Soho House saved as much original material as they could including the brick, the columns and even the lettering above the front door. Working with the Apogee Building Retrofit Team, it was determined the existing steel windows were beyond repair and nearly 500 new units from Apogee’s Wausau Window and Wall Systems would be installed to help maintain the historical detailing, while delivering modern-day performance.
As the window erection contractor, Auburn Corp. worked closely with Wausau Window and Wall Systems. Wausau’s team also was supported by the building retrofit strategy leaders at its parent company, Apogee Enterprises Inc.
“Improving the appearance of the building is one reason owners decide to upgrade their window systems. This is even more critical for historic buildings,” emphasizes John Bendt, vice president at Apogee Enterprises. “It doesn’t need to be a 100 year-old building to understand that carefully selecting the right window system will lead to other benefits. Most of our commercial buildings in the U.S. are at least 40 years old, and all can benefit from saving energy, reducing maintenance, lowering vacancy rates, increasing rents and increasing the value of the building.”
Jeffrey Shapack, president of Shapack Partners, agrees, “The historic window replacement was essential to maintaining the appearance of our 1900’s warehouse building, both on the exterior and on the interior. Apogee’s Building Retrofit Strategy Team and Wausau helped us select a window that would match the large scale and fine detail of this type of property.”
“There was a certain design they were looking for in maintaining this old factory look. The large openings and replicating the steel windows were an important part of this,” notes Auburn’s manager of business development, Jim Price. “Wausau’s windows were selected to retain the look of a vintage building, while providing the latest innovations in window technology.”
Customized for Soho House Chicago, Wausau’s 3250i INvent Retro XLT Series historical windows simulate the look of original, turn-of-the-century steel windows’ true divided lites with a narrow, exterior face in cove profiles. The 3-7/8-inch aluminum frame pairs with custom panning and muntins applied to both interior and exterior to complete the aesthetic.
“The owner was meticulous about ensuring these windows mimicked the authenticity of the old steel windows,” notes Terry Iczkowski, Wausau’s local representative. “Beyond the narrow profiles and muntins, they wanted the finish to communicate a sense of longevity and timelessness. Apogee’s Linetec helped achieve the slightly distressed appearance that the owner desired by applying a matte Statuary Bronze finish.”
Linetec blended the 70 percent PVDF, two-coat painted finish at its in-house laboratory and applied it within its factory-controlled environment to the windows’ aluminum framing, panning and muntins. Linetec also finished the aluminum framing for the glazing systems on Soho House Chicago’s 144-foot perimeter rooftop pool. Provided by Wausau and installed by Auburn, the transparent pool enclosure presents unobstructed views of Chicago’s skyline.
Working from the ground floor upward for more than a year, Auburn’s team synchronized their work with the general contractor and other specialty contractors. Floor-by-floor, the large openings were prepared for hundreds of new windows. There are multiple windows per opening, with some individual window dimensions larger than 4.5-by-9.5-feet, grouped to up to five per bay. On average, six people were on site to assist with the installation of these units.
Along with providing views and daylight, Wausau’s windows also meet Chicago’s energy codes. INvent Retro XLT windows feature double insulating glass and an extra-wide polyamide thermal barrier to achieve a U-Factor as low as 0.39 BTU/hr.sqft.F and a Condensation Resistance Factor (CRF) as high as CRF Frame 60/CRF Glass 70.
These windows also are tested to meet AAMA AW100 Architectural Performance Class ratings, including AAMA 910-10 lifecycle testing to 4,000 operating cycles and requirements for air infiltration, water resistance, life cycle testing and structural integrity. INvent Retro Series windows are part of the pre-engineered, factory-glazed Advantage by Wausau standard product offering. Available on an accelerated delivery schedule, these windows are backed with a warranty of up to 10 years.
“Wausau’s windows worked so well and look so good that we’ve received several calls for other potential renovation projects,” adds Price. Across the city on Polk Street, Auburn’s team is replacing the windows at the University of Illinois’ College of Medicine’s West Tower with Wausau’s INvent Retro Series. “Wausau’s windows are a great match for the historic appearance and high thermal performance required by these buildings.”
Shapack summarizes, “The INvent Retro-XLT windows provide the daylight, performance and attention to detail that we needed. And Apogee, Wausau and Auburn met our schedule to ensure an on-time opening.”
