The Woolworth Tower Residences completes window retrofit

offering sweeping views of New York City from historically inspired, new, high-performance windows

Wausau, Wisconsin – The iconic Woolworth Tower Residences’ top 30 floors have completed extensive renovations. Promising sweeping views of the city, each residence showcases new, historically inspired, high-performance windows and terrace doors from Wausau Window and Wall Systems. Linetec provided thermal improvement and finishing services for the windows and doors.

The 33 luxury condominiums at 2 Park Place range from one to four bedrooms with amenities including a private garage, fitness facility and 55-foot-long lap pool, plus wine storage for each unit and a tasting room. Residents have access to an exclusive entertainment lounge aptly named The Gilbert Lounge in honor of Cass Gilbert, the renowned architect who designed the building in 1913.

Guided by Developer Alchemy Properties, the architectural vision of SLCE Architects, LLP and The Office of Thierry W Despont, Ltd., the Woolworth Tower Residences’ interiors display Calacatta marble, Dada cabinetry, elevated ceilings and herringbone-patterned oak floors. The exteriors’ polychromatic terra cotta surrounds have been restored to their former grandeur. Wausau’s oversized windows make the connection between outside and in with breathtaking views.

Together with general contractor CNY Group and window contractor, Kilroy Architectural Windows, Inc., Wausau’s windows and terrace doors were confirmed as the best choice to maintain the prestigious property’s historic detailing, while delivering modern-day performance and easy operation.

Complementing the buildings’ historic aesthetic, Linetec finished the windows’ aluminum exteriors in a color called “Dark as Night” using a two-coat 70 percent PVDF resin-based coating. These durable painted coatings meet the American Architectural Manufacturers Association’s AAMA 2605 stringent standards, exhibiting industry-leading resistance to humidity, color change, chalk, gloss loss and chemicals. The resulting finish helps extend the window systems’ lifespan and reduces future maintenance.

Kilroy Executive Vice President Bill Kennedy added, “The building owner has stated, ‘Your windows at the Woolworth look BEAUTIFUL.’ It’s a huge difference!”

Working with the Apogee Building Retrofit Strategy Team, Wausau provided Kilroy with more than 630 units of 4250i INvent Series Simulated Double-Hung Projected windows, finished by Linetec, for the Woolworth Tower Residences.

“As their name indicates, simulated double-hung projected windows look like double-hung windows, but actually project from the plane of the wall, either inward or outward,” said Apogee Retrofit Strategy Team member Kevin Robbins. “Offset glass planes and narrow meeting rail profiles replicated the appearance of existing windows.”

In Spring 2016, Kilroy began the multi-phased, scheduled retrofit project on the Woolworth Tower Residences. Floor-by-floor, the team carefully removed the existing double-hung units. These had been manufactured using non-thermal framing and 1-inch insulating glass without the low-e coatings available today. After removing the previous unit, the rough opening was prepared using pre-assembled, extruded aluminum “panning” trim to help ensure the new Wausau window were easily installed plumb and square.

“The product performance and quality has been excellent, as we always expect from Wausau. The support from the Wausau team has been outstanding and critical in order to ensure a successful project,” praised Kilroy’s Kennedy.

Along with using low-e, insulating glass, Wausau relied on Linetec to provide polyamide thermal barriers within the aluminum frame of the windows and doors. Wausau INvent Series windows can achieve thermal performance NFRC U-Factors as low as 0.34, a Condensation Resistance Factor as high as 65 and acoustic performance Sound Transmission Class ratings of 31 to 42.

“The combination of these high-performance components – aided by the 4.5-inch-deep systems, as well as Wausau’s experienced engineering and quality fabrication – allow for minimal solar heat gain and better air infiltration performance, which supports energy efficiency and comfort,” explained Robbins.

He continued, “In addition to helping maintain the desired interior temperature, the windows and doors also reduce unwanted noise when closed. When the residents prefer to open their windows for natural ventilation, projected windows are easier to open than hung windows and eliminate balances, which require continual maintenance, especially in large sizes with heavy glass.”

Enduring appearance

The Woolworth Tower Residences’ new Wausau windows and terrace doors offer residents natural daylight and views of the cityscape from nearly every room, as well as the exterior terra cotta ornamentation surrounding the windows.

Robbins summarized the renovation project’s success saying, “Now completed, the windows on the Woolworth Tower Residences will provide improved thermal performance, which may be known only to the owner and occupants; while the windows’ visible contribution to the building’s historical look will remain evident to all.”

Facades+ features UW NanoES building with finishing by Linetec

UW_NanoES_ZGF-AaronLeitzPhotography9498-webThe University of Washington’s recently opened Nano Engineering and Sciences Building (UW NanoES) provides modern performance and visual continuity with the adjacent Molecular Engineering and Sciences Building (MolES). Demonstrating its energy-efficiency and daylight-focused design, the project is pursuing LEED® Silver certification through the U.S. Green Building Council.

The Seattle offices of Zimmer Gunsul Frasca Architects LLP (ZGF) designed the MolES building and sought to achieve the same aesthetic for the NanoES building. However, new, higher performance requirements in local building and energy codes meant that upgraded curtainwall and window systems were needed for the NanoES building.

UW_NanoES_ZGF-AaronLeitzPhotography261-webMeeting the project’s specified performance, unified appearance and durability, Linetec provided the finishing and thermal improvement services for Wausau Window and Wall Systems’ curtainwall and window systems, for Tubelite Inc.’s entrance systems, as well as for the shadow boxes, the sun shades and the accent fins. For the majority of these architectural aluminum products, Linetec applied a Silver Shadow color as a two-coat mica finish under stringent factory-controlled processes.
