Security window film · forced entry, blast & safety glazing

Keep the glass in the frame. Keep the threat outside.

Security window film is a thick polyester or polyurethane film bonded to your existing glass and — critically — anchored to the frame, so broken glass stays in place during forced entry, blast or storms. Epic installs 3M security film nationwide with the patent-pending Epic Method for schools, government, retail, healthcare, houses of worship and homes. Not bulletproof. Engineered to hold the fragments in the frame and deny the easy opening.

What it protects against

Six threats, one retrofit.

Forced entry & active threat

Keeps broken glass in the frame so the first strikes don’t create an opening. Time is the product: every second an intruder spends at the glass is a second for lockdown and response.

Smash-and-grab

Storefronts, pharmacies, dispensaries, dealerships. Film plus attachment turns a quick smash-and-grab into a loud, slow attempt — in the open, under lights, on camera.

Blast mitigation

Reduces flying-glass hazard — the leading cause of injury in an explosion — by holding fragments to the film. Rated to ASTM F1642 / GSA TS01.

Windstorm & debris

Attached film helps the glazing resist wind-borne debris and pressure cycling; a 3/8" structural silicone sealant bead meets windstorm attachment requirements.

Seismic & spontaneous breakage

Tempered glass can fail on its own (nickel-sulfide inclusions). Film holds the shards. Recommended on single-pane tempered glass where spontaneous breakage is a concern.

Safety glazing compliance

Retrofit existing annealed glass to meet ANSI Z97.1 / CPSC 16 CFR 1201 in doors, sidelites and hazardous locations without replacing glass.

Real world · Godley ISD, Texas · September 2023

The storm broke every window. The filmed ones stayed closed.

A windstorm lifted rock ballast off a Godley ISD roof and threw it through the glass below. The entry and lower windows Epic had filmed shattered — and stayed in their frames. The unfilmed windows blew out.

With the glass already broken, the district did what most people only talk about: it had its own police officers attempt a forced entry through the filmed openings, and Epic demonstrated the attachment alongside them. They went at the broken, filmed glass with tools and weapons. The district’s own words, in the letter it wrote afterward: “we observed a significant delay in forced entry.” Their conclusion, in their words: that level of protection “reinforces our confidence” — and the storm had already shown that the glass stays in the frame. Godley ISD’s signed reference letter is on the References page.

Security film does not make glass unbreakable or bullet-resistant. Attached to the frame, it keeps broken glass in the opening, making it more difficult for an intruder to break in.

Privacy and signage over security film · an Epic process

Frost it, number it, brand it — without touching the security film.

Every building that installs security film asks the same question a week later: now how do we put the room numbers back? Or the privacy band, the visitor decal, the mascot? The industry answer is "you can't" — anything stuck to security film pulls at it when it comes off, and a lifted edge is a warranty problem. Epic worked out a better answer.

We print and apply a second, film-safe layer on top of the installed security film: a custom-printed frost or privacy band, a printed graphic, door and classroom numbers, security and visitor decals, logos, hours — on a removable-adhesive PET film Epic developed for exactly this. It bonds to the security film without affecting it, holds up to daily use, and when the room changes or the sign is retired it peels off clean — no residue, no lifted edge, the security film underneath exactly as we left it, and Epic stands behind the layer and its removal. It is cut on Epic Precision, printed at VisuFlare and installed by the same crews that installed the security film.

  • Frost or privacy band over security film on offices, conference rooms and classroom doors
  • Door and classroom numbering and wayfinding, cut to the district's standard
  • Security, visitor and compliance decals that can be updated without re-filming the glass
  • Printed graphics and branding — mascots, color bands, logos — on secured glass
  • Removable: changes and renewals are a quick visit, not a film replacement

How it started. A county government building in Albuquerque, New Mexico needed 3M security film on its street-level glass for forced-entry and blast mitigation — and the workstations behind that glass carried sensitive information on their screens, in full view of the sidewalk. Film alone solves one problem and leaves the other. Epic installed 3M Scotchshield S2400 with the Epic Method, then a custom-printed frost band over it at screen height: privacy from the street, daylight above and below, and a layer that lifts off clean if the floor plan ever changes. The same process has since numbered every classroom window and entry across a Colorado school district, over the security film — double-sided numbers that read from the corridor and from the parking lot, the district’s security decals in the entry glass, and reusable holders on the same media so a school can post a flyer on the glass for a day, a week or a month, take it down and use the holder again.

After the install

Every window has a record — and initials on every step.

Each installer logs every window in Epic’s app and initials each step — cleaning, gasket out, wedges, film, solvent wipe, tape, the structural bead, cleanup. Every building we have worked on is cataloged by room and opening with its measurements and film code, so a repair starts with a photo and a room number, not a re-survey. With your permission, a one-inch Epic tag in the corner tells whoever runs the building next who to call. How the record works →

The films

Choose by threat, not by price list.

Start with 3M S2400: the most advanced security film the industry has seen, and the only polyurethane one we know of — every other manufacturer’s security film is polyester (PET), which tears where polyurethane stretches. Every film below has an Epic spec card you can download. Each one is installed by Epic’s own certified teams — and for forced-entry, blast and windstorm, always with the Epic Method.

FAQ

Security window film questions

Which security film should I choose?
It depends on the threat and the glass. For forced-entry resistance on entries and vestibules, 3M S2400 (24-mil polyurethane) attached with the Epic Method is the highest-rated option in the 3M line. Ultra S800 is the micro-layered multi-threat film for blast, break-in and seismic. Ultra Prestige or Ultra Night Vision add sun control. S140 covers everyday smash-and-grab and safety-glazing needs. A free assessment tells you which — and shows you why.
Is security film bulletproof or bullet-resistant?
No. No window film is bulletproof, bullet-resistant or ballistic, whatever name it is sold under. Security film keeps broken glass in place, making it more difficult for an intruder to break in, and reduces flying-glass injury; it does not stop projectiles. Anyone who tells you otherwise is the reason we publish a buyer’s guide — and a page that decodes “ballistic,” “NIJ-rated” and “UL 752” claims.
What makes a 3M security film different from a standard safety film?
Engineering. A standard safety film is a single sheet of polyester (PET) — strong until it is nicked, then it tears like paper. 3M’s Ultra series is micro-layered: many micro-layers bonded together, so a tear that starts in one layer cannot run through the next. The easiest way to picture it is ripstop fabric — the hunting jacket, pack or tent fly with the woven grid that stops a rip from spreading. Ultra S800 is ripstop in film form. 3M S2400 goes a step further with a different material altogether: polyurethane, which stretches and absorbs energy where polyester tears, and is the only polyurethane security film we know of. See polyurethane vs. PET security film for the published numbers.
Film alone or film with attachment?
Film alone addresses safety glazing and spontaneous breakage. For forced entry, blast and windstorm, 3M specifies its Impact Protection Attachment (IPA) — a structural silicone sealant anchoring the film to the frame — and so does Epic, because without it the filmed glass can leave the frame in one piece. Epic installs 3M IPA on every forced-entry job. How it is installed is the whole difference; see the Epic Method.
What about ASTM F3561 — does Epic’s film meet it?
ASTM F3561 is a forced-entry test written for complete, factory-built window and door systems; 3M and the International Window Film Association both state that retrofit film is not covered by it, and Epic agrees. Because the requirement is appearing in school and government RFPs anyway, Epic had its installed system tested to it independently — so the data exists and Epic has a seat at that table — but the test is not the right yardstick for retrofit film, and Epic does not sell on it. Why that is, and what the standard was written for, is explained in The Retrofit Gap on the Epic Method page.
How long does installation take?
A typical school or commercial entry package — doors, sidelites and ground-floor windows — installs in days, not weeks, with no glass replacement and minimal disruption. We schedule around occupancy: nights, breaks, and summer for schools.
What warranty comes with it?
Security films carry 3M’s commercial warranty (10 years on S2400; up to 15 on Ultra Prestige) when installed by a 3M-authorized dealer. Epic’s installation guarantee sits on top of it.

Founder credentials

Before Epic, Chris Eder’s prior company worked on federal buildings, embassies and the Smithsonian.

Before Epic, Chris Eder’s company was the one the federal government and the State Department called when the glass had to hold — and when it had to stay invisible: every EPA facility across the nation including the entire Federal Triangle, agency headquarters throughout Washington, the Smithsonian, and complete U.S. embassies and ambassadors’ residences on three continents — Rome, Malta, Luxembourg, the Vatican, Kazakhstan. The buildings named below are a sample, not the list. It is why a school district or a building owner can trust the same hands and the same standard today.
