QUEENS, NY, April 24, 2025 – National manufacturer Crystal Window & Door Systems recently completed supplying over 2,500 energy efficient windows and doors for a large modern new mixed use residential development in Nashville, TN.  Crystal supplied state-of-the-art commercial uPVC vinyl tilt-and-turn and fixed windows as well as uPVC swing terrace and sliding patio doors. Located at 622 Merritt Avenue, The Finery totals 415,000-ft2 and consists of 3 distinct 5- and 6-story buildings plus an adjoining parking garage.  The buildings are interconnected by upper floor crossover bridges and at ground level by an open-air pedestrian plaza.  The buildings maintain their individual modern post-industrial characters through the use of three very different façade styles – colorful corrugated metal, diagonally seamed metal panels, and traditional dark brick.  The buildings’ apartments offer numerous balconies extending from the facades. Unplasticized polyvinyl chloride or uPVC has been a common window and door frame material in Europe for decades.  Now uPVC is growing in popularity in America since it offers strength similar to aluminum frames with the superior thermal efficiency and sound attenuation of traditional vinyl windows. “As one of the national leaders in uPVC window fabrication, Crystal is seeing increasing demand for our MAGNUS commercial uPVC windows in all types of mid- and high-rise projects, as they provide exceptional comfort for residents of multifamily properties,” said Papo Perez, Crystal Branch Manager and project leader for The Finery.  “It is great to have owners, GCs, and architects in Nashville and in all major markets across the country embrace this superior fenestration material.” The Finery project relied heavily on the Crystal MAGNUS 4500 dual action tilt-and-turn and fixed picture windows.  Over 2,100 of these operating and fixed window panels were used to fill 817 building openings, mostly in large floor-to-ceiling combinations.  In a few openings, a large 9-panel fixed arrangement spanned an opening 132” wide by 96” tall. The Crystal MAGNUS 4500 dual action tilt-and-turn window offers both in-swing casement and tilt-in at the top operations.  This uPVC window is rated CW-PG95/AW-PG70 and for this project was thermally rated at U=0.29.  The MAGNUS 4500 features multi-point locks, top quality European-styled hardware, sash perimeter compression seal technology, and opening limit safety devices.  The Crystal MAGNUS fixed window is also rated AW-PG70.  Both styles were specified with the 3-¼” frame option. For access to balconies and terraces, the Nashville residential development used 344 Crystal MAGNUS 4500 uPVC swing doors and 44 Crystal MAGNUS 2150 uPVC sliding doors.  The Crystal MAGNUS 4500 terrace door features a 3-¼” jamb depth, strong multi-chamber reinforced frame and sash, compression seals, multi-point locking and 3’ x 8’ custom sizing.  A number of the Crystal swing doors were combined with large adjoining windows to create expansive multiple units, some up to 140” in width.  Many of the Crystal MAGNUS 4500 out-swing terrace doors for ADA compliant apartments were specified with a low sill option.  The out-swing door is rated LC-PG80. The Crystal MAGNUS 2150 uPVC 2-panel sliding doors have a 4-9∕16” jamb depth and feature a durable locking handle and dual steel rollers for easy operation.  The custom sized sliding doors ranged in width from 72” to 96”.  Some sliding doors were combined with adjoining side and transom windows to span even larger openings for grander views. All the Crystal windows and doors on The Finery buildings used 1” dual-pane insulated glass units (IGUs).  To enhance thermal performance, Vitro Solarban 60 low-E glass with argon gas filling was specified.  Where required by code or safety, tempered glass was used.
