The Film Comes First
Everything starts with the film itself. Kepler IR and IR+ are nano-ceramic automotive ranges built to manage solar heat and glare while keeping the view out of the vehicle clear, and the architectural side covers solar control, privacy, safety and security work on buildings. Performance varies between products, so it is worth comparing the exact film and shade rather than judging by darkness alone. Visible light transmission describes how much light passes through the glass; how a film handles solar heat is a separate question, and two films at the same shade can behave very differently in the sun.
