Reading the 3 NFRC Labels For Energy Efficient Windows

If you have been researching energy efficient replacement windows, you've probably come across the NFRC label. At this point, you aren't exactly sure what all those numbers mean, or what the label is even for. 

It is the only label that is accepted by the Energy Star® program to start with, and here is a simple guide to figuring it all out. The most important rule to remember when reviewing your NFRC labels is the lower the number, the better.
different kinds of energy efficient windows in Denver

1. Air Leakage

Your air leakage number is how much air per square foot goes through that particular window during testing. Your goal number here is a 0.1 which is the lowest. A 0.2 is good, and anything at a 0.3 is considered to be average. If you see a 0.4, you should pass.

2. Solar Heat Gain Coefficient 

This number is going to be between 0 and 1, and it tells you how much solar radiation gets through the window. In Denver, CO a 0.32 is ideal. The lower the number, the more you're going to save in the summer on air conditioning.

3. U-Factor

U-Factor is a measure of the heat that gets lost out the window. In our local area, that number should be a 0.30 or less. When you want extremely high-efficiency windows, try and purchase those with a rating of 0.25 or lower.
