National Fenestration Rating Council (NFRC) |
 |
Planning a little window shopping? Before you go, you'll want to know about this group. It has established an accepted, voluntary ratings system within the industry for the energy performance of windows, doors, and skylights. The ratings take into consideration a number of factors, including how well a particular model resists the transfer of heat, how much light it allows to pass through, and how much air leaks around the assembly. The NFRC label on certified products informs the consumer of these ratings. |
