screen-vs-filmAbout the NFRC

NFRC is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products. Our goal is to provide fair, accurate, and reliable energy performance ratings so that:

  • Architects, builders, code officials, contractors, homeowners, and others can compare different products and make informed product choices.
  • Building officials, state government employees, and others involved in code development and enforcement can determine if products meet local codes.
  • Government- and utility-run energy efficiency programs can establish performance requirements and standards.
  • Manufacturers have a fair and level playing field to compare products and an accurate method of showing the


The National Fenestration Rating Council (NFRC) was formed in response to the energy crises of the 1970s.

To address concerns about energy consumption, the fenestration industry developed a host of new energy efficient technologies, including low-e coatings, low-conductance spacers, and gas fills.

Unfortunately, in advertising these new technologies some manufacturers made outlandish claims about the performance of their products. Consumers complained, and the federal government began to investigate.

By the late 1980s, industry stakeholders staved off confusion, federal intervention, and perhaps costly litigation by coming together in 1989 and founding NFRC to provide independent verification of product performance. Reed more about them at www.nfrc.org/about.aspx

Window Film or Solar Screens

Solar screen manufactures need to stop their spread of false heat reducing numbers. The public needs to be informed about the real statistics, the real numbers are public and easily found on the National Fenestration Rating Council’s website.

Window Film
You can find the ratings for all our products there on the NFRC site at www.nfrc.org but what you won’t find is anything on solar screens as they are not considered a viable product by the NFRC.

Solar Screens

HERE”S WHAT YOU SHOULD KNOW – The solar screen industry will show you heat reducing numbers that look incredible and that is because they are just that – uncreditable, these numbers have not been validated by the NFRC and are false.

Solar screens actually do cut 80 to 90 % of the visible light but what you see is not always what you get. Visible light is only 44% of the heat coming through your window. What you are left with after applying solar screens is 56% of that heat still coming through. 53% of the heat from infrared and 3% of the heat from ultraviolet light is still coming right through that window heating up your home.

Heat is not your only concern

The damage from fading can be costly and even devastating if we are talking about family heirlooms. You thought you were protecting your valuables by blocking the visible light using solar screens but again what you see is not always what you get.

Visible light only causes 25% of the damaging rays coming through a window. Ultraviolet light causes 40% of the fading as well as 25% caused by infrared light.

When using solar screens you are still allowing 65% of the damage that you were trying to avoid to continue.

Window Film

Window film actually cuts the infrared and ultraviolet light that solar screens do not. Take a look at the numbers from one of our films. The Prestige Series window film is one of the best window films manufactured by 3M. This film blocks 97% of the infrared light and 99.9% of the ultraviolet light and comes in a variety so you can choose how much visible light you want to block.

Don’t listen to the false clams being made by the solar screen industry; it will cost more in the end. Take a look at our site www.hometint.com and the ratings for our products on www.nfrc.org Make an informed decision before investing in any type of window coverings.
