The Series 8700 aluminum windows feature state-of-the-art polyamide strut thermal break technology, delivering enhanced energy efficiency.  Strength for the windows is improved through the use of heavy-duty extrusions and corner-keyed frames.  Visually, the minimal sightlines–2’ for fixed and 2-15⁄16” for operable windows–maximize vision glass, daylighting, and aesthetic appeal.  As such, the new Series 8700 line represents a step up in thermal efficiency, structural performance, and sightlines from the current Crystal Series 8500 window line. Available in casement, awning, and fixed styles, these new architectural windows excel in thermal performance and comply with the latest stringent energy code requirements of New York City and other jurisdictions.  With a 3-¼” jamb depth, the Crystal Series 8700 windows are suitable for both new construction and replacement applications involving mid-rise, high-rise, multi-family, office, hospitality, or institutional properties.
