Arizona specifies 33% light transmission, plus or minus 3%, and 35% reflectance, plus or minus 3%, for film combined with the glass. A film labeled “35%” alone does not establish compliance.
602.677.7937Get a quoteThe percentage is how much visible light passes through. A 70% film is lighter than a 20% film. The number is not the percentage of heat blocked.

35% VLTA visibly tinted appearance. The final glass-and-film reading still matters.
Discuss this shadeIllustrative preview, not a measured glass simulation. Real appearance varies with lighting, glass and film. VLT is visible light transmission, not heat rejection. These shades are not approvals for every window.

Existing glass already reduces some light. Adding film reduces transmission again.
Glass transmission × film transmission
= approximate combined transmission.
A light meter checks the actual installed result.

Different provisions apply behind the driver, including reflectivity and mirror requirements. Confirm the treatment for your vehicle.
The statute allows a qualifying topmost strip with positioning and color restrictions. Do not assume a light full-windshield film is permitted.
Verify the current rules and actual glass measurement before installation. Tint installed on driver or passenger side windows may be illegal in other states.
No. VLT measures visible light, not total solar energy. Film construction and solar-performance specifications matter, too.
No. A 5% film still transmits very little visible light. Ceramic technology does not remove the visibility tradeoff of a dark shade.
Vista can discuss the appearance you want. Matching darkness alone does not establish matching heat control, and existing glass affects the installed result.
