Research Frontiers and Advanced Impact Technologies Group announced Thermolite RetroWAL on October 27, 2025. They described an SPD-SmartGlass retrofit system developed with Gauzy, which produces the light-control film.
The companies said the system could add adjustable shading without removing a building’s original glazing. That installation concept is an attributed product claim; TintNews has not independently verified its performance.
The release scheduled a demonstration at GlassBuild America in Orlando for November 4–6, 2025. The preview does not establish that the demonstration occurred. Current availability, completed installations and energy savings were not verified.
