiency. 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.Īrgon Gas is an odorless, colorless, tasteless, non-toxic gas that is six times denser than air. What is Low E/Argon-filled glass, and how does it help improve energy efficiency?Ī.

When shopping for windows or doors, look for higher R-values and lower U-values for the most energy-efficient products possible. The lower the U-value, the better the insulating quality. U-value is the amount of heat transferred through a material. The higher the R-value, the better the resistance. R-value is the resistance a material has to heat flow. What are R-values and U-values, and why does it matter?Ī. Just choose the ENERGY STAR glass package based on your region’s climate zone. Simonton has taken the guesswork out of choosing energy-efficient glass packages that meet ENERGY STAR guidelines. Which options do I select for my windows and doors to meet ENERGY STAR guidelines?Ī. Only windows and doors that meet strict criteria set forth by the EPA are ENERGY STAR-qualified. An ENERGY STAR rating is your assurance that windows and doors will deliver effective thermal performance in your climate zone. How do I determine which windows and doors are energy-efficient?Ī.
