Each year, the average American household spends $1,500–2,500 on energy bills.
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 is committed to advancing continuous improvement of windows, doors, and skylights, contributing to making buildings more comfortable and energy efficient.
What is fenestration, anyway?
Fenestration refers to all things related to windows, doors, and skylights. It originated from the Latin word “fenestra,” meaning “opening.”
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.
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.
