The Possibility of Applying Tint to the Outside of Window Glass

Introduction

Tinting window glass is a common practice to improve privacy, reduce glare, and enhance the aesthetic appeal of any building. While interior window tinting is widely recognized and accepted, many wonder if applying tint to the outside of the glass is feasible. This article explores the possibilities, considerations, and alternatives to achieve similar effects.

Understanding Exterior Tinting

Materials

The film used for exterior tinting is significantly different from interior films. Exterior films are specifically designed to withstand harsh weather elements such as UV rays, rain, and temperature changes. These films need to be durable, resistant to peeling, fading, and scratching to maintain their effectiveness over time.

Installation Challenges

Installation

Installing tint on the outside of the glass can be more challenging than interior installation. It may require professional installation to ensure proper adhesion and to avoid bubbles or creases. The process involves more steps and precise techniques, making it a complex task that professionals are better equipped to handle.

Extreme Effectiveness and Visibility

Effectiveness

Exterior window tint can be more effective in blocking heat and glare compared to interior tint. This is because it prevents sunlight from entering the building in the first place. However, if the tint is dark enough that others cannot see in, you may be able to see out during the day due to the increased brightness outside.

Alternative Solutions

Anti-graffiti Film

Anti-grafitti film is another option that can be applied to the exterior of storefront windows or other glass subject to vandalism. It provides a sacrificial layer of protection against scratching or acid etching. In most cases, this film can be removed and replaced at a lower cost than replacing the glass. Anti-graffiti film is much thicker than standard interior-applied tint films.

Laminated Glass

For those looking to install exterior tint without the risks associated with direct application, laminated glass is an alternative. Laminated glass involves storing the film between two pieces of glass, providing additional protection and longevity for the film. This method ensures the film will last longer without being exposed to the elements.

Building Codes and Regulations

Building Codes

Depending on local regulations, there may be restrictions on the type of film that can be applied to the exterior of windows, particularly in residential areas or historic districts. It is crucial to check local building codes and obtain any necessary permits before applying exterior tint.

Conclusion

While it is possible to apply tint to the outside of window glass, it is not advised unless there is a specific reason. The vast majority of tinting is done on the interior of windows to protect the film from the elements. However, for specialized needs, such as anti-graffiti protection or extreme heat resistance, exterior tinting can be a viable option. Consulting with a professional window tinting service is always recommended to ensure the best results.
