In the following sections, we’ll explore the pros and cons of each installation method in more detail, helping you determine the best approach for your specific situation.
Does Window Film Go On The Inside Or Outside?
When it comes to applying window film, one of the most common questions people ask is whether it should be installed on the inside or outside of the window. The answer depends on several factors, including the type of film, the purpose of the film, and the condition of the window. In this article, we’ll explore the pros and cons of installing window film on the inside versus the outside of the window.
Inside Window Film Installation
Installing window film on the inside of the window is the most common method. This is because it provides a cleaner and more controlled environment for the film, which helps to ensure a smooth and bubble-free installation. Here are some benefits of installing window film on the inside:
- Easier installation: The inside of the window is generally cleaner and smoother, making it easier to apply the film.
- Less exposure to elements: The film is protected from the outside elements, such as weather, dirt, and debris, which can damage the film over time.
- Better visibility: The film is applied to the inside of the window, which means it won’t obstruct the view or create a reflective surface that can cause glare.
However, there are some situations where installing window film on the inside may not be the best option. For example:
- Double-pane windows: If you have double-pane windows, installing the film on the inside may not be effective, as the film may not be able to reach the outer pane of glass.
- Low-e windows: If you have low-e windows, installing the film on the inside may not be compatible with the window’s coating, which can cause the film to fail prematurely.
Outside Window Film Installation
Installing window film on the outside of the window is typically used for specific types of films, such as exterior window films that are designed to provide additional protection against weathering, fading, and graffiti. Here are some benefits of installing window film on the outside:
- Additional protection: Exterior window films can provide an extra layer of protection against weathering, fading, and graffiti.
- Improved durability: Exterior window films are designed to withstand the elements and can last longer than interior films.
- Enhanced security: Exterior window films can make it more difficult for intruders to break the glass, providing an added layer of security.
However, there are some drawbacks to installing window film on the outside:
- More difficult installation: The outside of the window may be dirty, rough, or uneven, making it more challenging to apply the film.
- Exposure to elements: The film is exposed to the outside elements, which can cause it to degrade faster.
- Increased risk of damage: The film may be more prone to damage from weather, debris, or vandalism.
When to Choose Inside or Outside Installation
So, when should you choose to install window film on the inside versus the outside? Here are some general guidelines:
| Type of Film | Installation Location |
|---|---|
| Decorative films | Inside |
| Solar control films | Inside |
| Exterior window films | Outside |
| Safety and security films | Outside |
In general, if you’re looking to improve the energy efficiency, reduce glare, or enhance the appearance of your windows, installing window film on the inside is usually the best option. However, if you need to provide additional protection against weathering, fading, or graffiti, or enhance the security of your windows, installing window film on the outside may be the better choice.
Ultimately, the decision to install window film on the inside or outside of the window depends on your specific needs and the type of film you’re using. Be sure to consult with a professional installer to determine the best installation method for your particular situation.
