Frequently Asked Questions

Yes! Many security films include solar control layers, reducing heat buildup and UV exposure inside buildings.

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

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

Yes, but special retention adhesives are required for full effectiveness, ensuring the film remains bonded under impact.

  • Clear security films (90% VLT) preserve maximum visibility.
  • Tinted security films (35-50% VLT) add privacy while blocking infrared heat.

Security films can delay entry by 3-5 minutes, which can be enough time for security alerts or law enforcement response.

Yes! Security films protect large glass surfaces, including patio doors, skylights, and commercial storefronts.

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
  • Deter intruders by delaying forced entry.
  • Reduce injury risks from broken glass.
  • Improve safety in high-risk zones like front entrances & classrooms.

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 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.

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

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.

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

  • Retail & Jewelry Stores – Smash-and-grab protection.
  • Government & Military Buildings – Blast mitigation.
  • Hospitals & Laboratories – Chemical explosion prevention.
  • Schools & Universities – Active shooter and impact protection.
  • Banks & Data Centers – Theft prevention and RF shielding.
