 My name is Tom Herron with the National Fenestration Rating Council. I know fenestration is not a word that you hear every single day, but simply put it refers to windows, doors, and skylights. One of the main things that NFRC does is empower consumers who are the market for energy-efficient windows. They can come to us to get the objective, unbiased information they need to compare products before they make a purchase. Well, the most important benefit is that it provides a layer of protection to consumers. So when they go out into the marketplace, they can compare products before they make a purchase. In our ratings and labeling system, most manufacturers accountable for the energy performance claims that they're making.
