Foshan AMJ Windows and Doors Co., Ltd. 
At AMJ, we don't just claim energy efficiency—we prove it. These documents showcase our NFRC (National Fenestration Rating Council) compliance through rigorous thermal simulation and physical labeling. Each window system undergoes advanced computer modeling to calculate precise U-Factor, SHGC (Solar Heat Gain Coefficient), and Visible Transmittance values.
Technical Highlights:
NFRC Labeling: Every unit delivered to the North American market comes with a verified NFRC temporary label, allowing site inspectors and homeowners to confirm energy code compliance instantly.
Thermal Simulation Mastery: Our engineering team utilizes industry-standard software to optimize the thermal break design and glazing configurations, as shown in the infrared-style simulation report.
Data-Driven Performance: By analyzing heat flow patterns through the frame and glass, we achieve industry-leading insulation values that meet and exceed Energy Star requirements in various climate zones.
