NFRC (National Fenestration Rating Council)

The National Fenestration Rating Council (NFRC) is an organization that provides standardized ratings for windows, doors, and skylights, helping consumers and professionals compare energy efficiency and performance qualities. These ratings include factors like insulation (U-factor), solar heat gain (SHGC), and visible light transmittance (VT), offering transparent, reliable information. NFRC certification ensures products meet specific energy standards, aiding informed decision-making for energy-efficient, sustainable, and cost-effective building choices. This helps homeowners, builders, and architects select fenestration products that optimize comfort, reduce energy bills, and improve overall building performance.
