Q: WHAT IS THE BEST WAY TO COMPARE WINDOWS?

Examining the NFRC rating is the most dependable method to evaluate different windows. This rating includes the U-Factor and Solar Heat Gain Coefficient (SHGC), which are essential indicators of a window’s overall performance and are validated independently. Lower ratings signify superior performance. 

Since the preference between U-Factor and SHGC depends on your specific climatic conditions, choose NFRC ratings that align with both your environmental and budgetary needs, ignoring any sales hype.

Q: What is an Energy Star window?

Due to the federal government’s sponsorship of the ENERGY STAR® window certification program, selecting windows that are optimized for energy efficiency and adaptability to various climate conditions is possible. To qualify, windows need to meet or exceed the standards outlined below. These criteria, grounded in all NFRC’s performance ratings, vary according to different climate zones.

  • Northern Zone (blue): U-Factor of .30 or less, SHGC any
  • North Central Zone (yellow): U-Factor of .32 or less, SHGC of .40 or less
  • South Central Zone (orange): U-Factor of .35 or less, SHGC of .30 or less
  • Southern Zone (red): U-Factor of .60 or less, SHGC of .27 or less
