3M™ Safety Film Series · installed by Epic

When glass breaks, it stays put.

Clear 4-, 7- and 8-mil safety films for human-impact codes, spontaneous breakage and everyday glass hazards — interior and exterior grades.

Not every opening needs forced-entry film. Classroom doors, corridor glass, overhead lites and older annealed glass need to meet human-impact codes and hold together if they break. The Safety Film Series does exactly that: clear polyester films from 4 to 8 mil that keep broken glass in one sheet instead of on the floor. Where the risk is break-in, Epic moves you up to S140, Ultra S800 or S2400 with the Epic Method attachment; where it is breakage, these films are the right-sized answer.

  • Overhead and sloped glazing

What it does, and where it belongs.

S40, S70 and S80 are optically clear polyester safety films that pass the ANSI Z97.1 Class B 150 ft-lb impact test on annealed glass, which is how existing glass is upgraded toward human-impact safety glazing requirements without replacement. S40 and S70 are also made in exterior grades with a weatherable adhesive for balcony glass, skylights and the outer pane of an insulated unit. 3M does not rate these films for windstorm or blast; that is what the attached security films are for.

Why buildings choose 3M Safety Series

  • Holds broken glass: Shards stay bonded to the film instead of falling or flying.
  • Code compliance: Upgrades existing annealed glass toward human-impact safety glazing requirements (ANSI Z97.1 Class B).
  • Invisible: 86–87% visible light, no tint, no change to the look of the glass.
  • Interior or exterior: S40 and S70 available in exterior grades for glass that cannot be reached from inside.
  • UV protection: Blocks 99% of UV.

How Epic installs this film

Safety films are bonded to the glass by Epic-employed Certified Installation Specialists, precision-cut and kitted by opening. Because 3M does not approve the Safety Series for windstorm or blast applications, Epic installs it without the structural attachment — and specifies S140, Ultra S800 or S2400 with 3M IPA installed the Epic way wherever an opening needs forced-entry, blast or windstorm performance. The survey tells you which openings are which.

Important. Safety films are not forced-entry films, and 3M does not rate them for windstorm or blast. For those applications see 3M S140, Ultra S800 and S2400 installed with 3M IPA the Epic way. No window film is bulletproof or bullet-resistant.

What sets 3M Safety Series apart

  • Right-sized protection — 4, 7 and 8 mil: match the film to the hazard, not the catalog.
  • Tear resistance — Polyester construction engineered to hold under impact.
  • Durable hard coat — Scratch-resistant for routine cleaning.
  • Epic installation — Precision-cut, kitted and installed by Epic’s in-house, certified crews.
  • Upgrade path — Same installer, same crew when an opening calls for security film and attachment.

Where Epic installs 3M Safety Series

On classroom doors, corridor and overhead glass, commercial and retail glass and homes where the hazard is breakage and human impact, not break-in. Where an opening needs forced-entry, blast or windstorm performance, Epic specifies S140, Ultra S800 or S2400 with 3M IPA installed the Epic way; buy either through cooperative contracts.
