Yes, you can put tint on the outside of house windows, but it’s generally less common than interior tinting. Exterior window tinting can be suitable in certain situations, and there are specific films designed to withstand outdoor conditions.

Here are some considerations and scenarios where exterior window tinting might be applied…

Advantages of Exterior Window Tinting

• Specialized Needs – Some window types or building regulations may necessitate the use of exterior window tint. For example, windows that cannot be accessed from the inside or special types of glass that might be sensitive to internal tinting.
• Heat Rejection – Exterior window films can block UV rays and heat before they enter the glass, potentially offering a slight advantage in heat rejection compared to interior films.
• Protective Coatings – Modern exterior window tints are designed with protective coatings to resist weather, UV degradation, and scratches, making them more durable for outside use than traditional films.

Considerations

• Durability – Even though exterior films are made to be more durable, they are still more exposed to the elements than interior films. This can lead to a shorter lifespan and more frequent replacements.
• Installation and Maintenance – Installing film on the exterior can be more challenging, especially for high or hard-to-reach windows. Maintenance and cleaning may also pose more difficulty compared to interior films.
• Aesthetics – Depending on the film, exterior tinting might have a different visual impact on your home’s appearance. It’s crucial to consider how the tint will look from both the outside and inside.
• Local Regulations – Some localities or homeowners’ associations (HOAs) may have specific rules regarding the appearance of exterior window treatments. It’s advisable to check these regulations before proceeding with exterior tinting.

Application and Use

• Professional Installation – For exterior window tinting, professional installation is highly recommended to ensure that the film is applied correctly and to maximize its lifespan and effectiveness.
• Weather Considerations – The best time for application is during mild weather conditions to ensure proper adhesion and curing of the film.

Conclusion

While it’s possible and sometimes necessary to apply tint to the outside of house windows, it requires careful consideration of the film’s durability, the specific needs of the windows, and the aesthetic impact. Exterior window films specially designed for outdoor use can offer a viable solution for certain situations but always consult with a window tinting professional to choose the best option for your home.
