45% of that cost is for heating and cooling. Choosing high-performance windows, doors, and skylights can save you money and keep your home comfortable.

The National Fenestration Rating Council (NFRC) is committed to advancing continuous improvement of windows, doors, and skylights, contributing to making buildings more comfortable and energy efficient.
NFRC empowers consumers to make informed choices about their home’s energy efficiency. The NFRC label provides clear, factual ratings across key performance categories.
What does the NFRC label tell you?
The NFRC label helps you compare between energy-efficient windows, doors, and skylights by providing you with energy performance ratings in multiple categories.
NFRC also has a condensation rating that is optional for manufacturers to include, so you may or may not see it on the label. The higher the number, the better a product resists condensation. Download the optional label.
How is the NFRC label different than the ENERGY STAR label?
Think of it this way: the ENERGY STAR label tells you that a product is energy-efficient. The NFRC helps you compare between energy-efficient products by giving you independent ratings in several energy performance categories.
