Crystal Windows supplies Manhattan project

Crystal Window & Door Systems recently supplied over 2,600 energy-efficient replacement aluminum windows for the 40-story Knickerbocker Plaza rental apartment complex. Located at 1751 Second Ave. on Manhattan's Upper East Side, the building has undergone a major energy efficiency "weatherization" upgrade, which in addition to new windows includes lighting improvements and new Energy Star appliances. One of New York's premier window installation and weatherization contractors, ASK Construction of Astoria, N.Y., performed the fenestration work. "Crystal is a preeminent supplier of modern, energy efficient windows for weatherization projects in the New York City area and throughout the nation," said Vincent Grieco, Crystal's New York regional sales manager. "Our broad product line of aluminum and vinyl windows, superior thermal performance, appealing features and options, and competitive pricing make Crystal Windows an easy choice for architects, energy services firms, government funding agencies, and property managers and owners involved with weatherization and efficiency upgrade projects." Crystal supplied almost 2,200 Series 6000 aluminum double-hung windows for Knickerbocker Plaza's apartments. Over 200 Series 8100 aluminum picture windows and more than 200 Series 8200 aluminum project-out windows were installed in a stacked configuration in hallway areas.
