Southwest ISD: School Safety Window Film

Security film for school glass

Epic Security & Architectural Window Films and Graphics installs 3M security window film on K-12 campuses. Security film keeps broken glass in the frame, making it more difficult for potential intruders to break in. No window film is bulletproof, so security film is one layer of entry hardening, alongside locked vestibules, cameras and trained staff. Installations done right…every time.

3M security films Epic installs for schools

Each film below is anchored to the frame with the 3M Impact Protection Attachment (IPA). 3M requires the IPA for break-and-entry, windstorm and explosion-mitigation applications. IPA installed the Epic way.

• 3M S2400: The only polyurethane security film we know of — every other security film on the market is polyester (PET). About 4X the elongation (560% vs 130%) and two-thirds more Graves tear resistance (24.6 vs 14.8 lbf·in) than a 22-mil PET security film, by 3M’s published data — and installed anchored to the frame with the Epic Method, never film-only.
• 3M Ultra S800: The 3M security film tested for blast, impact and seismic events — installed anchored to the frame, never film-only.
• 3M Ultra Prestige: The Prestige solar stack bonded to a micro-layered safety film — one installation for heat, UV and glass retention.
• 3M Ultra Night Vision: Night Vision solar performance on a micro-layered safety film — for buildings that need both and do not want a mirror.
• 3M S140: 14-mil security film for smash-and-grab, vandalism and accidental breakage — sized to the risk and priced to the budget.
• 3M Safety Series: Clear 4-, 7- and 8-mil safety films for human-impact codes, spontaneous breakage and everyday glass hazards — interior and exterior grades.
