HOW DARK CAN WINDOW TINT BE IN COLORADO?
Darkness of tint is measured by Visible Light Transmission percentage (VLT%). In Colorado, this percentage refers to percentage of visible light allowed in through the combination of film and the window.
Windshield – Non-reflective tint is allowed on the top 4 inches of the windshield.
Front Side Windows – Must allow more than 27% of light in.
Back Side Windows – Must allow more than 27% of light in.
Rear Window – Must allow more than 27% of light in.
HOW REFLECTIVE CAN THE TINT BE IN COLORADO?
Similar to sunglass lenses, some tinting film contain metallic elements that help in reflecting incoming light and reducing the glare and heat generated by visible light.
Front Side Windows – No metallic or mirrored appearance.
Back Side Windows – No metallic or mirrored appearance.
