20% Tint vs. 35% Tint: Understanding Window Film Darkness
Choosing the right window tint for your car or home involves understanding the VLT (Visible Light Transmission) percentage. The lower the VLT number, the darker the tint. So, the simple answer is: a 20% tint is darker than a 35% tint.
Let's break down what this means and help you make an informed decision:
Understanding VLT Percentages
VLT percentages represent the amount of visible light that can pass through the window film. A 100% VLT means the film is completely clear, allowing all light to pass through. Conversely, a 0% VLT means no light can pass through—it's completely opaque.
-
35% VLT: This allows a significant amount of light to pass through, resulting in a relatively light tint. It offers some privacy but still maintains good visibility. This is often a popular choice for those seeking a balance between privacy and light transmission.
-
20% VLT: This is a much darker tint, allowing only 20% of visible light to pass through. It provides more privacy and significantly reduces glare, but visibility can be somewhat reduced, especially at night.
Factors to Consider Beyond the Numbers
While the VLT percentage is the most important factor, other elements influence the perceived darkness:
-
Film Type: Different types of window films (dyed, metallic, ceramic) can affect the overall darkness and appearance, even with the same VLT percentage. Metallic films, for example, often appear darker than dyed films with the same VLT.
-
Color: The tint's color can influence how dark it appears. A dark grey tint might seem darker than a dark charcoal tint, even if both have the same VLT.
-
Lighting Conditions: How dark a tint appears will vary based on the surrounding light. A 35% tint might appear darker at night or in low light conditions compared to a sunny day.
Legal Considerations
It's crucial to check your local laws and regulations regarding window tint percentages. Many areas have legal limits on how dark your window tint can be, especially for the front side windows. Exceeding these limits can result in fines.
Making the Right Choice for You
The best tint percentage depends on your priorities:
-
Maximum Privacy: Opt for a lower VLT percentage like 20% or even lower (though legality must be considered).
-
Balance of Privacy and Visibility: A mid-range VLT like 35% might be ideal.
-
Heat Reduction: While VLT impacts light, it doesn't directly correlate with heat reduction. Look into films that specifically advertise high heat rejection properties for optimal temperature control.
Ultimately, considering both the numerical VLT and the other factors discussed above will help you choose the perfect window tint that meets your needs and complies with local regulations. Visiting a professional window tinting shop is highly recommended for personalized advice and a precise installation.
