The film comes first
Kepler builds its name on the film itself. Each range is developed for optical clarity, color stability and consistent solar performance, then supported by technical data and digital tools that make choosing a shade clearer rather than more confusing. Visible light transmission is simply the amount of light passing through the glass; heat performance is measured separately, so a darker film is not automatically the cooler one. Compare the exact film and shade you have in mind, and use a dealer to talk it through before anything goes near your windows.
