What Does it mean if Windows are Rated by the National Fenestration Rating Council (NFRC)?
The National Fenestration Rating Council (NFRC) is an American non-profit organization that sponsors an energy efficiency certification and labeling program for windows, doors, and skylights. While an ENERGY STAR certification denotes that a particular window or door is considered to be “energy efficient” in a general sense, the NFRC provides more specific information in five performance categories, including:
- U-value – the rate of the transfer of heat through the window or door unit
- Solar Heat Gain Coefficient (SHGC) – the amount of solar heat a unit transmits
- Visible transmittance – the fraction of the visible light spectrum that a window transmits
- Air leakage – the measure of air infiltration through a window or door
- Condensation resistance – how well a window resists the formation of condensation
With these specific, detailed measurements of performance, homeowners and builders alike are better able to compare different brands of replacement windows and doors to determine which products might work best for their homes or the homes of their customers.
