Projectile-Resistant Film’s Role in School Security

There has been considerable debate about the role that projectile-resistant film plays in protecting students and staff at schools in Austin, TX, and nationwide. One argument is that, because security film does not create a bulletproof window, it may give those present a false sense of safety should a school shooting occur. 

The other side of the coin is that this solution is still useful in various circumstances. While not bulletproof, this projectile-resistant film does hold fragments of glass together, making it harder for an intruder to gain entry by breaking a window or glass door. It also protects those present by reducing shards of flying glass. 

Here, we’ll explore the two sides of the story and how schools are using this film.

What Is Projectile-Resistant Film?

This film is a thin polymer or polyester laminate applied to the surface of glass. The film is usually between 3 and 8 mils thick, with one mil equal to one thousandth of an inch. Projectile-resistant film, also known as security film, is designed to prevent glass from shattering upon impact by holding the broken pieces together. 

All schools in Texas are required to install security window film on ground-level windows and glass doors large enough to allow entry. 

The Benefits of Security Film

The reason schools require this application is that windows and doors are often a point of entry for those intending to harm students or staff. Installing an element designed to resist entry gives people time to reach a safe location and provides precious minutes for law enforcement to arrive. 

It’s estimated that a typical window with unprotected glass takes less than 10 seconds to break through and enter. Windows with projectile-resistant film can take 90 seconds to several minutes.

This film is also beneficial during Austin’s severe thunderstorms, which often bring large hail, straight-line winds with gusts up to 100 mph, and extreme rainfall. As with forced entry, the film keeps the broken glass together, limiting injury from flying shards.  

The Drawback of Projectile-Resistant Film 

One of the main arguments against using this film is that it’s not bulletproof and can lull potential victims into believing they are safer than they are. To circumvent this, training is essential for students and staff. 

At ASAP Security Services, we believe that projectile-resistant film and training are essential components of a comprehensive school security system. And Texas agrees.

The Uvalde Strong Act took effect in September 2025 to address critical failures in school safety protocols and law enforcement responses during active shooter events. In addition to several other mandates, it requires law enforcement, school personnel, and emergency medical services to undergo mandatory training and drills. 

In addition to security film, our security experts recommend integrating AI-smart video surveillance, access controls, and gunshot detection systems for comprehensive and scalable school protection.
