Frequently Asked Questions

Yes! Security films reinforce older windows, preventing breakage and shattering, but edge-retention systems may be needed for extra durability.

Yes, but performance depends on layering compatibility and proper adhesion. It’s best to apply security film first, then decorative overlays.

Films undergo testing under global security standards, including:

  • ASTM F1233 – Forced Entry Resistance (tested against blunt force attacks).
  • ASTM F1642 – Blast Resistance (measures shockwave mitigation).
  • GSA Level 1-3 Certifications – Protection levels against bomb blasts.
  • ANSI Z97.1 & EN 12600 – Impact & shatter resistance for public safety.

Yes! Security films add privacy, impact protection, and shatter resistance for glass walls in commercial spaces, schools, and conference rooms.

No, but they reduce spalling (glass fragmentation) and delay penetration, especially when combined with ballistic-rated polycarbonate glass.

Yes! Security films add shock absorption, reducing breakage risks in homes, schools, and public buildings.

  • Security Films: Transparent, impact-resistant, preserves building aesthetics.
  • Metal Bars: More secure but visually intrusive, potential fire escape hazard.

Security films are made from multi-layered polyester (PET) with proprietary coatings, including:

  • Nano-ceramic layers for heat rejection and durability.
  • UV-stabilized adhesives for long-lasting adhesion.
  • Optically clear polyurethane coatings to enhance visibility and shatter resistance.
  • Acrylic pressure-sensitive adhesives (PSA) for extreme bonding with glass surfaces.

An edge retention system (ERS) reinforces film adhesion to the frame, preventing the entire glass pane from being dislodged during:

  • Explosions
  • Forced entry attempts
  • Hurricane-force winds
  • Entry-level security films: ~25,000 psi tensile strength.
  • Blast-rated films: Up to 33,000+ psi, preventing penetration under extreme force.

Yes, some films meet UL 10B fire standards, slowing down flame spread and preventing glass from exploding under heat.

Clear security films are nearly invisible, while tinted versions add privacy and solar control.

Yes! Retail stores and commercial buildings use security films to prevent fast break-ins, making it difficult for thieves to grab merchandise and escape.

Security films disperse blast pressure across the film’s surface, reducing shockwave penetration and keeping shattered glass in place.

Yes! Films meeting ASTM F1642 or GSA TS01-2003 have been tested against blast pressures and debris impact in military, embassy, and high-risk zones.
