School security window film in San Antonio, installed by one of only two 3M Prestige Dealers in the city. 3M Safety and Security Window Film goes on your glass doors and ground-floor windows, holds the glass together when it breaks and slows down anyone trying to force their way in. Texas requires entry-resistant film on that glass in every school district and open-enrollment charter school.

3M Safety and Security Window Film for San Antonio schools
3M Safety and Security Window Film protects the weakest points of a school building, which are its glass doors and windows. It adds a layer of protection right where someone would try to get in. The Texas Education Agency (TEA) requires entry-resistant film on ground-floor windows, glass doors and windows near glass doors, so for most schools it isn’t optional any more.
The film keeps glass from flying into the room after an impact. 3M says it can delay an intruder by up to two minutes, and that’s time for law enforcement to get there. Government and commercial buildings all over the world use it.
It’s one of the security window film services we install across San Antonio. You’ll find everything else we do for buildings on our window tinting services page.
Texas requires security film on school glass
The Texas Education Agency set new school safety standards in November 2022. They require entry-resistant film on ground-floor windows, glass doors and windows near glass doors in every school district and open-enrollment charter school in Texas.
The rule covers windowed doors. It also covers windows next to or near a door that are big enough for someone to climb through if the glass broke. Glass inside a secured area is the exception.
When the standards came in, school systems had until August 2023 to hire a contractor. The state put up $400 million in grant funding to help districts meet the new standards. If some of your glass still isn’t covered, we’ll walk the campus with you and point out every pane the rule applies to.
See how 3M security film holds glass together
Security film doesn’t look like much once it’s on. The clear versions are close to invisible, so a parent walking into the front office won’t know it’s there.
The difference shows up when the glass gets hit. Instead of falling out of the frame, the broken glass stays stuck to the film. Anyone trying to get through has to keep working at a pane that won’t let go, and every second of that is time for help to arrive.
San Antonio's trusted 3M safety and security film installers
3M Safety and Security Film has been tested against bomb blasts and explosions. It’s also been tested against seismic events and spontaneous glass breakage. It can bring the glass you already have up to required safety glazing codes, without replacing a single window.
We’re a 3M Prestige Dealer, one of only two in San Antonio, and our installers are 3M certified. The film carries a strong warranty from 3M, and we’ve been putting film on San Antonio buildings since 1989.
MVISD Creek High School got more than 2,000 square feet of 3M security film from us over a two-month job. For me, school jobs come down to one thing: protecting the kids and staff.
What 3M Safety and Security Window Film does for a school
Once it’s on the glass, 3M Safety and Security Window Film does five jobs for a school.
- Reduces harm from shattered glass, whether the cause is a storm, an accident or a person
- Adds protection against smash-and-grab burglaries and break-ins
- Helps protect people and property from flying glass in storms and other natural disasters
- Can include sun control, like other 3M window films, to cut heat and glare and help furniture and flooring last longer
- Holds even stronger when it’s combined with the 3M Impact Protection Attachment System
That last one matters most on doors. The attachment system anchors the film to the frame, so the whole pane stays put instead of getting pushed in as one piece.
Where the film goes on a school, and when we install it
We start with the glass the rule covers: the entry doors, the windows beside them and any ground-floor window a person could reach from outside. The front office usually comes next. Then we work through the rest of the building if it makes sense to.
We plan the work around the school day. Most installs can happen after hours or over a weekend, when the only one in the hallway is the custodian with the floor polisher. St. Peter’s Catholic School in Boerne got 3M Ultra 800 on more than 100 windows in 4 days.
I’d rather quote a school for the glass that needs film than for every window in the building. Film on a second-floor window nobody can reach is money the school could spend on something else.
What security film can't do
Security film isn’t bulletproof, and no window film is. A bullet goes through filmed glass. What the film does is hold the broken glass in the frame, so getting through takes longer, and that time is the whole point.
The film is only as strong as its grip on the frame. On doors and big panes we recommend the 3M Impact Protection Attachment System, which anchors the film to the frame. We’ll tell you at the site survey which glass needs it and which doesn’t.
Film is one layer of a school’s safety plan. It works alongside locked doors, cameras, alarms and the staff who run the building. It doesn’t replace any of them.
School security film jobs we've done lately
Three recent projects
Bexar County Elections Office. More than 10,000 square feet of 3M security film, installed in 10 days, so the glass holds together instead of turning into a hazard.
School lobby. Tall glass in a school lobby we filmed. Big glass near the doors is where every school site survey starts.
Tall lobby glass. Our installers are aerial lift certified, so glass that’s out of reach from a ladder still gets done right.
St. Peter’s Catholic School in Boerne got 3M Ultra 800 security film on more than 100 windows, done in 4 days. MVISD Creek High School got more than 2,000 square feet of 3M security film over a two-month job. The Bexar County Elections Office got more than 10,000 square feet in 10 days.
We’ve installed more than 5 million square feet of film since 1989, on schools, offices, homes and cars.

School Security Window Film Frequently Asked Questions
Questions schools ask before the site survey
Does Texas require security film on school windows?
Yes. The Texas Education Agency’s school safety standards, set in November 2022, require entry-resistant film on ground-floor windows, glass doors and windows near glass doors. The rule covers every school district and open-enrollment charter school. Glass inside a secured area is the exception.
Is security window film bulletproof?
No. Security film holds glass together when it breaks and slows down forced entry. It doesn’t stop bullets, and no window film maker can honestly say it does.
How long can security film hold off an intruder?
3M says its safety and security film can delay an intruder by up to two minutes. How long it holds on your building depends on the film thickness, the glass and whether the film is anchored to the frame with an attachment system.
Can you install security film while school's in session?
Yes. We plan the work around classes, and most installs can happen after hours or over a weekend. We’ll agree the schedule with you before we start.
How long does a school security film job take?
It depends on the campus. St. Peter’s Catholic School took 4 days for more than 100 windows. MVISD Creek High School was a two-month job for more than 2,000 square feet. You’ll get a timeline with the quote.
How much does school security window film cost?
Every school gets a free site survey and a written quote. The film thickness, the amount of glass, whether you need an attachment system and how hard the windows are to reach all set the price.
Can security film go on our existing windows?
Yes. It goes on the glass you already have, from the inside. It can also bring older glass up to required safety glazing codes without replacing the windows.
What warranty comes with school security film?
It depends on the film. Most 3M commercial films carry a 12 to 15 year warranty, and we’ll show you the exact terms for your film before you sign anything.
Do you work on schools outside San Antonio?
Yes. We travel anywhere in Texas for security film jobs. St. Peter’s Catholic School is in Boerne.
