As energy efficiency standards continue to rise across the North American construction market, certified performance has become a key requirement for architects, developers, contractors, and homeowners when selecting window and door systems.

Topbright is proud to announce that three of our core aluminum systems have successfully completed NFRC testing and obtained official certification:

• TOP65 Casement Door

• TOP100 Casement Window

• TOP108 Sliding Window

These certifications further demonstrate our commitment to delivering high-performance, energy-efficient aluminum window and door solutions for residential and commercial projects across the United States and Canada.

What Is NFRC Certification?

The National Fenestration Rating Council (NFRC) is the leading organization in North America responsible for evaluating and certifying the energy performance of windows, doors, and skylights.

NFRC-certified products are independently tested for key thermal performance indicators, including:· U-Factor

• Solar Heat Gain Coefficient (SHGC)

• Visible Transmittance (VT)

• Air Leakage (AL)

• Condensation Resistance (CR)

For builders and project developers, NFRC certification provides verified performance data that supports:

• ENERGY STAR compliance

• Building code approval

• LEED and green building projects

• Energy-efficient residential and commercial developments
