Window tint is almost always applied to the outside of your car's windows. While there are extremely rare exceptions (like specific interior films with limited functionality), applying tint to the exterior is the standard practice and offers numerous advantages. This article will delve into the reasons why exterior application is preferred, address common misconceptions, and answer frequently asked questions surrounding window tinting placement.
Why is Window Tint Applied to the Outside?
The overwhelming preference for exterior window tinting stems from several key factors:
-
Durability and Longevity: Exterior tint is directly exposed to the elements, but the specialized films are engineered to withstand UV rays, extreme temperatures, and scratches. Interior tint, on the other hand, would be more vulnerable to damage from interior elements, such as cleaning products or accidental scratches. This difference significantly impacts the tint's lifespan.
-
Superior Heat Rejection: Exterior window tint creates a protective barrier that reflects solar heat and UV rays before they reach the glass. This leads to more effective heat reduction inside the vehicle compared to interior tint, which can only absorb some of the heat already transferred through the glass. This makes a noticeable difference in fuel efficiency, especially in hot climates.
-
Better Protection Against Fading: UV rays are a major culprit in interior fading. Exterior tint significantly reduces the amount of UV radiation entering the vehicle, protecting your upholstery, dashboard, and other interior components from sun damage.
What About Interior Window Tint?
While extremely uncommon for vehicles, interior window tint does exist. It’s typically used in applications where exterior tint isn't feasible or desirable, such as:
-
Privacy films on office windows: These primarily serve a privacy function and aren't designed for heat rejection or UV protection to the same extent as automotive exterior window tint. They are thinner and less durable.
-
Specialized decorative films: Some interior films add decorative patterns or designs to the inside of windows. They're largely aesthetic rather than functional.
Is it Possible to Apply Tint to Both Sides?
No, applying tint to both the inside and outside isn't recommended. It would be redundant, reduce visibility, and potentially create an uneven appearance. The added layers might also affect the tint's performance and longevity. The primary purpose of window tint is effectively met through professional, exterior application.
How Long Does Exterior Window Tint Last?
The lifespan of professionally installed exterior window tint varies depending on factors like film quality, climate, and proper care. High-quality films can last for several years, even a decade or more, with minimal degradation. However, it's a good idea to periodically inspect the tint for any signs of wear or damage.
Can I Install Window Tint Myself?
While DIY window tint kits exist, it's generally advisable to have your tint professionally installed. Professionals possess the expertise and tools to ensure a flawless, bubble-free application, guaranteeing optimal performance and longevity. An improperly installed tint can lead to bubbling, peeling, and other issues.
What are the Legal Limits for Window Tint?
Window tint laws vary widely depending on your location (state, province, country). It's crucial to check your local regulations before getting your windows tinted to avoid potential fines or legal issues. These laws often specify allowable tint darkness (VLT – Visible Light Transmission percentage) for the front side and rear windows.
By understanding the benefits of exterior window tint and addressing common misconceptions, you can make an informed decision that best suits your needs and complies with local regulations. Remember to always choose a reputable installer to ensure a high-quality, long-lasting result.
