Award-winning national manufacturer Crystal Window & Door Systems again expands its high-end window offerings with the introduction of the new aluminum outswing projected Series 8700 windows. 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.

“The slim sightline contemporary geometry of the Series 8700 windows represents the best in modern, sophisticated, environmentally sustainable window styling,” said Sabrina Leung, Architectural Sales and R&D Manager. “While European-inspired in design, the Crystal Series 8700 is proudly manufactured in America, with American materials, and by skilled American workers.”

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.

Test ratings for the Series 8700 windows are outstanding, with structural ratings of AW-PG100 for the outswing casement and fixed styles, and AW-PG85 for the awning style. With appropriate insulated glass packages, low U-values of 0.18 for the fixed style and 0.29 for operable styles can be achieved. These values surpass the requirements of New York City and other municipal and state energy codes. Additionally, using laminated glass options, the window line can attain acoustic performance ratings of STC 42 and OITC 34.

All three of the Crystal Series 8700 window styles come standard with 1” double glass insulated glass units (IGUs). A 1-¼” IGU option is available, as are triple glass, monolithic, and bird-deterring glass options. Low-E glass and argon gas are also available.

To achieve any desired design and complement a wide variety of façade materials, all the Crystal Series 8700 windows are finished in an array of standard and custom color sustainable powder coat paint, to AAMA 2604 (standard) or AAMA 2605 (upgrade) criteria. Other finishes are also available. In addition, the window’s polyamide strut thermal break readily facilitates two-tone (different interior and exterior) color schemes.

“Crystal offers many functionality and safety options for this new product line across all styles,” said Leung. “For example, units can be specified with opening limit devices, ADA compliant hardware, and between-the-glass grids, with a simulated divided light grid option to be introduced soon.”

The Crystal Series 8700 windows are compatible with the company’s full range of panning, receptors, subsills, and other installation accessories. To further facilitate installations, a 1.5” face fin (aka casement fin) frame is an option. Combinations of Series 8700 windows can be assembled using internal impost mullions and the common master frame option. Larger groupings or more complex arrangements of units can be combined using mullions, either factory- or field-assembled at the jobsite.

“The new Crystal Series 8700 window line was designed to provide architects and developers with versatile, stylish fenestration for today’s luxury properties,” said Leung. “Going beyond current codes, this window series offers energy and structural performance for long-term viability. It is a great choice for projects across the country.”
