The question of whether ceramic tint should be applied inside or outside the window is common, and the answer is straightforward: Ceramic tint is applied on the inside of the window.
3.2.1 Inside Installation
Installing ceramic tint on the inside of the window is the industry standard for several reasons:
- Protection from the Elements: When applied inside, the tint is protected from external elements such as rain, snow, wind, and debris. This reduces the risk of damage and extends the tint’s lifespan.
- Easier Maintenance: Interior application makes it easier to clean and maintain the tint, as it is less likely to accumulate dirt, grime, or scratches.
- Better Adhesion: Window films are designed to adhere more effectively to the smooth, clean surface of the interior glass. This results in a more durable bond and reduces the risk of peeling or bubbling.
- UV Protection: Since UV rays penetrate through the glass, applying the tint on the inside still provides excellent protection against UV radiation, preventing interior fading and skin damage.
3.2.2 Outside Installation
While some specialized films are designed for exterior application, these are typically used for specific purposes, such as temporary protection or exterior architectural tinting. Applying ceramic tint on the outside of a vehicle or residential window is generally not recommended for the following reasons:
- Exposure to the Elements: Exterior application leaves the tint exposed to weather conditions, which can lead to faster degradation, peeling, or bubbling.
- Increased Wear and Tear: Exterior tint is more susceptible to scratches, chips, and other damage caused by road debris, car washes, or environmental factors.
- Shorter Lifespan: Due to the increased exposure to harsh conditions, exterior tints typically have a shorter lifespan and may require more frequent replacement.
3.3 The Installation Process
The installation of ceramic window tint requires precision and attention to detail. Here’s an overview of the steps involved in the proper installation of ceramic tint on the inside of the window:
3.3.1 Cleaning the Window
Before applying the tint, the window must be thoroughly cleaned to remove any dirt, dust, or contaminants. Any residue on the glass can interfere with the adhesive and lead to bubbles or imperfections.
3.3.2 Measuring and Cutting the Tint
The tint film is measured and cut to fit the specific dimensions of the window. It’s essential to cut the film slightly larger than the window to allow for adjustments during installation.
3.3.3 Applying the Tint
The tint film is carefully applied to the inside of the window using a solution that allows the film to slide into place. The installer then uses a squeegee to remove any air bubbles and excess solution, ensuring a smooth, even application.
3.3.4 Trimming Excess Film
Once the tint is properly positioned, any excess film is trimmed away, and the edges are sealed to prevent peeling.
3.3.5 Curing Time
After installation, the tint needs time to cure and fully adhere to the glass. During this period, it’s important to avoid rolling down the windows or cleaning the glass to prevent disrupting the bond.
4. Common Misconceptions About Ceramic Tint Installation
4.1 Misconception: Ceramic Tint Can Be Applied on the Outside for Better Heat Rejection
Some people mistakenly believe that applying ceramic tint on the outside of the window will improve heat rejection. However, ceramic tint is designed to work effectively when applied on the inside, as the glass itself helps to absorb and reflect heat. External application does not significantly enhance heat rejection and can lead to premature wear of the tint.
4.2 Misconception: Exterior Tinting is Necessary for UV Protection
Another misconception is that exterior tinting is required to protect against UV rays. In reality, ceramic tint provides excellent UV protection when applied on the inside, as it blocks UV rays before they penetrate the interior.
