In 2005 the National Fenestration Rating Council adopted a new rating label to inform customers on the energy performance of a product.
You can find these labels on your new windows but what they represent is often difficult to decipher. But note, manufactures are not required to use them. I suggest you stick with manufacture that participate to guarantee the level of efficiency you need.
I'm going to give an overview on 4 of the NFRC ratings and what that means regarding performance.

Thanks for the heads up! We at Window Planet make sure to have this on each new window we installed.
