Window tinting in Iowa
Iowa front doors stay nearly clear. Heat rejection on those panes has to be ceramic, not a dark dye.
In Iowa, front side windows must let at least 70% of visible light through. Rear glass can be any darkness. Windshield film stays a clear strip at the top, not a full tint. House and storefront film is not held to that driving rule. This is a summary of published limits, not legal advice.
