Cielo
COMMERCIAL : SNAPSHOTS: GREAT GLAZING

Cielo, meaning sky in Spanish, is a fitting name for New York City developer JD Carlisle’s new luxury condominium in Manhattan. Located in the Upper East Side, the 27-story building soars above the neighboring structures and offers “beautiful views” to residents through their floor-to-ceiling windows, says Peter Fuchs, project manager for Wausau Window and Wall Systems of Wausau, Wis.
“This is not a very tall area; there aren’t many buildings above 10 stories,” Fuchs says. “[The architect and developer] were trying to make this building be among the clouds. With all the glass, it definitely will make it feel like that.”
Perkins Eastman Architects PC of New York City designed the 245,000-square-foot structure with 128 luxury condominium units, a 2,000-square-foot exercise center, 4,000 square feet of medical office space and underground parking. The studio, one-, two- and three-bedroom units, with 10-to-11-foot ceiling heights, range from $700,000 to $5 million. The units measure between 626 to 3,221 square feet.
Wausau supplied its 4250iV Visuline windows, which provide more than vistas of the Manhattan skyline and the East River, Fuchs says. The windows also offer high comfort levels and energy efficiency, despite their large size.
“We had to meet New York City energy codes and a tough zero visible condensation test,” Fuchs says. “We had to beef up [the Visuline series] a little bit.”
To improve the performance, Wausau adjusted some frame sizes, added poly butyl chloride thermal wrap on the sash and used warm edge spacers in some areas, Fuchs says. The windows feature 1-inch insulating, low-emissivity glass.
Emily Kelly, project manager and senior associate from Perkins Eastman Architects says they chose the windows primarily because of their high performance, “so we could use as much glazing as possible.” In addition, “We used the system because it has the equal sightlines, so you don’t see where the windows are,” she says. “It’s very sleek.”
American Industries Corp. of New York City was the glazing contractor and MD Carlisle Construction Corp., a sister company of the developer, also of New York City, served as the general contractor.
The building opened to residents last month. The cost is undisclosed.
