Frequently Asked Questions

Security films can withstand hurricane-force winds, accidental impact, and burglar attempts, delaying forced entry by up to 5 minutes. Advanced versions meet GSA and ASTM standards for blast mitigation.

  • Security Films: Applied externally, can be retrofitted, cost-effective.
  • Laminated Glass: Pre-installed, integrated into the glass structure, better for ballistic resistance.
    Security films are often used in combination with laminated glass for maximum protection.

Yes! Residential security films make home invasions more difficult, giving homeowners extra time to react, call 911, or trigger an alarm.

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

In ASTM F1642 & GSA testing, properly installed films reduce glass fragmentation by up to 92%, minimizing casualties in bomb explosions.

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

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

  • Single-Ply Films (4-7 mil) → Basic protection against minor impact, suitable for residential applications.
  • Multi-Ply Films (8-15 mil) → Layered construction for advanced impact absorption, ideal for high-risk zones, embassies, and storefronts.

These films use sacrificial coatings, allowing easy removal of:

  • Spray paint
  • Acid etching
  • Scratches
    They can be peeled off without affecting the original glass.

No, shutters are removable and vulnerable to forced entry, while security films remain permanently bonded to glass.

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.

Yes, incorrect film selection on insulated, Low-E, or dual-pane glass can cause thermal fractures. Professional installers check:

  • Glass type & thickness
  • Absorption rates
  • Exterior heat exposure
  • Use ammonia-free cleaners
  • Avoid sharp objects or abrasive scrubbing
  • Use microfiber cloths for best results

Yes! Security films protect storefronts, offices, and homes from looters, rocks, bats, and blunt force attacks, preventing glass shattering and property damage.

Laminated glass offers built-in protection, but security films can be retrofit onto existing glass for added reinforcement.
