     Energy Efficiency
In addition to the Series 7000 window line’s low U-values (see pages 48 and 49 for more information), a signature aluminum extrusion design utilizing custom Insulbar technology further reduces energy consumption. Windows are NFRC-tested and comply with California’s rigorous Title 24 requirements.
For strength against the elements, the Series 7000 casement, awning, and fixed windows received a performance rating of CW-PG50. A frame depth of 5.875” supports triple-pane, laminated, and security glass — essential options for noise reduction. The Series 7670 Casement, Series 7660 Awning, and Series 7675 Fixed Window are currently in testing for hurricane impact.
Cardinal Glass
The Series 7000 hinged window line offers performance glass options from Cardinal IG that 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.
Screens for the Series 7000 window line are manufactured from extruded aluminum for durability and are finished to match the window’s frame color.
Aluminum finishes are available in-stock or as designer selections. They can be customized to match nearly any color. For approximate finish options, see page 130. For exact paint swatch samples, contact us.
