Wythe Windows, a manufacturer of high-performance tilt-turn windows and doors, announced it will showcase its advanced automated aluminum platform and high‑performance retrofit systems at the New York Build Expo construction and design show. The company's next‑generation aluminum and retrofit products aim to eliminate the green premium often associated with energy‑efficient building upgrades, delivering industry‑leading Passive House performance with lead times and price points that make high‑performance buildings accessible.

Why it matters

Wythe Windows' products are designed to help address the challenge of decarbonizing existing building stock, especially occupied multifamily buildings, which is a critical and complex issue facing cities. The company's precision-engineered solutions allow for the modernization of aging buildings without requiring residents to relocate, lowering energy costs and consumption without undercutting quality or affordability.

The details

Wythe Windows' latest products produce robust aluminum systems with deep thermal breaks engineered to meet rigorous energy standards, while maintaining the clean, modern profiles that architects expect. The company's overcladding retrofit wall panel 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 their existing building with a precision-engineered new skin to achieve Passive House performance without requiring residents to relocate.

  • Wythe Windows will showcase its products at the New York Build Expo on March 18–19, 2026.
  • The company's overcladding product has cleared feasibility assessments and entered the production and go-to-market phase, with initial support from two NYSERDA grants, PON 6 and PON 7, under the NextGen program.
