One Flushing, Queens, NY

As demand for ultra-high energy efficiency in the built environment grows, Crystal Window and Door Systems offers the perfect energy solution for new and renovated properties. As a proud long-term partner of Crystal Windows, REHAU uPVC window designs combine the structural performance of top aluminum with the extraordinary thermal performance of vinyl. Crystal Windows manufactures the MAGNUS 4500 Series, based on the REHAU System 4500 window design that features tight compression sealing frame and sash technology for superior energy efficiency, with glazing pockets that accommodate dual- and triple-pane insulating glass units. These architecturally rated, European-inspired products are ideal for select high-rise, multi-family, commercial, institutional, and upscale residential properties. Crystal MAGNUS 4500 windows have an outstanding AW-PG70 AAMA rating and can yield thermal U-values as low as 0.20.

One Flushing is a multi-generational affordable and senior housing development with 231 rental apartments, located in the heart of bustling Flushing, Queens near commuter rail lines.  The 10-story building with 400 feet of frontage covers much of an entire city block and features ground floor retail space. Crystal supplied over 1,500 MAGNUS 4500 Series In-Swing Casement and Fixed Windows with factory-installed PTAC louvers configured in master frames. While one building, the structure used a “sawtooth” offset facade and both light and dark grey textured face brick to break up the monolithic appearance and give the aesthetic illusion of multiple buildings. To achieve façade design and fenestration placement desired by the architects, Crystal custom designed and fabricated an innovative installation T-angle for the oversized windows.  

For sound attenuation and safety, Crystal sourced special insulated glass units from leading supplier Vitro Architectural Glass, with Solarban 60 low-E coating, Argon gas filling and laminated interior panes.  To accommodate senior residents and ADA compliance, Crystal placed handles for the operating windows at 44-46” above the floor and for families, Crystal provided 4” sash stop limiters in accordance with New York City multi-family building codes. Based on these discriminating fenestration systems, One Flushing wins US Glass Magazine’s Readers’ Choice Award 2019
