Wythe Windows Showcases Aluminum Windows and Retrofit Solutions

Wythe Windows, a manufacturer of high-performance tilt-turn windows and doors, announced it will showcase its automated aluminum platform and high‑performance retrofit systems at March trade shows, including Fensterbau Frontale in Germany.

The company’s next‑generation aluminum and retrofit products delivering Passive House performance with lead times and price points that make high‑performance buildings accessible, from luxury urban lofts to large‑scale affordable housing.

Wythe Windows’ latest products produce aluminum systems with deep thermal breaks engineered to meet rigorous energy standards, while maintaining clean, modern profiles that architects expect in urban projects.

The product complements Wythe Windows’ overcladding retrofit wall panel, an envelope‑in‑a‑box solution that functions as a high‑performance jacket for aging buildings, wrapping them in a new thermal envelope with windows pre‑installed and finishes factory‑applied. 

This allows building owners or developers to retrofit existing buildings with a precision-engineered new skin to achieve Passive House performance without requiring residents to relocate.

“The challenge of decarbonizing our existing building stock, especially occupied multifamily buildings, is one of the most critical and complex challenges facing our cities,” says Darren Macri, Co‑CEO of Wythe Windows. “Our latest products make it possible to modernize aging buildings with precision‑engineered solutions that lower energy costs and consumption without undercutting quality or affordability.”

NYSERDA-Backed retrofits

Wythe Windows’ overcladding product, initially supported by two grants, PON 6 and PON 7, awarded under the New York State Energy Research and Development Authority’s NextGen program, has cleared feasibility assessments and entered the production and go-to-market phase. 

The aluminum window line and the retrofit system are directly linked: the same automated production infrastructure that manufactures the new aluminum fenestration also produces the precision-engineered framework at the heart of the overcladding panel. By running both NYSERDA grants concurrently, Wythe Windows has compressed what is typically a multi-year innovation timeline to rapidly bring this technology to market.

“We’ve proved product viability, demonstrating that a unitized, overcladding solution for urban multifamily buildings is technically viable,” says Macri. “Now, our focus is bringing this technology directly to New York streets at scale, rapidly modernizing our aging building stock with a precision-engineered 'new skin' that is built for the realities of the city and can be installed without displacing a single resident.”

Comfort, wellness and environmental benefits 

Wythe Windows’ latest announcement comes as builders, home buyers and residents face rising demand for sustainable high‑performance housing solutions. The benefits include:

• Quality of Life: Wythe’s Passive House windows feature multi-point locking systems and triple-gasket seals, creating an airtight, acoustic barrier. For families living adjacent to elevated highways or transit lines, that translates into quieter apartments. 
• Environmental Impact: Wythe’s airtight systems keep outdoor pollutants from penetrating living spaces. The insulative frames not only make the home more comfortable but they also eliminate the risk of condensation that feeds mold that can be seen on drywall or be hidden behind it.
• Future Proofing: The company is also introducing an Integrated Heat Pump Window, which nests a high-performance HVAC system directly into the window itself. Building owners can replace aging heating and cooling infrastructure in a single installation step, without major interior renovation.

“Visitors will also be able to experience our high performance UPVC windows. Our automated production lines for this style were custom built to provide exceptional lead times with consistent quality. Our tilt turn windows are AW60 rated - which means that this window meets some of the most air, water and structural performance along with its leading Passive House level thermal performance,” says Macri.
