How Our Manufacturing Process Supports NFRC Certification
Achieving NFRC certification starts with our high-quality manufacturing process. We use premium materials, advanced production techniques, and strict quality control to ensure every window and door meets the rigorous standards required for certification.
Our team meticulously tests each product for thermal performance, air leakage, and structural integrity before it leaves our facility. We also work with independent, third-party certification labs to verify that our products perform as advertised—ensuring you receive top-quality, energy-efficient products that meet or exceed industry standards.
What Is NFRC Certification?
The National Fenestration Rating Council (NFRC) is a nonprofit organization that provides independent, third-party ratings on the energy performance of windows, doors, and skylights. NFRC certification ensures products meet strict energy efficiency standards and provide accurate performance data on key metrics like U-factor, Solar Heat Gain Coefficient (SHGC), and Visible Transmittance (VT).
This certification helps consumers make informed decisions through a transparent, standardized rating system. When you see the NFRC label on a product, you know it has been independently verified for quality and performance.
