The question of whether window tint goes on the inside or outside is a common one, and the answer isn't always straightforward. While most residential and automotive window tinting is applied to the inside of the glass, there are exceptions and important considerations for both interior and exterior applications. Let's delve into the details.
Why is Window Tint Typically Applied to the Inside?
The overwhelming majority of window tinting is installed on the interior surface of the glass for several key reasons:
-
Protection from the Elements: Exterior tint is exposed to harsh weather conditions like sun, rain, snow, and extreme temperatures. This can lead to premature fading, cracking, peeling, and overall shorter lifespan compared to interior tint. Interior tint is shielded from these elements, significantly extending its longevity.
-
Easier Installation and Maintenance: Applying tint to the interior surface provides a more controlled and stable environment for installation. It's easier for installers to work with the film and ensure a precise, bubble-free application. Cleaning and maintenance are also simpler as you don't need ladders or specialized equipment to reach the exterior.
-
Enhanced Safety and Security: In the event of breakage, interior tint helps hold the shattered glass together, minimizing the risk of injury from flying fragments. While exterior tint can offer some security benefits, interior tint is generally considered more effective in this regard.
-
Improved Aesthetics: Interior tint tends to provide a cleaner, more polished look. Exterior tint, being directly exposed, can accumulate dirt and grime more quickly, potentially impacting its appearance.
Can Window Tint Be Applied to the Outside?
Yes, while less common, exterior window tinting is sometimes used. This is often seen in specific commercial or industrial applications where specialized properties are needed, such as:
-
High Heat Rejection: Certain exterior films are designed to reflect a higher percentage of infrared radiation, effectively reducing the amount of heat entering the building. This can be beneficial in extremely hot climates.
-
Security Applications: In security-sensitive environments, exterior tint might be used in conjunction with interior tint to create an additional layer of protection against vandalism or intrusion.
-
Specific Architectural Designs: In some architectural designs, exterior tint might be integrated for aesthetic or design purposes.
What About Safety and Security Films? Are They Inside or Outside?
Safety and security films, designed to hold glass together in case of breakage, are typically installed on the inside of the window. This placement provides maximum effectiveness in preventing shattered glass from causing injury or damage.
Which is Better: Inside or Outside Tint?
For most residential and automotive applications, interior tint is the superior choice. It offers better protection, easier installation, enhanced safety, and improved aesthetics at a lower cost. Exterior tint may have specific applications, but its drawbacks in terms of longevity and maintenance often outweigh the benefits for typical uses.
What are the downsides of exterior window tint?
Exterior window tint, despite certain applications, carries some significant downsides:
-
Shorter Lifespan: Constant exposure to the elements greatly reduces the lifespan of exterior tint.
-
Higher Maintenance: Cleaning and maintenance are more challenging and costly.
-
More Difficult Installation: Professional installation is almost always necessary, adding to the cost.
-
Potential Damage: The tint is vulnerable to damage from debris and extreme weather conditions.
By understanding the pros and cons of each application method, you can make an informed decision about the best type of window tint for your needs. Always consult with a professional window tinting installer for advice tailored to your specific situation.
