Government energy performance labeling is designed to help the consumer. But, we admit – it can be confusing. At Window Innovations a big part of our motto is Hassle-Free. So, we are here to answer your questions further.

What makes it ENERGY STAR?

ENERGY STAR qualified, windows, doors, and skylights:

1. Are manufactured by an ENERGY STAR partner,
2. Are independently tested, certified, and verified by the National Fenestration Rating Council (NFRC), and
3. Have NFRC ratings that meet strict energy efficiency guidelines set by the US Environmental Protection Agency (EPA).

Though ENERGY STAR does not require any specific technologies, certain product features are common in many certified products.

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.

Independent energy ratings.

Informed purchase decisions.

NFRC-certified products are independently tested, certified, and labeled to help you make the best purchase decision for your needs. While the ENERGY STAR label tells you if a product is energy-efficient, the NFRC label helps you compare between energy-efficient products by breaking down a product’s energy performance.

What does the NFRC label tell you?

The NFRC label helps you compare between energy-efficient windows, and doors by providing you with energy performance ratings in multiple categories. Take a moment to learn more:
