Frequently Asked Questions

  • Use ammonia-free cleaners
  • Avoid sharp objects or abrasive scrubbing
  • Use microfiber cloths for best results

Yes, multi-layer security films help protect storefronts from looting, vandalism, and forced entry.

  • 8-12 mil films: Reduces injuries from flying glass fragments.
  • 15+ mil films: Used for embassies, airports, and military buildings, offering greater fragment retention.

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

Yes! Flame-retardant security films slow down flame spread and heat transfer, helping protect glass from cracking under high temperatures.

No, but they delay glass penetration when combined with:

  • Polycarbonate panels
  • Ballistic-grade laminated glass
  • Edge retention anchoring systems

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

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

Safety and security window films are multi-layered, high-tensile polyester films applied to glass surfaces to reinforce windows against breakage, forced entry, and impacts. They hold shattered glass together, reducing injury risks, property damage, and intrusion attempts.

  • 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.

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

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.

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