Window tinting in Colorado
High-altitude sun in Colorado burns through glass even when the air is cool. Front and rear glass both have a lightness floor, so the film has to reject heat without going too dark.
In Colorado, front side windows must let at least 27% of visible light through. Rear glass must let at least 27% of visible light through on a normal install. 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.
