U.S.-based manufacturing alliance will deliver first-in-class, Passive House-quality window systems with unbeatable lead times and superior energy efficiency.

RAMSEY, N.J., Sept. 10, 2026 /PRNewswire-PRWeb/ -- Wythe Windows, a visionary manufacturer of high-performance tilt-turn windows and doors, today announced that it has been selected by high-end German manufacturer Schüco Polymer to become its UPVC window and door manufacturing partner in the U.S. The companies will officially debut the partnership at Build Show LIVE in San Antonio, Texas, on September 10-12.

This partnership will bring a first-in-class window and door system from Schüco Polymer to Wythe's leading fully automated manufacturing process to deliver the highest-quality product consistently and with unbeatable lead times. This merges Schüco Polymer's high European manufacturing standards with Wythe Windows' ethos and passion for introducing USA-made high-performance building products.

"Schüco's strength of high-quality engineering aligns perfectly with Wythe's excellent manufacturing capabilities," said Markus Herbst, CEO, Schüco Polymer Technologies KG. "This partnership ensures that more people will have access to the superior insulation and comfort that high-performance windows bring to the built environment."

Windows are a critical component of the building envelope, integrating all the layers into a single product. With a Wythe window designed in the Schüco UPVC system, buyers will have a window that delivers superior airtightness, watertightness, and insulation, collectively creating a more comfortable, affordable, and healthy home.

It's a major advancement for Passive House building standards, which can dramatically reduce heating and cooling loads by up to 90 percent. Wythe Windows and Schüco Polymer solutions are a critical part of Passive House's five basic principles, including an airtight building envelope, climate-appropriate insulation, thermal bridge-free design, balanced mechanical ventilation with heat recovery, and high-performance windows and doors.

"The partnership between Schüco Polymer and Wythe will elevate the Passive House construction manufacturing process by combining Schüco's precision-crafted UPVC profiles with Wythe's unmatched automation and commitment to USA-made high-performance building products," said Darren Macri, co‑CEO of Wythe Windows. "This partnership brings together groups of people who care about making the highest-performing windows and doors so that we can make the most number of people more healthy and comfortable in their homes."

"We are extremely proud that a company with Schüco's global reputation for engineering and quality has selected Wythe as a manufacturing partner here in the U.S.," said Rosario Vizzari, co‑CEO of Wythe Windows. "We believe it validates what we have been building for nearly a decade. Our goal has always been to take the best European window technology, manufacture it here, and adapt it to the way Americans design and build. Together with Schüco, we now have an incredible opportunity to bring that combination to a much larger U.S. market."
