Security Window Film for Texas Schools & Commercial Buildings

3M authorized dealer installing Ultra S800, S140 and S240 safety and security film — hardening campus entries, classroom glass and storefront glazing so a break-in becomes a loud, slow, visible failure instead of a two-second entry.

Quick Answer

Quick answer

Security window film is a thick, optically clear laminate bonded to the inside face of existing glass. It does not stop the glass from breaking — it keeps the broken glass in the frame, so an intruder has to strike and tear the same panel repeatedly to get through. LeWolf is a 3M authorized dealer installing 3M Ultra S800, S140 and S240 for Texas school districts and commercial buildings, to IWFA installation standards.

3M Authorized Dealer

3M Ultra S800, S140 & S240 Security Film

The 3M Ultra series is built from hundreds of tear-resistant micro-layers rather than one thick sheet of polyester. That construction is why it keeps flexing and holding after the glass beneath it has already failed. As an authorized dealer we install genuine 3M product, which is what keeps the manufacturer warranty and the published forced-entry data attached to your building.

3M Ultra S800

8 mil micro-layered

Best for: Interior classroom vision panels, office sidelites, door lites

  • Hundreds of tear-resistant micro-layers instead of a single thick polyester sheet
  • Stays intact and keeps flexing after the glass fractures
  • Optically clear — daylight, sightlines and classroom appearance unchanged
  • The value tier for high-count interior openings on a district budget

3M Ultra S140

14 mil micro-layered

Best for: Main entry vestibules, front office glass, ground-floor storefront

  • Our standard specification for exterior entry glazing on campuses
  • Pairs with structural wet-glaze attachment for maximum forced-entry delay
  • Holds shattered glass in the opening through repeated strikes
  • Also resists wind-borne debris during severe Texas weather

3M Ultra S240

Heaviest Ultra series laminate

Best for: High-risk entries, cash handling, government and utility glazing

  • Top of the Ultra line for the openings that must hold the longest
  • Specified where the threat profile or insurance requirement demands it
  • Combined with attachment systems for a fully engineered opening
  • Clear finish — no bars, no shutters, no change to the building's look

How we work with Texas school districts

Campus glass is the softest point on nearly every school building in the state. Unfilmed tempered glazing converts to gravel and clears the opening in one to three seconds. Filmed glazing fractures but stays in the frame, forcing an intruder into a sustained, noisy, visible effort — and those minutes are the entire premise of a lockdown protocol.

We prioritize by exposure instead of treating every pane equally: entry vestibules, front office glass, ground-floor classroom lites and portable buildings first. That is how districts get meaningful protection inside a real budget.

  • District-wide and single-campus rollouts across Texas
  • Summer, weekend and after-hours scheduling so instruction is never interrupted
  • Background-checked, badged crews and certificates of insurance on file before mobilization
  • Itemized per-opening quantities and pricing for bond, grant and allotment submissions
  • Manufacturer spec sheets and forced-entry test data supplied for district records
  • Per-campus completion documentation, photos and warranty paperwork at handoff

Security film questions we get from districts

They differ in thickness and how much abuse the laminate absorbs before it tears. S800 is an 8 mil micro-layered film we use on interior vision panels and lower-risk openings. S140 is a 14 mil laminate and our standard for exterior entry glazing. S240 is the heaviest of the Ultra series for the highest-risk openings. All three are optically clear and use 3M's tear-resistant micro-layer construction rather than a single thick polyester sheet.
