Window tint is applied to the outside of your car's glass. While some specialized films can be applied to the inside, this is far less common for automotive applications. Let's delve deeper into why outside application is the standard and explore some frequently asked questions.
Why is window tint applied to the outside?
The overwhelming majority of automotive window tints are installed on the exterior surface of the glass. This is due to several key factors:
-
Durability: Exterior application protects the delicate tint film from scratches, abrasion, and general wear and tear from inside the vehicle. Items like seatbelts, clothing, and even cleaning supplies can easily damage an interior film.
-
UV Protection: The primary purpose of many window tints is to block harmful ultraviolet (UV) rays. Applying the film to the outside provides a more effective barrier, preventing UV damage to the interior of your vehicle, as well as the glass itself.
-
Heat Reduction: Similarly, exterior application provides superior heat rejection. The tint acts as a physical barrier, reducing the amount of solar radiation that reaches the glass and the interior of your car. This is crucial for comfort and can significantly reduce the strain on your air conditioning system.
-
Installation Ease (Generally): While skilled professionals can achieve excellent results either way, installing tint on the outside is often considered a simpler and less error-prone process.
-
Better Adhesion: In many cases, exterior application leads to better adhesion of the tint film to the glass surface.
Can window tint be applied to the inside?
Yes, it's possible to apply window tint to the inside of a window, but it's less common for vehicles. Interior window films are often used for specific purposes such as:
-
Privacy: For applications where primarily privacy is needed and UV protection or heat rejection is secondary, interior tint might be considered.
-
Decorative Films: These films are often used to add a decorative element to a window, potentially in a home or office setting.
However, interior automotive window tinting is generally avoided due to the previously mentioned drawbacks concerning durability and longevity.
What are the advantages of exterior window tint?
We've already touched upon some of the key benefits, but let's summarize the advantages of exterior automotive window tinting:
- Superior durability: Protected from interior wear and tear.
- Enhanced UV protection: More effective at blocking harmful UV rays.
- Improved heat rejection: Keeps your car cooler and reduces AC strain.
- Increased privacy (often): Depending on the tint's darkness, it can offer increased privacy.
- Longer lifespan: Less susceptible to damage, resulting in a longer-lasting tint.
Does the placement of the tint affect its legality?
The legality of window tint is primarily determined by the tint's darkness (VLT – Visible Light Transmission) and sometimes the location (front side windows vs. rear windows). Whether the tint is applied inside or outside doesn't typically affect its legality, though local laws vary considerably. Always check your local laws and regulations before applying window tint to your vehicle.
How long does window tint last?
The lifespan of window tint depends on several factors, including the quality of the film, the installation process, and environmental conditions. However, with proper care and installation, high-quality exterior window tint can last for many years, often 5-10 years or even longer.
By understanding the differences and benefits, you can make an informed decision about the best option for your vehicle's needs. Remember to always consult with a professional window tinting service for proper installation and to ensure compliance with local laws.
