tint?<\/h3>\n\n\n\n<p><strong>A1:<\/strong> Visible Light Transmission (VLT) is the percentage of light that passes through glass and tint.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Q2: Why don\u2019t tint percentages add up?<\/h3>\n\n\n\n<p><strong>A2:<\/strong> Because tint layers multiply, not add, resulting in a lower final percentage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Q3: What is a good tint percentage?<\/h3>\n\n\n\n<p><strong>A3:<\/strong> Around 35\u201350% offers a balance of visibility and privacy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Q4: Can tint percentage be illegal?<\/h3>\n\n\n\n<p><strong>A4:<\/strong> Yes, many regions have legal limits based on final VLT.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Q5: Does darker tint block more heat?<\/h3>\n\n\n\n<p><strong>A5:<\/strong> Not always\u2014heat rejection depends on film quality, not just darkness.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Film VLT (%) Glass VLT (%)
