Commercial Security Window Film

Security Window Film | Portland, OR

What Is a Security Window Film?

Imagine if you could reinforce tempered glass, which is designed to shatter easily under impact. With a security window film in Portland, you can do exactly that.

Besides adding an extra layer of strength to your organization’s windows, these films (also called storefront security films, glass reinforcement films, anti-graffiti films, and safety films) are optically clear. That means you don’t have to worry about obstructing those breathtaking views or keeping natural light from getting into your premises.

They’re even designed not to alter the appearance of the glass – so much so that signage can be applied on top without any issues. Interested? Contact us today for a free quote!

Benefits of Using Security Window Film | Portland, OR

When it comes to your commercial property, security window film offers multiple advantages beyond just preventing robberies and destruction.


These films are designed to hold glass together when under stress. That means if an unwanted guest tries smashing through, they’re met with resistance instead of shattered shards.


Our commercial security films are optically clear, so you don’t have to worry about obstructing views or changing appearances. You also get an extra level of protection against vandalism.

Types of Security Window Films

The selection of the best safety and security window film in Portland for a building depends primarily on the type and location of the glass. In addition, the required level of security against forced entry will help determine what is needed.

These films are categorized by the level of protection they provide and when applied and are bonded securely to the window, making entry extremely difficult. Most applications will not require more than 4-8 mil thick, though there are security films on the market up to 14 mil thick. We offer both clear and tinted options if you would like to control solar heat gain as well.

Whether you’re looking for interior or exterior window film, we can help. Both options are clear and do not change the appearance of the glass.

Installation Process for Security Window Film

The first step in installing security window film is a thorough cleaning of the glass surface. This ensures that no dust or debris interferes with the adhesion process. Once clean, we will measure and cut the film to fit each individual pane of glass. Accuracy here is key, as even small gaps can compromise safety.

Most commercial storefronts use tempered glass, which shatters easily. Installing security window films on this type of glass not only strengthens it against break-ins but also helps hold together shattered pieces if an incident does occur.

Our trained installers ensure that every installation meets industry standards. We make sure that all edges are sealed tightly, especially when dealing with tempered glass, creating an almost invisible layer of protection over your windows without altering their appearance or blocking natural light.

Maintenance and Care for Security Window Films

Here are some tips for maintaining your window film:

Cleaning the Film

Start with water and a mild detergent. Use a soft cloth or sponge – never anything abrasive that might scratch the surface. Rinse thoroughly, and dry using another clean, soft cloth.

Avoiding Damage

Steer clear of harsh chemicals (like ammonia-based cleaners), which can degrade its quality over time.

Film Replacement

If you notice blisters, peeling off, or discoloration, don’t be alarmed. These are signs that your security window film needs replacement. But don’t try doing this yourself, as improper removal could cause more harm than good. Call our experienced staff when it comes to replacing security window films for commercial storefronts.
