Installing new windows can dress your home up to give it a new look while also improving your home's energy efficiency. When choosing Jeld-Wen vinyl windows, be sure you know and understand the U-factor of whichever vinyl window option you consider.

What is the U-Factor?

The U-Factor rating was created by the National Fenestration Rating Council (NFRC) and is recognized nationally by window manufacturers, builders and homeowners. It is the rate at which a window, door, or skylight conducts non-solar heat flow. For windows, skylights, and glass doors, a U-factor may refer to just the glass or jeld-wen vinyl windows offer beauty and U-Factor efficiencyglazing alone. NFRC U-factor ratings, however, represent the entire window performance, including frame and spacer material. The lower the U-factor, the more energy-efficient the window, door, or skylight.

This rating is assigned by the manufacturer of a window to indicate the rate of heat that is lost from the home via the window. The U-Factor is not to be confused with the center-of-glass-U-Factor, which is a rating of only the glazing of the window.
