      Energy Efficiency
Energy-smart in a variety of weather conditions, the Series 7900 features a .30 U-value for standard low-E, argon-filled dual-pane glass, and a .21 U-value for high-performance triple- pane glass. Our signature aluminum extrusion design further reduces energy consumption. The Series 7900 is compliant with California’s rigorous Title 24 requirements.
Size and Strength
Currently available in 4’ x 12’ panel sizes,
the Series 7900 Hinged Door is performance- rated at DP50 (inswing) and DP50 (outswing). Available in single or double inswing and outswing configurations.
Cardinal Glass
The Series 7900 Hinged Door comes standard with Cardinal IG’s all- climate coated or high-performance glass, which provides solar control and high visibility. Glass can be customized in a variety of types, colors, and thicknesses. Options include laminated glass, solar- and glare-control glass, enhanced winter performance glass, and Neat low-maintenance glass. Pre-applied Cardinal Preserve film protects glass during installation.
Smooth Operation and Hardware
Available with the medium stile, an optional concealed overhead closure and secondary lock ensure the door is self-closing. On doors over 96” tall, stainless steel roller catches are utilized to help pull the door in tight.
For even more design flexibility, the Series 7900 Hinged Door can be combined with our fixed and hinged windows.
