Purchasing windows, doors, and skylights is a significant investment and complex purchase decision. Homeowners want the right windows for their home, but few know what to look when shopping around for products.

 

The National Fenestration Rating Council (NFRC) is an independent non-profit organization that establishes objective window, door, and skylight energy performance ratings to help you compare products and make informed purchase decisions in the following ways:

 

●        Communicating the energy performance of products using the NFRC label

●        Helping you understand the different categories of energy performance

●        Providing tips, tools, and educational resources

●        Narrowing your product search through our NFRC Certified Product Directory

●        Delivering friendly, expert support

 

NFRC-certified products are independently tested, certified, and labeled to help you make the best purchase decision for your needs.

What is the Difference Between NFRC and ENERGY STAR?

Energy Star is a government-backed labeling program that helps people and organizations save money and reduce greenhouse gas emissions by identifying factories, office equipment, home appliances and electronics that have superior energy efficiency.

 

While the ENERGY STAR label tells you if a product is energy-efficient, the NFRC label helps you compare energy-efficient products by breaking down a product’s energy performance. Therefore, you get a more detailed analysis of a product.

What does the NFRC Label Tell You?

The NFRC label helps you compare between energy-efficient windows by providing you with energy performance ratings for windows.

 

What information does the label contain?

U-Factor

U-Factor measures how well a product can keep heat from escaping from the inside of a room. The lower the number, the better a product is at keeping heat in.

Solar Heat Gain Coefficient

Solar Heat Gain Coefficient measures how well a product can resist unwanted heat gain, which is especially important during summer cooling season. The lower the number, the less you’ll spend on cooling.

Visible Transmittance

Visible Transmittance measures how well a product is designed to adequately light your home with daylight, potentially saving you money on artificial lighting. The higher the number, the more natural light is let in.

Air Leakage

Air leakage (or air infiltration) is the measurement of how much air passes through the window assembly. The number is calculated before the installation to ensure that it is accurate upon installation. Air leakage is measured on a scale of 0.1-0.3 with 0.1 being the least amount of air that passes through the window. The NFRC is responsible for determining the standards for the rating.

How the NFRC Rating Benefits You

The short answer is it can help you choose the right products for your home. Specifically, the NFRC rating helps you the following ways:

 

●        Understand how window insulation works

●        Discover which insulating properties have the highest quality

●        Learn the basics of heat transfer in and out of the home

●        Find the connection between quality windows and energy costs

●        Find which windows require the lowest maintenance
