Smart film isn’t a roll you trim on the glass like standard tint — each panel carries electrical connections and has to arrive sized to its exact opening. Twenty-one windows meant twenty-one measurements, twenty-one custom-cut panels, and twenty-one wiring runs back to the switching controls. It’s the least forgiving install we do, which is why we handle every step ourselves rather than farming it out.
By Gauzy’s published specs for this film class, the panels switch from clear to opaque in under 0.1 seconds and read at roughly 2.5% haze in clear mode — so between patients the glass looks like ordinary storefront glass, not a milky privacy film. Values vary by product line and drive voltage; we confirm against the current data sheet on every job rather than quoting from memory.
